The American Midwest is home to some of the richest, most productive farmland in the world, enabling its transformation into a vast corn- and soy-producing machine—a conversion spurred largely by decades-long policies that support the production of biofuels. But a new report takes a big swing at the ethanol orthodoxy of American agriculture, criticizing the industry for causing economic and social imbalances across rural communities and saying that the expansion of biofuels will increase greenhouse gas emissions, despite their purported climate benefits. The report, from the World Resources Institute, which has been critical of US biofuel policy in the past, draws from 100 academic studies on biofuel impacts. It concludes that ethanol policy has been largely a failure and ought to be reconsidered, especially as the world needs more land to produce food to meet growing demand. “Multiple studies show that US biofuel policies have reshaped crop production, displacing food crops and driving up emissions from land conversion, tillage, and fertilizer use,” said the report’s lead author, Haley Leslie-Bole. “Corn-based ethanol, in particular, has contributed to nutrient runoff, degraded water quality and harmed wildlife habitat. As climate pressures grow, increasing irrigation and refining for first-gen biofuels could deepen water scarcity in already drought-prone parts of the Midwest.” The conversion of Midwestern agricultural land has been sweeping. Between 2004 and 2024, ethanol production increased by nearly 500 percent. Corn and soybeans are now grown on 92 and 86 million acres of land respectively—and roughly a third of those crops go to produce ethanol. That means about 30 million acres of land that could be used to grow food crops are instead being used to produce ethanol, despite ethanol only accounting for 6 percent of the country’s transportation fuel. The biofuels industry—which includes refiners, corn and soy growers and the influential agriculture lobby writ large—has long insisted that corn- and soy-based biofuels provide an energy-efficient alternative to fossil-based fuels. Congress and the US Department of Agriculture have agreed. The country’s primary biofuels policy, the Renewable Fuel Standard, requires that biofuels provide a greenhouse gas reduction over fossil fuels: The law says that ethanol from new plants must deliver a 20 percent reduction in greenhouse gas emissions compared to gasoline. In addition to greenhouse gas reductions, the industry and its allies in Congress have also continued to say that ethanol is a primary mainstay of the rural economy, benefiting communities across the Midwest. But a growing body of research—much of which the industry has tried to debunk and deride—suggests that ethanol actually may not provide the benefits that policies require. It may, in fact, produce more greenhouse gases than the fossil fuels it was intended to replace. Recent research says that biofuel refiners also emit significant amounts of carcinogenic and dangerous substances, including hexane and formaldehyde, in greater amounts than petroleum refineries. The new report points to research saying that increased production of biofuels from corn and soy could actually raise greenhouse gas emissions, largely from carbon emissions linked to clearing land in other countries to compensate for the use of land in the Midwest. On top of that, corn is an especially fertilizer-hungry crop requiring large amounts of nitrogen-based fertilizer, which releases huge amounts of nitrous oxide when it interacts with the soil. American farming is, by far, the largest source of domestic nitrous oxide emissions already—about 50 percent. If biofuel policies lead to expanded production, emissions of this enormously powerful greenhouse gas will likely increase, too. The new report concludes that not only will the expansion of ethanol increase greenhouse gas emissions, but it has also failed to provide the social and financial benefits to Midwestern communities that lawmakers and the industry say it has. (The report defines the Midwest as Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin.) “The benefits from biofuels remain concentrated in the hands of a few,” Leslie-Bole said. “As subsidies flow, so may the trend of farmland consolidation, increasing inaccessibility of farmland in the Midwest, and locking out emerging or low-resource farmers. This means the benefits of biofuels production are flowing to fewer people, while more are left bearing the costs.” New policies being considered in state legislatures and Congress, including additional tax credits and support for biofuel-based aviation fuel, could expand production, potentially causing more land conversion and greenhouse gas emissions, widening the gap between the rural communities and rich agribusinesses at a time when food demand is climbing and, critics say, land should be used to grow food instead. President Donald Trump’s tax cut bill, passed by the House and currently being negotiated in the Senate, would not only extend tax credits for biofuels producers, it specifically excludes calculations of emissions from land conversion when determining what qualifies as a low-emission fuel. The primary biofuels industry trade groups, including Growth Energy and the Renewable Fuels Association, did not respond to Inside Climate News requests for comment or interviews. An employee with the Clean Fuels Alliance America, which represents biodiesel and sustainable aviation fuel producers, not ethanol, said the report vastly overstates the carbon emissions from crop-based fuels by comparing the farmed land to natural landscapes, which no longer exist. They also noted that the impact of soy-based fuels in 2024 was more than $42 billion, providing over 100,000 jobs. “Ten percent of the value of every bushel of soybeans is linked to biomass-based fuel,” they said.

Drones Set To Deliver Benefits for Labor-Intensive Industries: Forrester By John P. Mello Jr. June 3, 2025 5:00 AM PT ADVERTISEMENT Quality Leads That Turn Into Deals Full-service marketing programs from TechNewsWorld deliver sales-ready leads. Segment by geography, industry, company size, job title, and more. Get Started Now. Aerial drones are rapidly assuming a key role in the physical automation of business operations, according to a new report by Forrester Research. Aerial drones power airborne physical automation by addressing operational challenges in labor-intensive industries, delivering efficiency, intelligence, and experience, explained the report written by Principal Analyst Charlie Dai with Frederic Giron, Merritt Maxim, Arjun Kalra, and Bill Nagel. Some industries, like the public sector, are already reaping benefits, it continued. The report predicted that drones will deliver benefits within the next two years as technologies and regulations mature. It noted that drones can help organizations grapple with operational challenges that exacerbate risks and inefficiencies, such as overreliance on outdated, manual processes, fragmented data collection, geographic barriers, and insufficient infrastructure. Overreliance on outdated manual processes worsens inefficiencies in resource allocation and amplifies safety risks in dangerous work environments, increasing operational costs and liability, the report maintained. “Drones can do things more safely, at least from the standpoint of human risk, than humans,” said Rob Enderle, president and principal analyst at the Enderle Group, an advisory services firm, in Bend, Ore. “They can enter dangerous, exposed, very high-risk and even toxic environments without putting their operators at risk,” he told TechNewsWorld. “They can be made very small to go into areas where people can’t physically go. And a single operator can operate several AI-driven drones operating autonomously, keeping staffing levels down.” Sensor Magic “The magic of the drone is really in the sensor, while the drone itself is just the vehicle that holds the sensor wherever it needs to be,” explained DaCoda Bartels, senior vice president of operations with FlyGuys, a drone services provider, in Lafayette, La. “In doing so, it removes all human risk exposure because the pilot is somewhere safe on the ground, sending this sensor, which is, in most cases, more high-resolution than even a human eye,” he told TechNewsWorld. “In essence, it’s a better data collection tool than if you used 100 people. Instead, you deploy one drone around in all these different areas, which is safer, faster, and higher resolution.” Akash Kadam, a mechanical engineer with Caterpillar, maker of construction and mining equipment, based in Decatur, Ill., explained that drones have evolved into highly functional tools that directly respond to key inefficiencies and threats to labor-intensive industries. “Within the manufacturing and supply chains, drones are central to optimizing resource allocation and reducing the exposure of humans to high-risk duties,” he told TechNewsWorld. “Drones can be used in factory environments to automatically inspect overhead cranes, rooftops, and tight spaces — spaces previously requiring scaffolding or shutdowns, which carry both safety and cost risks,” he said. “A reduction in downtime, along with no requirement for manual intervention in hazardous areas, is provided through this aerial inspection by drones.” “In terms of resource usage, drones mounted with thermal cameras and tools for acquiring real-time data can spot bottlenecks, equipment failure, or energy leakage on the production floor,” he continued. “This can facilitate predictive maintenance processes and [optimal] usage of energy, which are an integral part of lean manufacturing principles.” Kadam added that drones provide accurate field mapping and multispectral imaging in agriculture, enabling the monitoring of crop health, soil quality, and irrigation distribution. “Besides the reduction in manual scouting, it ensures more effective input management, which leads to more yield while saving resources,” he observed. Better Data Collection The Forrester report also noted that drones can address problems with fragmented