(Should we coin the term “auto-architecture?”) Perhaps this isn’t a perfect analogy, but it certainly contains parallels that are productive to parse… Studio spaces are distinct from offices in that they not only shape daily rituals and structure relationships between colleagues but also act as an expression of the values at the core of the firm’s design philosophies. Freed from the usual constraints of client briefs, for many firms, designing their own workspace offers a unique opportunity for experimentation and self-expression. The studios featured in this collection span diverse geographies and contexts — from a vaulted school library repurposed as an “anti-office,” to a carbon-neutral warehouse conversion in Sydney, to a minimalist tiled atelier in Casablanca. Despite their differences, each workspace shares a commitment to thoughtful design that blurs the line between functions and offers a vision for cultivating creativity. More than places of production, these studios are active expressions of architectural identity; spaces that support not only what architects make, but how they make it. They also challenge outdated typologies and embrace the hybrid realities of contemporary practice. Skylab HQ By Skylab, Portland, Oregon After spending years in a historic structure in downtown Portland, the Skylab team decided the time had come to create a space that reflected the dynamic nature of their practice. They asked themselves: “How can our studio evolve from a dedicated workspace to a playground for the art and design community? Where can we find a space to integrate gardens, an event venue, and a fabrication shop, as well as our studio?” Leaving the downtown core, they opted to transform a pair of WWII-era prefabricated steel warehouses into a hybrid studio, fabrication lab and cultural venue supporting both architectural production and artistic exchange. Strategic insertions — like a 60-foot-long (18-meter) ridge skylight, 10-foot (3-meter) operable window walls and CLT-framed meeting rooms — maximize daylight and material contrast, balancing industrial grit with biophilic warmth. The adaptive reuse reflects the firm’s ethos of experimentation, extending their design process into the very architecture that houses it. Alexander House By Alexander &CO., Sydney, Australia Jury Winner, Architecture +Workspace, 10th Annual A+Awards Alexander House functions as both studio and experimental prototype, integrating low-carbon construction with hybrid live/work spatial typologies tailored to an evolving architectural practice. While functioning as an architectural residential showcase, the team also works from this home, and their clients meet with them there; the project challenges preconceptions of home, land, family and work. From a voluminous material library in the basement to a concrete mezzanine bench designed for quiet focus, the layout supports varied modes of design work while challenging conventional boundaries between domestic and professional space. Crafted in collaboration with local makers, the building also pioneers sustainability through reclaimed timber linings, carbon-neutral bricks, and a solar system supplying up to 80% of daily energy demand. say architects Community Office By say architects, Hangzhou, China Say Architects’ office reimagines workplace architecture as a life-oriented, materially expressive environment, where exposed I-beams structure both the building and the studio’s daily rhythms. Cantilevered volumes, rope-grown greenery, and integrated misting systems animate the exterior, while steel-framed shelving and model rooms of rich timber textures create a tactile, inspiration-driven interior. Prioritizing adaptability and sensory comfort, the space dissolves traditional partitions in favor of spatial arrangements that align with design habits, offering a studio that is both tool and manifesto. Bohlin Cywinski Jackson, Philadelphia Studio By Bohlin Cywinski Jackson, Philadelphia, Pennsylvania Bohlin Cywinski Jackson’s Philadelphia studio transforms a historic social club (founded in 1923) into a contemporary workspace through adaptive reuse, prioritizing flexibility, daylight and material economy. The goal was to create a highly flexible work environment that would allow designers to move quickly between individual work, impromptu discussions and group meetings throughout the day. Restored terrazzo floors and ornamental detailing anchor a modern layout featuring hoteling desks, collaborative mezzanine zones and panoramic views of the city center.  The design supports agile workflows and hybrid collaboration while integrating repurposed custom furnishings to extend the life cycle of past projects. ADND OFFICE By Atelier Design N Domain, Mumbai, India ADND’s new Bombay headquarters is a richly layered adaptive reuse of a century-old industrial warehouse, reimagined as an expressive design laboratory charged with material experimentation and symbolic nuance. The studio’s soaring central bay reaches 26 feet (8 meters) in height, punctuated by 7-foot (2-meter) pivoting porthole windows that flood the workspace with southern light, evoking a cathedral-like ambiance. Throughout, bespoke interventions — from terrazzo-cast floors and mirrored reception desks to hand-sketched upholstery and looped oak chairs — translate the founders’ personal design dialects into architectural form, creating a space where industrial memory and contemporary authorship