data collection and outdated monitoring systems. “Drones use cameras and sensors to get clear, up-to-date info,” said Daniel Kagan, quality manager at Rogers-O’Brien Construction, a general contractor in Dallas. “Some drones even make 3D maps or heat maps,” he told TechNewsWorld. “This helps farmers see where crops need more water, stores check roof damage after a storm, and builders track progress and find delays.” “The drone collects all this data in one flight, and it’s ready to view in minutes and not days,” he added. Dean Bezlov, global head of business development at MYX Robotics, a visualization technology company headquartered in Sofia, Bulgaria, added that drones are the most cost and time-efficient way to collect large amounts of visual data. “We are talking about two to three images per second with precision and speed unmatched by human-held cameras,” he told TechNewsWorld. “As such, drones are an excellent tool for ‘digital twins’ — timestamps of the real world with high accuracy which is useful in industries with physical assets such as roads, rail, oil and gas, telecom, renewables and agriculture, where the drone provides a far superior way of looking at the assets as a whole,” he said. Drone Adoption Faces Regulatory Hurdles While drones have great potential for many organizations, they will need to overcome some challenges and barriers. For example, Forrester pointed out that insurers deploy drones to evaluate asset risks but face evolving privacy regulations and gaps in data standardization. Media firms use drones to take cost-effective, cinematic aerial footage, but face strict regulations, it added, while in urban use cases like drone taxis and cargo transport remain experimental due to certification delays and airspace management complexities. “Regulatory frameworks, particularly in the U.S., remain complex, bureaucratic, and fragmented,” said Mark N. Vena, president and principal analyst with SmartTech Research in Las Vegas. “The FAA’s rules around drone operations — especially for flying beyond visual line of sight [BVLOS] — are evolving but still limit many high-value use cases.” “Privacy concerns also persist, especially in urban areas and sectors handling sensitive data,” he told TechNewsWorld. “For almost 20 years, we’ve been able to fly drones from a shipping container in one country, in a whole other country, halfway across the world,” said FlyGuys’ Bartels. “What’s limiting the technology from being adopted on a large scale is regulatory hurdles over everything.” Enderle added that innovation could also be a hangup for organizations. “This technology is advancing very quickly, making buying something that isn’t instantly obsolete very difficult,” he said. “In addition, there are a lot of drone choices, raising the risk you’ll pick one that isn’t ideal for your use case.” “We are still at the beginning of this trend,” he noted. “Robotic autonomous drones are starting to come to market, which will reduce dramatically the need for drone pilots. I expect that within 10 years, we’ll have drones doing many, if not most, of the dangerous jobs currently being done by humans, as robotics, in general, will displace much of the labor force.” John P.

LUBBOCK — Every winter, after the sea of cotton has been harvested in the South Plains and the ground looks barren, technicians with the High Plains Underground Water Conservation District check the water levels in nearly 75,000 wells across 16 counties. For years, their measurements have shown what farmers and water conservationists fear most—the Ogallala Aquifer, an underground water source that’s the lifeblood of the South Plains agriculture industry, is running dry. That’s because of a century-old law called the rule of capture. The rule is simple: If you own the land above an aquifer in Texas, the water underneath is yours. You can use as much as you want, as long as it’s not wasted or taken maliciously. The same applies to your neighbor. If they happen to use more water than you, then that’s just bad luck. To put it another way, landowners can mostly pump as much water as they choose without facing liability to surrounding landowners whose wells might be depleted as a result. Following the Dust Bowl—and to stave off catastrophe—state lawmakers created groundwater conservation districts in 1949 to protect what water is left. But their power to restrict landowners is limited. “The mission is to save as much water possible for as long as possible, with as little impact on private property rights as possible,” said Jason Coleman, manager for the High Plains Underground Water Conservation District. “How do you do that? It’s a difficult task.” A 1953 map of the wells in Lubbock County hangs in the office of the groundwater district. [Photo: Annie Rice for The Texas Tribune] Rapid population growth, climate change, and aging water infrastructure all threaten the state’s water supply. Texas does not have enough water to meet demand if the state is stricken with a historic drought, according to the Texas Water Development Board, the state agency that manages Texas’ water supply. Lawmakers want to invest in every corner to save the state’s water. This week, they reached a historic $20 billion deal on water projects. High Plains Underground Water District General Manager Jason Coleman stands in the district’s meeting room on May 21 in Lubbock. [Photo: Annie Rice for The Texas Tribune] But no one wants to touch the rule of capture. In a state known for rugged individualism, politically speaking, reforming the law is tantamount to stripping away freedoms. “There probably are opportunities to vest groundwater districts with additional authority,” said Amy Hardberger, director for the Texas Tech University Center for Water Law and Policy. “I don’t think the political climate is going to do that.” State Sen. Charles Perry, a Lubbock Republican, and Rep. Cody Harris, a Palestine Republican, led the effort on water in Austin this year. Neither responded to requests for comment. Carlos Rubinstein, a water expert with consulting firm RSAH2O and a former chairman of the water development board, said the rule has been relied upon so long that it would be near impossible to undo the law. “I think it’s better to spend time working within the rules,” Rubinstein said. “And respect the rule of capture, yet also recognize that, in and of itself, it causes problems.” Even though groundwater districts were created to regulate groundwater, the law effectively stops them from doing so, or they risk major lawsuits. The state water plan, which spells out how the state’s water is to be used, acknowledges the shortfall. Groundwater availability is expected to decline by 25% by 2070, mostly due to reduced supply in the Ogallala and Edwards-Trinity aquifers. Together, the aquifers stretch across West Texas and up through the Panhandle. By itself, the Ogallala has an estimated three trillion gallons of water. Though the overwhelming majority in Texas is used by farmers. It’s expected to face a 50% decline by 2070. Groundwater is 54% of the state’s total water supply and is the state’s most vulnerable natural resource. It’s created by rainfall and other precipitation, and seeps into the ground. Like surface water, groundwater is heavily affected by ongoing droughts and prolonged heat waves. However, the state has more say in regulating surface water than it does groundwater. Surface water laws have provisions that cut supply to newer users in a drought and prohibit transferring surface water outside of basins. Historically, groundwater has been used by agriculture in the High Plains. However, as surface water evaporates at a quicker clip, cities and businesses are increasingly interested in tapping the underground resource. As Texas’ population continues to grow and surface water declines, groundwater will be the prize in future fights for water. In many ways, the damage is done in the High Plains, a region that spans from the top of the Panhandle down past Lubbock. The Ogallala Aquifer runs beneath the region, and it’s faced depletion to the point of no return, according to experts. Simply put: The Ogallala is not refilling to keep up with demand. “It’s a creeping disaster,” said Robert Mace, executive director of the Meadows Center for Water and the Environment. “It isn’t like you wake up tomorrow and nobody can pump anymore. It’s just happening slowly, every year.” [Image: Yuriko Schumacher/The Texas Tribune] Groundwater districts and the law The High Plains Water District was the first groundwater district created in Texas. Over a protracted multi-year fight, the Legislature created these new local government bodies in 1949, with voter approval, enshrining the new stewards of groundwater into the state Constitution. If the lawmakers hoped to embolden local officials to manage the troves of water under the soil, they failed. There are areas with groundwater that don’t have conservation districts. Each groundwater districts has different powers. In practice, most water districts permit wells and make decisions on spacing and location to meet the needs of the property owner. The one thing all groundwater districts have in common: They stop short of telling landowners they can’t pump water. In the seven decades since groundwater districts were created, a series of lawsuits have effectively strangled groundwater districts. Even as water levels decline from use and drought, districts still get regular requests for new wells. They won’t say no out of fear of litigation. The field technician coverage area is seen in Nathaniel Bibbs’ office at the High Plains Underground Water District. Bibbs is a permit assistant for the district. [Photo: Annie Rice for The Texas Tribune] “You have a host of different decisions to make as it pertains to management of groundwater,” Coleman said. “That list has grown over the years.” The possibility of lawsuits makes groundwater districts hesitant to regulate usage or put limitations on new well permits. Groundwater districts have to defend themselves in lawsuits, and most lack the resources to do so. A well spacing guide is seen in Nathaniel Bibbs’ office. [Photo: Annie Rice for The Texas Tribune] “The law works against us in that way,” Hardberger, with Texas Tech University, said. “It means one large tool in our toolbox, regulation, is limited.” The most recent example is a lawsuit between the Braggs Farm and the Edwards Aquifer Authority. The farm requested permits for two pecan orchards in Medina County, outside San Antonio. The authority granted only one and limited how much water could be used based on state law. It wasn’t an arbitrary decision. The authority said it followed the statute set by the Legislature to determine the permit. “That’s all they were guaranteed,” said Gregory Ellis, the first general manager of the authority, referring to the water available to the farm. The Braggs family filed a takings lawsuit against the authority. This kind of claim can be filed when any level of government—including groundwater districts—takes private property for public use without paying for the owner’s losses. Braggs won. It is the only successful water-related takings claim in Texas, and it made groundwater laws murkier. It cost the authority $4.5 million. “I think it should have been paid by the state Legislature,” Ellis said. “They’re the ones who designed that permitting system. But that didn’t happen.” An appeals court upheld the ruling in 2013, and the Texas Supreme Court denied petitions to consider appeals. However, the state’s supreme court has previously suggested the Legislature could enhance the powers of the groundwater districts and regulate groundwater like surface water, just as many other states have done. While the laws are complicated, Ellis said the fundamental rule of capture has benefits. It has saved Texas’ legal system from a flurry of lawsuits between well owners. “If they had said ‘Yes, you can sue your neighbor for damaging your well,’ where does it stop?” Ellis asked. “Everybody sues everybody.” Coleman, the High Plains district’s manager, said some people want groundwater districts to have more power, while others think they have too much. Well owners want restrictions for others, but not on them, he said. “You’re charged as a district with trying to apply things uniformly and fairly,” Coleman said. Can’t reverse the past Two tractors were dropping seeds around Walt Hagood’s farm as he turned on his irrigation system for the first time this year. He didn’t plan on using much water. It’s too precious. The cotton farm stretches across 2,350 acres on the outskirts of Wolfforth, a town 12 miles southwest of Lubbock. Hagood irrigates about 80 acres of land, and prays that rain takes care of the rest. Walt Hagood drives across his farm on May 12, in Wolfforth. Hagood utilizes “dry farming,” a technique that relies on natural rainfall. [Photo: Annie Rice for The Texas Tribune] “We used to have a lot of irrigated land with adequate water to make a crop,” Hagood said. “We don’t have that anymore.” The High Plains is home to cotton and cattle, multi-billion-dollar agricultural industries. The success is in large part due to the Ogallala. Since its discovery, the aquifer has helped farms around the region spring up through irrigation, a way for farmers to water their crops instead of waiting for rain that may not come. But as water in the aquifer declines, there are growing concerns that there won’t be enough water to support agriculture in the future. At the peak of irrigation development, more than 8.5 million acres were irrigated in Texas. About 65% of that was in the High Plains. In the decades since the irrigation boom, High Plains farmers have resorted to methods that might save water and keep their livelihoods afloat. They’ve changed their irrigation systems so water is used more efficiently. They grow cover crops so their soil is more likely to soak up rainwater. Some use apps to see where water is needed so it’s not wasted. A furrow irrigation is seen at Walt Hagood’s cotton farm. [Photo: Annie Rice for The Texas Tribune] Farmers who have not changed their irrigation systems might not have a choice in the near future. It can take a week to pump an inch of water in some areas from the aquifer because of how little water is left. As conditions change underground, they are forced to drill deeper for water. That causes additional problems. Calcium can build up, and the water is of poorer quality. And when the water is used to spray crops through a pivot irrigation system, it’s more of a humidifier as water quickly evaporates in the heat. According to the groundwater district’s most recent management plan, 2 million acres in the district use groundwater for irrigation. About 95% of water from the Ogallala is used for irrigated agriculture. The plan states that the irrigated farms “afford economic stability to the area and support a number of other industries.” The state water plan shows groundwater supply is expected to decline, and drought won’t be the only factor causing a shortage. Demand for municipal use outweighs irrigation use, reflecting the state’s future growth. In Region O, which is the South Plains, water for irrigation declines by 2070 while demand for municipal use rises because of population growth in the region. Coleman, with the High Plains groundwater district, often thinks about how the aquifer will hold up with future growth. There are some factors at play with water planning that are nearly impossible to predict and account for, Coleman said. Declining surface water could make groundwater a source for municipalities that didn’t depend on it before. Regions known for having big, open patches of land, like the High Plains, could be attractive to incoming businesses. People could move to the country and want to drill a well, with no understanding of water availability. The state will continue to grow, Coleman said, and all the incoming businesses and industries will undoubtedly need water. “We could say ‘Well, it’s no one’s fault. We didn’t know that factory would need 20,000 acre-feet of water a year,” Coleman said. “It’s not happening right now, but what’s around the corner?” Coleman said this puts agriculture in a tenuous position. The region is full of small towns that depend on agriculture and have supporting businesses, like cotton gins, equipment and feed stores, and pesticide and fertilizer sprayers. This puts pressure on the High Plains water district, along with the two regional water planning groups in the region, to keep agriculture alive. “Districts are not trying to reduce pumping down to a sustainable level,” said Mace with the Meadows Foundation. “And I don’t fault them for that, because doing that is economic devastation in a region with farmers.” Hagood, the cotton farmer, doesn’t think reforming groundwater rights is the way to solve it. What’s done is done, he said. “Our U.S. Constitution protects our private property rights, and that’s what this is all about,” Hagood said. “Any time we have a regulation and people are given more authority, it doesn’t work out right for everybody.” Rapid population growth, climate change, and aging water infrastructure all threaten the state’s water supply. [Photo: Annie Rice for The Texas Tribune] What can be done The state water plan recommends irrigation conservation as a strategy. It’s also the least costly water management method. But that strategy is fraught. Farmers need to irrigate in times of drought, and telling them to stop can draw criticism. In Eastern New Mexico, the Ogallala Land and Water Conservancy, a nonprofit organization, has been retiring irrigation wells. Landowners keep their water rights, and the organization pays them to stop irrigating their farms. Landowners get paid every year as part of the voluntary agreement, and they can end it at any point. Ladona Clayton, executive director of the organization, said they have been criticized, with their efforts being called a “war” and “land grab.” They also get pushback on why the responsibility falls on farmers. She said it’s because of how much water is used for irrigation. They have to be aggressive in their approach, she said. The aquifer supplies water to the Cannon Air Force Base. “We don’t want them to stop agricultural production,” Clayton said. “But for me to say it will be the same level that irrigation can support would be untrue.” There is another possible lifeline that people in the High Plains are eyeing as a solution: the Dockum Aquifer. It’s a minor aquifer that underlies part of the Ogallala, so it would be accessible to farmers and ranchers in the region. The High Plains Water District also oversees this aquifer. If it seems too good to be true—that the most irrigated part of Texas would just so happen to have another abundant supply of water flowing underneath—it’s because there’s a catch. The Dockum is full of extremely salty brackish water. Some counties can use the water for irrigation and drinking water without treatment, but it’s unusable in others. According to the groundwater district, a test well in Lubbock County pulled up water that was as salty as seawater. Rubinstein, the former water development board chairman, said there are pockets of brackish groundwater in Texas that haven’t been tapped yet. It would be enough to meet the needs on the horizon, but it would also be very expensive to obtain and use. A landowner would have to go deeper to get it, then pump the water over a longer distance. “That costs money, and then you have to treat it on top of that,” Rubinstein said. “But, it is water.” Landowners have expressed interest in using desalination, a treatment method to lower dissolved salt levels. Desalination of produced and brackish water is one of the ideas that was being floated around at the Legislature this year, along with building a pipeline to move water across the state. Hagood, the farmer, is skeptical. He thinks whatever water they move could get used up before it makes it all the way to West Texas. There is always brackish groundwater. Another aquifer brings the chance of history repeating—if the Dockum aquifer is treated so its water is usable, will people drain it, too? Hagood said there would have to be limits.

Submitted by WA Contents Three circular volumes create Villa Noon in Sotogrande designed by Fran Silvestre Arquitectos Spain Architecture News - May 30, 2025 - 12:29   html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd" Valencia-based architecture practice Fran Silvestre Arquitectos has revealed design for a house composed of three circular volumes in Sotogrande, Spain.Named Villa Noon, the house is thoughtfully incorporated into a topographically defined setting, utilizing the slope of the ground to open each volume onto a distinct horizon. In order to achieve visual harmony with the natural environment without leaving an unwelcome footprint on the landscape, the house's layout, which is divided into five circular sections, was designed to seamlessly blend with the surroundings.Every one of these pieces has a rear patio that offers protection from the strongest winds and a front terrace that shields from the sun. In addition to optimizing orientation, this circular geometry reduces the volumetric impact, enabling the building to interact with the landscape in a controlled and deliberate manner. The outside materiality gradually integrates into its surroundings because it was constructed from indigenous Sierra Elvira stone, which has white veins and grey tones. This organic texture will eventually blend in as though it were a natural feature of the relief of the ground.A spacious, open vestibule that serves as a threshold between the outside and the inside of the villa is the entryway. It is surrounded by a curved wall. Visitors are introduced to a series of chambers that adjust to the various terrain levels in this transitional area. While the day area unfolds on a lower platform, open to the landscape and directly connected to the outdoors, the night area is located on a higher level, apart from the other functions.The well-being areas, like the gym, are located on the same floor and provide both practical and visual connections to the separate visitor area. Each zone's privacy is protected by this tiered arrangement, which also keeps the composition's overall spatial continuity flexible. By combining geothermal and aerothermal technologies, the house produces an excess of electricity and becomes energy self-sufficient. A mechanism for atmospheric water condensation is also included, which draws moisture from the air for household usage.Techniques including choosing native plant species based on their water requirements, utilizing natural mulch to prevent evaporation, and installing a drip irrigation system that only turns on when required are used to cut down on water usage in the garden. While infiltration trenches, also known as swales, filter and direct rainfall, green roofs enhance insulation and collect rainfall. This system is completed by permeable surfaces and cisterns, which enable the collected water to be stored and used again.By taking these steps, the house also becomes self-sufficient in water, which is a very reasonable objective in this region of Spain, which is the wettest in the nation due to the Sierra de Grazalema."We have always been fascinated by how the Namib Desert beetle collects water: in an extremely arid environment, this insect tilts its body into the wind to condense fog on its shell, whose surface combines areas that attract water and others that repel it, allowing the droplets to slide directly into its mouth," said Fran Silvestre Arquitectos."A natural lesson in efficiency that inspires and reinforces the logic of this system," the firm added.The idea is reminiscent of architectural works like Kazuyo Sejima's Villa in the Forest and Arne Jacobsen's Leo Henriksen House, whose circular shapes and attention to the environment served as inspiration. In contrast to radiocentric solutions, this proposal chooses what we refer to as "the squaring of the circle": service areas are included into irregularly shaped zones, while residential spaces are resolved through an orthogonal floor plan. In the end, we anticipate that this architecture will blend in with its surroundings over time, appearing to be a component of a karstic relief.SketchRoof level planFirst floor planGround floor planBasement floor planSectionRecently, Fran Silvestre Arquitectos unveiled design for a winery with curvacious form adressing winemaking process in Zayas de Báscones, Soria, Spain. In addition, the firm completed a house featuring irregularly shifted volumes on an irregularly shaped plot within Altos de Valderrama, in Sotogrande, Spain.Project factsProject name: Villa NoonArchitects: Fran Silvestre ArquitectosLocation: Sotogrande, Spain.Developer: Cork Oak MansionAll renderings & drawings courtesy of Fran Silvestre Arquitectos.> via Fran Silvestre Arquitectos

Got a project that’s too wild for this world? Submit your conceptual works, images and ideas for global recognition and print publication in the 2025 Vision Awards, June 6th marks the end of the Main Entry period — click here to submit your work. What does the future of architecture hold? How will tomorrow’s buildings look, feel, and interact with the existing human-made environment? Which innovations are primed to help us reduce the footprint of construction, improve liveability, and redefine our idea of and relationship to space? These are the questions Architizer’s Vision Awards look to answer (or, at least offer some suggestions in lieu of concrete answers). Dedicated to the planned and unbuilt, which may or may not ever be, nominations represent one of our most unique human traits — the ability to imagine possibilities and impossibilities, to dream big and think well into unchartered territory. Unbuilt architecture, whether it is planned for construction or destined to remain on “paper,” should be more present in a newscycle of press releases for recently constructed or newly opened buildings. Indeed, many of the ideas presented in such projects directly respond to emerging crises exacerbated by our continued reliance on 20th-century practice’s approaches and materiality. Meanwhile, the evolution of architectural visualization allows architects to develop their wildest ideas and to communicate their boldest visions with more clarity and urgency than ever before. Kyathos I Mass Timber Arena by KAAF I Kitriniaris Associates Architecture Firm, Βεΐκου, Galatsi, Greece Many studios are looking to re-write the script with high tech innovations that simply would not have been possible in the recent past, or emphasize the urgent need to get back to traditional building styles that utilize natural resources and passive principles in a bid to bring down carbon emissions and other outputs with negative environmental impact. The Kyathos Mass Timber Basketball Arena proposal does both. It’s fitting that we should look at this concept in spring 2025. The Osaka Expo recently opened in Japan and features the largest free-standing wooden structure ever built. The Grand Ring encases the event site and a section of its coastal waters with a circumference of 61,035 square meters (656,975 square feet). To us, it reflects what is possible when modern engineering meets one of the world’s most sustainable materials. Likewise, realizing a size previously unthinkable with wood, Alexander Kitriniaris’ KAAF I Kitriniaris Associates Architecture Firm‘s plans for this Greek sports stadium offer a new vision for the athletic facility typology.  Kyathos I Mass Timber Arena by KAAF I Kitriniaris Associates Architecture Firm, Βεΐκου, Galatsi, Greece Employing a composite timber load bearing system, the project — commissioned by Galatsi Municipality — comprises a main court, spectator stands, internal mezzanine and gallery running the perimeter, changing rooms for athletes and referees, toilets, offices, and auxiliary spaces. Its total surface area is 4,000 square meters (43, 055 square feet), all of which complement the location. Designed for the site of an older, smaller wooden gymnasium, which fails to meet modern standards and is scheduled for demolition, the aesthetics reflect the surrounding Mediterranean flora grove. The name Kyathos refers to a type of painted pottery cup popularized in ancient Greece. The design of this was based on the petals of a milkweed belonging to the Euphorbia genus of plants. The countryside in this region is home to around forty such species, making the entire building an ode to indigenous nature and culture that has been here for millennia. When realized, it will stand in sharp contrast to the stereotype of arenas and stadiums most fans across the world have grown accustomed to, which often seem to have landed in situ, from another district if not planet. Kyathos I Mass Timber Arena by KAAF I Kitriniaris Associates Architecture Firm, Βεΐκου, Galatsi, Greece Above the main court level, the building’s structure is composed entirely of engineered wood, including glue-laminated timber, cross-laminated timber, and plywood. A timber support frame wraps the indoor gymnasium in a precise 45-by-30-meter (148-by-98 foot) rectangular grid. The roof is formed by ten identical isostatic frames. Symmetrical in design, these triple-arched assemblies combine beams and posts, reinforced where necessary by discreet metal connectors and stiffeners. Overhead, a lightweight polymer roof — waterproof, UV-resistant, recyclable, and printable — ensures durable protection while minimizing weight. In the renderings, an elegant lattice-like pattern, calls attention to these delicate considerations. At the heart of the design, the firm’s plans and visualizations emphasize, lies a bioclimatic structural shell (pictured below), conceived to provide constant shade while optimizing natural ventilation, daylighting, and passive cooling. Meanwhile, rainwater collected from the roof and shaped surfaces is reused for on-site irrigation, supporting the lush Mediterranean flora of the existing grove. Kyathos I Mass Timber Arena by KAAF I Kitriniaris Associates Architecture Firm, Βεΐκου, Galatsi, Greece This year, Saudi Arabia has begun working towards the World Cup 2034. Set to be held in November that year due to the incompatibility of regional climate and international football — or football at any level — the environmental price tag for this edition of the planet’s biggest soccer tournament is likely to be huge. While recent years have seen major strides taken to improve the impact of competitive sports, with last year’s Paris Olympics achieving more than 50% carbon reduction compared with the previous two Games, there are clear differences in what’s needed to host matches in cities like Jeddah and Riyadh. Not to mention the ultra-futurist urban experiment, NEOM — a metropolis that doesn’t exist yet.   Even during winter months, average temperatures across the desert state sit at a very hot 29°C. Humidity is high in coastal areas, while frost and snow are not uncommon overnight on higher ground. While it’s too early to tell the footprint of the vast mega-stadiums we’ve been promised for the competition, heating and cooling requirements are almost certainly going to be immense. We are, after all, experiencing a surge in global temperatures year-on-year and an increase in weather extremes of all kinds, and this will have significantly worsened in another ten years. More so, whether we’re powered with renewables or dinosaur fossils, high energy consumption of all types is not sustainable in the real sense.  Kyathos I Mass Timber Arena by KAAF I Kitriniaris Associates Architecture Firm, Βεΐκου, Galatsi, Greece Analyzing the legitimacy, authenticity and suitability of Saudi Arabia as a World Cup host nation is a conversation for another time. Perhaps another publication. But the fundamental point is we urgently need to rethink and reprioritize non-essential undertakings for the sake of the climate and our planet. When seen through this lens, the plans for Kyathos in Greece act as a symbol of progress and sets benchmarks for a future in which we acknowledge the need for our passions to be in balance with the Earth, rather imposing upon it. The fact this is achieved through an homage to a history in which we were more aligned to nature, and associated materials, but also utilizes modern engineering techniques and manufacturing methods of those materials, only accentuates the masterful vision behind this design.  Given the number of projects that will be designed between now and the stadium’s project 2028 construction date, and the ever-increasing concentration of carbon in our atmosphere, its urgent that we begin celebrating such plans now — while they’re still plans — rather than waiting for the design to become a physical building. After all, architecture starts before you put two bricks together (or, in this case, two pieces of timber). Learn More About Vision Awards Got a project that’s too wild for this world?

No Mow May encourages homeowners to stash the lawn mower each spring and let flowers and grass grow for pollinators and water retention. And if your neighbor’s lawn already looks like a wildflower field most of the time, it could be more intentional than passersby might assume.The movement has expanded to “Let It Bloom June” and the fall version: “Leave the leaves.” Conservation and horticulture groups say year-round low-mowing while selectively leaving native plants to grow can save huge amounts of drinking water and lead to lasting and impactful ecological changes.When Amanda Beltramini Healan moved into her Nashville ranch house in 2016, the yard had been manicured for sale: a walnut tree, roses from a home improvement store and short grass. So she experimented, first with a 10-by-10-foot patch where she dug up the grass and sowed native seeds. Then she planted goldenrods in the culvert near the street, and let more of her yard grow tall without mowing.Local authorities apparently didn’t appreciate her natural look: “I got a letter from the city saying that I had to mow it,” she said.But then, a friend told her about No Mow Month signs, provided by the Cumberland River Compact, a local water conservation nonprofit. Soon she was signaling to the city that she’s no derelict, but a participant in an international movement.These days, every month is No Mow May in parts of her property. While she keeps the growth shorter near the culvert and street, her backyard is filled with native grasses and plants up to her knees or waist. There’s a decomposing tree trunk where scores of skinks and bugs live, birds nest under her carport and she regularly finds fawns sleeping in the safety of the high grasses.“I have a lot of insects and bugs and that’s protein, so the birds and the bird’s nests are everywhere. Cardinals and wrens and cowbirds and robins,” she said. “I wake up to them, especially during spring migration right now. It’s just a cacophony in the morning and in the evening, especially when the mulberries come in.”The movement is popularized by groups such as Plantlife, a conservation organization based in England.American lawns, based on English and French traditions, are increasingly seen as a wasteful monoculture that encourages an overuse of pesticides, fertilizer and water. Outdoor spraying and irrigation account for over 30% of a U.S. household’s total water consumption, and can be twice that in drier climates, according to the EPA.Some criticize No Mow campaigns as a fad that could invite invasive plants to spread unchecked without helping pollinators much, if only done for a month.A guide outlining No Mow pros, cons and limitations, written by consumer horticulture extension specialist Aaron Steil at Iowa State University, says reducing mowing to every two weeks and replacing turf with plants that pollinate all year long can offer more benefits without risking a citation or complaints.The No Mow effort does encourage people to think more about biodiversity in their yards, and many local nature organizations advise provide guidance on picking noninvasive plants that fit each region’s climate and precipitation levels.Reducing mowing encourages longer-rooted native grasses and flowers to grow, which breaks up compacted soil and improves drainage, “meaning that when it rains, more water is going to be captured and stored in lawns versus being generated as a runoff and entering into our stormwater system,” said Jason Sprouls, urban waters program manager for the Cumberland River Compact.Beltramini Healan isn’t just letting just anything grow — she learned which plants are invasive, non-native or not beneficial to the ecosystem and carefully prunes and weeds so the keepers have room to thrive.Nashville homeowner Brandon Griffith said he was just tired of mowing when he decided years ago wait and see what comes up. Then he consciously added flowering plants to attract bees and bugs. Now he sees so many insects and pollinators all over his garden that the neighbors’ kids come over to look for butterflies.It’s about giving them the time “to come out of their larva or their egg stage and be able to grow,” said Griffith. He said he’s never heard a complaint — in fact, some of his neighbors also stopped mowing for a month each spring. His four-year-old son catches lizards, digs for worms and hunts for bugs in the yard.“I just enjoy coming out and walking around,” said Griffith. “And looking at it, it’s kind of peaceful. It’s kinda relaxing.”__This story has been updated to correct the spelling of Amanda Beltramini Healan’s name and to correct that Aaron Steil works at Iowa State University, not the University of Iowa. —Kristin M.

The US is less than 250 years old, but some of its most important archaeological sites are older than the Viking seafarers, the Roman Empire, and the pyramids.Many help tell the story of how the first humans came to North America. It's still a mystery exactly how and when people arrived, though it's widely believed they crossed the Bering Strait at least 15,000 years ago."As we get further back in time, as we get populations that are smaller and smaller, finding these places and interpreting them becomes increasingly difficult," archaeologist Kenneth Feder told Business Insider. He's the author of "Ancient America: Fifty Archaeological Sites to See for Yourself."Some sites, like White Sands and Cooper's Ferry, have skeptics about the accuracy of their age. Still, they contribute to our understanding of some of the earliest Americans.Others are more recent and highlight the different cultures that were spreading around the country, with complex buildings and illuminating pictographs.Many of these places are open to the public, so you can see the US' ancient history for yourself. White Sands National Park, New Mexico Footprints at White Sands. National Park Service Prehistoric camels, mammoths, and giant sloths once roamed what's now New Mexico, when it was greener and damper.As the climate warmed around 11,000 years ago, the water of Lake Otero receded, revealing footprints of humans who lived among these extinct animals. Some even seemed to be following a sloth, offering a rare glimpse into ancient hunters' behavior.Recent research puts some of these fossilized footprints at between 21,000 and 23,000 years old. If the dates are accurate, the prints would predate other archaeological sites in the US, raising intriguing questions about who these people were and how they arrived in the Southwestern state."Where are they coming from?" Feder said. "They're not parachute dropping in New Mexico. They must have come from somewhere else, which means there are even older sites." Archaeologists simply haven't found them yet.While visitors can soak in the sight of the eponymous white sands, the footprints are currently off-limits. Meadowcroft Rockshelter, Pennsylvania The archeological dig at the Meadowcroft National Historic Site in 2013. AP Photo/Keith Srakocic In the 1970s, archaeologist James M. Adovasio sparked a controversy when he and his colleagues suggested stone tools and other artifacts found in southwestern Pennsylvania belonged to humans who had lived in the area 16,000 years ago.For decades, scientists had been finding evidence of human habitation that all seemed to be around 12,000 to 13,000 years old, belonging to the Clovis culture. They were long believed to have been the first to cross the Bering land bridge. Humans who arrived in North America before this group are often referred to as pre-Clovis.At the time, skeptics said that the radiocarbon dating evidence was flawed, AP News reported in 2016. In the years since, more sites that appear older than 13,000 years have been found across the US.Feder said Adovasio meticulously excavated the site, but there's still no clear consensus about the age of the oldest artifacts. Still, he said, "that site is absolutely a major, important, significant site." It helped archaeologists realize humans started arriving on the continent before the Clovis people.The dig itself is on display at the Heinz History Center, allowing visitors to see an excavation in person. Cooper's Ferry, Idaho Excavators at Cooper's Ferry in 2013. Loren Davis/Oregon State University One site that's added intriguing evidence to the pre-Clovis theory is located in western Idaho. Humans living there left stone tools and charred bones in a hearth between 14,000 and 16,000 years ago, according to radiocarbon dating. Other researchers put the dates closer to 11,500 years ago.These stemmed tools are different from the Clovis fluted projectiles, researchers wrote in a 2019 Science Advances paper.Some scientists think humans may have been traveling along the West Coast at this time, when huge ice sheets covered Alaska and Canada. "People using boats, using canoes could hop along that coast and end up in North America long before those glacial ice bodies decoupled," Feder said.Cooper's Ferry is located on traditional Nez Perce land, which the Bureau of Land Management holds in public ownership. Page-Ladson, Florida Divers search in the sediment at the Page-Ladson site. Texas A&M University via Getty Images In the early 1980s, former Navy SEAL Buddy Page alerted paleontologists and archaeologists to a sinkhole nicknamed "Booger Hole" in the Aucilla River. There, the researchers found mammoth and mastodon bones and stone tools.They also discovered a mastodon tusk with what appeared to be cut marks believed to be made by a tool. Other scientists have returned to the site more recently, bringing up more bones and tools. They used radiocarbon dating, which established the site as pre-Clovis."The stone tools and faunal remains at the site show that at 14,550 years ago, people knew how to find game, fresh water and material for making tools," Michael Waters, one of the researchers, said in a statement in 2016. "These people were well-adapted to this environment."Since the site is both underwater and on private property, it's not open to visitors. Paisley Caves, Oregon One of the Paisley Caves near Paisley, Oregon. AP Photo/Jeff Barnard Scientists study coprolites, or fossilized poop, to learn about the diets of long-dead animals. Mineralized waste can also reveal much more. In 2020, archaeologist Dennis Jenkins published a paper on coprolites from an Oregon cave that were over 14,000 years old.Radiocarbon dating gave the trace fossils' age, and genetic tests suggested they belonged to humans. Further analysis of coprolites added additional evidence that a group had been on the West Coast 1,000 years before the Clovis people arrived.Located in southcentral Oregon, the caves appear to be a piece of the puzzle indicating how humans spread throughout the continent thousands of years ago.The federal Bureau of Land Management owns the land where the caves are found, and they are listed on the National Register of Historic Places. Swan Point, Alaska Excavators working at the Swan Point site in June 2016. Charles Holmes/University of Alaska, Fairbanks Whenever people arrived in the Americas, they crossed from Siberia into Beringia, an area of land and sea between Russia and Canada and Alaska. Now it's covered in water, but there was once a land bridge connecting them.The site in Alaska with the oldest evidence of human habitation is Swan Point, in the state's eastern-central region. In addition to tools and hearths dating back 14,000 years, mammoth bones have been found there.Researchers think this area was a kind of seasonal hunting camp. As mammoths returned during certain times of the years, humans would track them and kill them, providing plentiful food for the hunter-gatherers.While Alaska may have a wealth of archaeological evidence of early Americans, it's also a difficult place to excavate. "Your digging season is very narrow, and it's expensive," Feder said. Some require a helicopter to reach, for example. Blackwater Draw, New Mexico A palaeontologist excavating a mammoth in Portales, New Mexico, circa 1960. Dick Kent/FPG/Archive Photos/Getty Images In 1929, 19-year-old James Ridgley Whiteman found mammoth bones along with fluted projectile points near Clovis, New Mexico. The Clovis people who made these tools were named for this site.Researchers studying the site began to realize the artifacts found at the site belonged to different cultures. Clovis points are typically larger than Folsom flutes, which were first found at another archaeological site in New Mexico.For decades after Whiteman's discovery, experts thought the Clovis people were the first to cross the Bering land bridge from Asia around 13,000 years ago. Estimates for humans' arrival is now thought to be at least 15,000 years ago.Eastern New Mexico University's Blackwater Draw Museum grants access to the archaeological site between April and October. Upper Sun River, Alaska Excavations at the Upward Sun River, Alaska. Ben Potter/University of Alaska, Fairbanks One reason the dates of human occupation in North America is so contentious is that very few ancient remains have been found. Among the oldest is a child from Upward Sun River, or Xaasaa Na', in Central Alaska.Archaeologists found the bones of the child in 2013. Local indigenous groups refer to her as Xach'itee'aanenh t'eede gay, or Sunrise Girl-Child. Genetic testing revealed the 11,300-year-old infant belonged to a previously unknown Native American population, the Ancient Beringians.Based on the child's genetic information, researchers learned that she was related to modern Native Americans but not directly. Their common ancestors started becoming genetically isolated 25,000 years ago before dividing into two groups after a few thousand years: the Ancient Berignians and the ancestors of modern Native Americans.According to this research, it's possible humans reached Alaska roughly 20,000 years ago. Poverty Point National Monument, Louisiana Poverty Point in Louisiana. National Park Service Stretching over 80 feet long and 5 feet tall, the rows of curved mounds of Poverty Point are a marvel when viewed from above. Over 3,000 years ago, hunter-gatherers constructed them out of tons of soil. Scientists aren't sure exactly why people built them, whether they were ceremonial or a display of status.The artifacts various groups left behind indicate the site was used off and on for hundreds of years and was a meeting point for trading. People brought tools and rocks from as far as 800 miles away. Remains of deer, fish, frogs, alligators, nuts, grapes, and other food have given archaeologists insights into their diets and daily lives.You can see the World Heritage Site for yourself year-round. Horseshoe Canyon, Utah The Great Gallery in Horseshoe Canyon. Neal Herbert/National Park Service Though remote, the multicolored walls of Horseshoe Canyon have long attracted visitors. Some of its artifacts date back to between 9,000 and 7,000 BCE, but its pictographs are more recent. Some tests date certain sections to around 2,000 to 900 years ago.The four galleries contain life-sized images of anthropomorphic figures and animals in what's known as the Barrier Canyon style. Much of this art is found in Utah, produced by the Desert Archaic culture.The pictographs may have spiritual and practical significance but also help capture a time when groups were meeting and mixing, according to the Natural History Museum of Utah.It's a difficult trek to get to the pictographs (and the NPS warns it can be dangerously hot in summer) but are amazing to view in person, Feder said. "These are creative geniuses," he said of the artists. Canyon de Chelly, Arizona The Antelope House at Canyon de Chelly National Monument. Michael Denson/National Park Service Situated in the Navajo Nation, Canyon de Chelly has gorgeous desert views and thousands of years of human history. Centuries ago, Ancestral Pueblo and Hopi groups planted crops, created pictographs, and built cliff dwellings.Over 900 years ago, Puebloan people constructed the White House, named for the hue of its clay. Its upper floors sit on a sandstone cliff, with a sheer drop outside the windows.Navajo people, also known as Diné, still live in Canyon de Chelly. Diné journalist Alastair Lee Bitsóí recently wrote about visiting some of the sacred and taboo areas. They include Tsé Yaa Kin, where archaeologists found human remains.In the 1860s, the US government forced 8,000 Navajo to relocate to Fort Sumner in New Mexico. The deadly journey is known as the "Long Walk." Eventually, they were able to return, though their homes and crops were destroyed.A hike to the White House is the only one open to the public without a Navajo guide or NPS ranger. Mesa Verde National Park, Colorado Visitors line up at Mesa Verde National Park. Shutterstock/Don Mammoser In the early 1900s, two women formed the Colorado Cliff Dwelling Association, hoping to preserve the ruins in the state's southwestern region. A few years later, President Theodore Roosevelt signed a bill designating Mesa Verde as the first national park meant to "preserve the works of man."Mesa Verde National Park holds hundreds of dwellings, including the sprawling Cliff Palace. It has over 100 rooms and nearly two dozen kivas, or ceremonial spaces.Using dendrochronology, or tree-ring dating, archaeologists learned when Ancestral Pueblo people built some of these structures and that they migrated out of the area by the 1300s.Feder said it's his favorite archaeological site he's visited. "You don't want to leave because you can't believe it's real," he said.Tourists can view many of these dwellings from the road, but some are also accessible after a bit of a hike. Some require extra tickets and can get crowded, Feder said. Cahokia, Illinois A mound at Cahokia in Illinois. Matt Gush/Shutterstock Cahokia has been called one of North America's first cities. Not far from present-day St. Louis, an estimated 10,000 to 20,000 people lived in dense settlements roughly 1,000 years ago. Important buildings sat atop large mounds, which the Mississippians built by hand, The Guardian reported.At the time, it was thriving with hunters, farmers, and artisans. "It's an agricultural civilization," Feder said. "It's a place where raw materials from a thousand miles away are coming in." Researchers have also found mass graves, potentially from human sacrifices.The inhabitants built circles of posts, which one archaeologist later referred to as "woodhenges," as a kind of calendar. At the solstices, the sun would rise or set aligned with different mounds.After a few hundred years, Cahokia's population declined and disappeared by 1350. Its largest mound remains, and some aspects have been reconstructed.While Cahokia is typically open to the public, parts are currently closed for renovations. Montezuma Castle, Arizona Montezuma Castle, a cliff dwelling, in Arizona. MyLoupe/Universal Images Group via Getty Images Perched on a limestone cliff in Camp Verde, Arizona, this site is an apartment, not a castle, and is unrelated to the Aztec ruler Montezuma.The Sinagua people engineered the five-story, 20-room building around 1100. It curves to follow the natural line of the cliff, which would have been more difficult than simply making a straight building, Feder said."These people were architects," he said. "They had a sense of beauty."The inhabitants were also practical, figuring out irrigation systems and construction techniques, like thick walls and shady spots, to help them survive the hot, dry climate.Feder said the dwelling is fairly accessible, with a short walk along a trail to view it, though visitors can't go inside the building itself.

The Missing Room / Carroccera CollectiveSave this picture!•Italy Architects: Carroccera Collective Year Completion year of this architecture project Year:  2025 Photographs Photographs: Lead Architects: Gianfrancesco Brivio Sforza, Dariia Nepop, Nacha Palomeque Coll, Caspar Schols, Angelica Rimoldi More SpecsLess Specs Save this picture! Text description provided by the architects. The Missing Room is a living space designed to encourage new rituals and patterns of use, offering an opportunity to enter an alternative time zone and experience a passage between a human-controlled environment and an untamed natural one. It is a room that has escaped the rigid confines of a defined house, choosing to exist without walls or a ceiling – a place where nature becomes the main inhabitant and visitors are invited to act as respectful guests. As one enters the Carroccera landscape, the search begins. Meandering through the land, the Missing Room gradually reveals itself, with the wanderer catching shimmering glimpses of smaller secondary structures shining through the forest greenery. This collection of visual fragments prepares the visitor for the main encounter, enriching the landscape with its enigmatic shapes and forms.Save this picture!Save this picture!Save this picture!The Missing Room is not simply a shelter but a space that invites discovery. A collection of abstract forms with a core activated by water and fire, it reimagines the most primal human rituals: resting, eating, cleansing, and conversing. These activities mix in unexpected yet harmonious ways. While guests cook over a crackling open fire, another inhabitant bathes in a heated bath, and a cow drinks from an integrated trough—all beneath a ceiling of tree canopies and the open sky. This space encourages visitors to set their own pace and redefine their pre-existing notions of domesticity. At the core of the Missing Room stands a seven-meter-tall monolith: a multifunctional chimney. On one side, the fire powers the ovens, while on the other, it heats water for bathing and warms the area at the front of the space. This towering form responds to the scale of the surrounding trees, rising like a beacon above the canopies, marking its presence in the landscape and guiding visitors with its smoke signals.Save this picture!Save this picture!Water, like fire, plays a central role in activating the hidden features of the structure. The water flow is released at the entrance of the structure, filling the main collection channel that distributes the flow into various basins throughout the structure. Users are encouraged to interact with the water systems by adding or removing plugs as needed to direct the flow; to fill the bath, use the sink or supply water to the cattle trough. The bath next to the water channel has a built-in natural convection system and comfortably accommodates three to four people. For solo use, the bath's size can be reduced with a partitioning panel and a removable lock to conserve water. Once closed, the bath can be transformed into a heated surface and used as a resting place to sleep at night under the stars.Save this picture!Save this picture!Save this picture!A bespoke sail canopy can be set up to offer shade or protection from rain. Using the chimney as a mast, the fabric is raised with a series of ropes and tensioned at the corners with ground pegs. By day, the canopy catches dappled shadows cast by the surrounding foliage; by night, it reflects light from built-in recessed lighting, transforming the structure into a glowing lantern. The Missing Room reconnects us with the rhythms of nature that have been lost in the contemporary world by reducing the act of dwelling to its very essence. Forest debris is gathered and converted into heat while the wastewater from bathing and cooking is filtered and safely dispersed into the field, providing irrigation and wet areas that contribute to the overall biodiversity of the forest.Save this picture!© Alessandro NanniConstructed with a focus on material and structural sustainability, the stainless steel refuge is durable, recyclable, and resistant to weathering. To protect the land, the modular structure and use of a non-invasive screw-pile foundation ensures that no traces are left behind if the house is required to be removed from the site. The Missing Room is a space for all – humans and non-humans – to share. Above all, the Carroccera Collective conceived of the room as a place to enjoy the very act of being. To invite our guests to slow down, reorient the senses, and rediscover the sensory richness and simplicity of the natural environment. As nature has vanished from our daily rituals and gone missing from our human lives, the room is a space to reveal the forgotten.Save this picture!

Latin America at the 2025 Venice Biennale: Exploring Territory, Memory, and Ancestral Knowledge to Build the PresentSave this picture!Andamio Vivo - Perú. Image © Gonzalo Vera Tudela De MontreuilThe 19th edition of the Venice Architecture Biennale officially opened to the public on May 10, becoming a significant international platform for exploring the current state of global architecture and sparking conversations about the challenges the discipline faces today—both shared and specific to each territory. This year’s theme, "Intelligens. Natural. Artificial. Collective," proposed by general curator and Italian architect Carlo Ratti, invites reflection on architecture’s interconnection with other fields—such as art, artificial intelligence, and technology—while also emphasizing the importance of territories, landscapes, and, above all, the people who collectively shape our built environment.In this context, the national participations of Latin American countries have enriched the international exhibition with contributions deeply rooted in their local cultures and identities. Argentina, Brazil, Chile, Mexico, Peru, and Uruguay represented Central and South America in Venice. Across their proposals, several shared themes emerged—most notably, the idea that contemporary architecture must consciously reconnect with its territory and draw from its history in order to build more thoughtfully today. Along these lines, the installations explored the re-signification of local elements and ancestral knowledge, adapting them to contemporary challenges and contexts.Brazil and Mexico centered their exhibitions on an in-depth investigation of land recording and mapping, addressing the use of ancestral construction technologies in relation to agriculture and the natural landscape. Both explored how these traditional techniques can be adapted to contemporary contexts. Uruguay, recognizing that over half of its territory is composed of water, emphasized the importance of considering this resource as an integral part of the country’s history, culture, and development. Peru and Argentina, meanwhile, focused on the re-signification of unique local elements—the silobag, emblematic of the Argentine countryside, and totora, a plant traditionally used in various forms of construction in Peru. In both pavilions, these materials were prominently featured, evoking the cultural and symbolic significance they carry. Finally, Chile’s participation presented a reflective and thought-provoking working table that examined recent debates around artificial intelligence policies established in the country. Related Article Between Algorithms and Ancestral Knowledge: Expanding the Concept of Architectural Intelligence Siestario - Argentina Save this picture!Save this picture!Upon entering Siestario, the Argentine Pavilion located in the Arsenale of Venice, visitors are immersed in a space of soft light and evocative soundscapes. At the center, serving as the undisputed focal point, is a large pink inflatable bag that instinctively invites repose. This is a silobag—a storage element commonly used in the Argentine countryside for preserving grain, especially soy, and emblematic of the country’s export-driven economy. In this context, the silobag functions not only as a spatial gesture but also as a temporal one: an invitation to pause and reflect amid the pace of the Biennale.In this way, architects Marco Zampieron and Juan Manuel Pachué succeed in decontextualizing this characteristic element—deeply rooted in national identity—by re-signifying its function and placing it within a space of critique and questioning. The result is effective: visitors are drawn to the installation, climb onto it, rest, and surrender to the experience, surrounded by images and sounds that induce a dreamlike drowsiness.(re) invenção - BrazilSave this picture!Save this picture!Brazil’s exhibition, curated by Luciana Saboia, Eder Alencar, and Matheus Seco—members of Plano Coletivo—is divided into two rooms, presenting research on the knowledge drawn from the lands of the Amazon. The installation establishes a dialogue between ancestral wisdom and contemporary urban infrastructure through exhibition elements that also serve as the structural system of the display.In the first room, lined with biodegradable wooden panels, maps and documents are spread across the floor, evoking the direct relationship that Indigenous peoples of the Amazon have with their land. In the second, a curated selection of architectural and urban infrastructure projects illustrates how these traditional forms of knowledge—deeply connected to Brazilian territory—are transformed into collective knowledge, capable of adapting to contemporary projects while preserving this cultural heritage.This balance between local culture, territory, and contemporary challenges is expressed almost literally through a minimalist and precise installation, composed of vertical panels and a suspended table made of reforested wood, both connected by tensioned steel cables. The balance is achieved through stone counterweights and a central metal tube that distributes the forces, turning the table into a structural element that redefines the spatial experience of the room.Reflective Intelligences - ChileSave this picture!Save this picture!The Chilean Pavilion presents a powerful proposal: upon entering the room, a central table—the main exhibition element—reflects a series of videos, essays, and images on its water surface. These works focus on archival research exploring the country’s growing role in the development of artificial intelligence, data center buildings, and the impact this has on the territory and, above all, its inhabitants.Serena Dambrosio, Nicolás Díaz Bejarano, and Linda Schilling Cuellar, the architects behind the pavilion, conceive the table not only as a physical support but also as a reference to the political tool of the "roundtable" used by the Chilean government to introduce policies and regulations around AI. In this case, the use of the water’s reflection invites visitors to reflect on what this technological development truly entails, questioning the exclusion of communities and environmental factors in these decision-making spaces. In this way, the table within the pavilion becomes a fertile ground for fostering collective dialogue among all key stakeholders: architects, researchers, communities, and policymakers.Chinampa Veneta - MéxicoSave this picture!Save this picture!The experience of entering the Mexican Pavilion, located in the Arsenale at the Biennale, is completely immersive. Visitors are welcomed by a recreation of a chinampa—an ancient cultivation system that involves creating platforms of earth over water to form small agricultural islands—which immediately captures attention through its lush vegetation, the scent of damp soil, and the sounds of water. The rest of the room, where vegetables, flowers, and medicinal herbs planted in the central chinampa are also expected to grow, is arranged to mimic the canals of Xochimilco, drawing a parallel with Venice itself, famously built over water.With this installation, the curatorial team—comprising Estudio Ignacio Urquiza and Ana Paula de Alba, Estudio María Marín de Buen, ILWT, Locus, Lucio Usobiaga Hegewisch & Nathalia Muguet, and Pedro&Juana—proposes revisiting these traditional chinampa agricultural systems to reflect on their adaptation in the present as a sustainable response, thanks to their self-irrigation system, within the context of droughts and global climate crisis. It also stands as evidence of a collective system bridging the natural and the built environment, as well as sustained care over time.Living Scaffolding - PerúSave this picture!Save this picture!The Peruvian Pavilion, with Alex Hudtwalcker as chief curator and Sebastián Cillóniz, José Ignacio Beteta, and Gianfranco Morales as associate curators, is presented at the Biennale’s Arsenale with Living Scaffolding, a proposal centered around a monumental structure built from totora reed wood. This installation brings to Venice the ancestral knowledge of the Uros and Aymara peoples of Lake Titicaca, who for centuries have used totora to construct floating habitable islands, homes, boats, and other essential elements for life on the lake.Over time, the refinement of this ancient technique incorporated other essential components—such as ropes and logs—that contribute to the stability and buoyancy of the structures. All this knowledge is materialized in an installation that can be fully experienced: visitors enter and walk through the scaffolding, exploring its construction system from within.Living Scaffolding highlights the technical precision and enduring relevance of this tradition, which in the contemporary context takes on a new meaning connected to collectivity, material memory, and the possibility of reactivating ancestral techniques as a response to today’s challenges. 53,86% Uruguay Land of Water - Uruguay Save this picture!Save this picture!Curated by architects Ken Sei Fong and Katia Sei Fong, alongside visual artist Luis Sei Fong, the Uruguayan Pavilion explores the country’s relationship with its maritime territory, which accounts for just over half of its total surface area. Located in its own building within the Biennale’s Giardini, the pavilion features a poetic and musical installation: a wavy ceiling from which amethyst stones hang, dripping water that strikes metal containers on the floor. This sensory and sonic experience invites visitors to contemplate water as a thread that weaves together the country’s memory, identity, and development.The installation presents a critique of the global water management model, emphasizing that, as a finite and increasingly scarce resource, it is essential to establish policies and regulations for its preservation. In this context, architecture plays a key role: it can not only offer innovative solutions but also promote conscious planning around water in cities and territories, acting as a bridge between the way we inhabit and the way we collectively manage this vital resource.Save this picture!Latin America’s participation in the 2025 Venice Biennale reveals that architecture is not only a design discipline but also a powerful critical and cultural tool. Each pavilion, rooted in its specific territorial context and local cultural identity, enacts a form of resistance by exploring ancestral knowledge, natural resources, and contemporary technologies as collective ways of knowing—learning from the past to build better today. In a global context marked by environmental crises, inequalities, and technological transformations, these architectural and deeply reflective endeavors construct new and reimagined narratives, where the local is no longer intrinsic to a fixed context but rather knowledge that expands, connects, and adapts to shared new realities.Save this picture!