converge. Studio Cays X Studio BO By Studio CAYS, Casablanca, Morocco In this Casablanca-based studio, minimalist rigor meets material clarity through tiled walls and seamless epoxy flooring, crafting a luminous, low-maintenance workspace. At its core, a central bench anchors the open-plan layout, fostering daily collaboration and reinforcing the studio’s emphasis on shared ideation within a purified architectural envelope. Smart Design Studio By smart design studio, Alexandria, Australia Jury Winner, Office Interiors (<25,000 sq ft); Jury Winner, Office Building Low Rise, 10th Annual A+Awards Smart Design Studio’s headquarters fuses industrial heritage with cutting-edge sustainability, transforming a conserved warehouse into a carbon-neutral workspace powered by on-site energy and water collection systems. The studio’s open-plan interior is crowned by a mezzanine framed by original steel trusses, while a striking vaulted residence above features self-supporting brick catenary arches — an elegant synthesis of structural economy and sculptural ambition. Designed to reflect the material restraint and innovation of early industrial architecture, the building is a working manifesto for the studio’s interdisciplinary ethos. Architect’s Office at Kim Yam Road By Park + Associates, Singapore Popular Choice Winner, Office Interiors, 10th Annual A+Awards Photos by Edward Hendricks Occupying a former library hall atop a repurposed 1960s school, this studio embraces the latent grandeur of its barrel-vaulted, column-free volume to craft a boundary-less, anti-office environment. Full-height louvered windows invite daylight and breeze through the arching space, while the design resists conventional programming in favor of layered, informal settings that foster creativity and fluid collaboration. Rather than overwrite its past, the intervention amplifies the building’s inherent spatial expression; through adaptive reuse, the architects position atmosphere as architecture.

Heydar Aliyev Center | © Olivier Blanchette via Unsplash In contemporary architectural discourse, the building envelope is no longer a passive partition but a dynamic interface capable of interaction, regulation, and adaptation. Amid rising environmental complexity and performance demands, composite materials are emerging as enablers of this transformation. Their potential goes far beyond lightweight strength; composites are redefining what intelligence means in architectural materiality. As the industry pivots toward energy-conscious design, real-time responsiveness, and multi-functional skins, composites provide structural solutions and performative systems. In this context, the envelope becomes a site of intelligence. From Passive Shells to Active Systems For centuries, architectural skins served primarily as barriers, blocking weather, enclosing space, and symbolizing permanence. But the 21st century demands more. We require façades that filter air and light, mediate thermal flux, integrate sensors, and generate power. Traditional materials, limited by monolithic performance and weight, have struggled to adapt. Composites, by contrast, are inherently systemic. They are engineered layers rather than singular substances. Through the integration of fibers and matrices, composites enable architectural envelopes that perform structurally while accommodating embedded systems such as thermal insulation, acoustic control, impact resistance, and photoreactivity. These characteristics make them prime candidates for high-performance envelopes in buildings and infrastructure alike. In the Qatar Integrated Railway Project, composite roofing and FRP façade panels were employed to meet the demands of the harsh desert environment. This solution reduced structural loads and improved thermal performance while ensuring long-term durability in a climate defined by extremes. Performance Layering and Embedded Intelligence What distinguishes composites from conventional materials is their capacity to combine multiple performance layers in one unified system. Instead of applying insulation, waterproofing, and cladding in sequence, a composite panel can consolidate these into a single prefabricated, high-performance element. A compelling example is the Eco Casa in Australia, designed by Ian Wright, which used frameless DuFLEX composite panels. The result was an environmentally conscious home with significantly reduced material waste, enhanced thermal performance, and minimized emissions. These outcomes demonstrate how composites offer design efficiency and ecological responsibility. The capacity for prefabrication and integration is particularly valuable in settings where labor conditions, transportation logistics, or weather exposure make traditional multi-layered construction inefficient or impractical. Composites with a Nervous System: Sensing the Built Environment Recent innovations in smart composites extend these capabilities further. By embedding fiber-optic or piezoresistive sensors into composite assemblies, architects and engineers can develop building skins that sense stress, temperature changes, humidity, or vibration in real-time. These responsive façades can feed data into building management systems, enabling performance optimization or alerting maintenance teams to signs of wear or structural fatigue. This functionality has been successfully explored in transport infrastructure. The King Abdullah High-Speed Rail Station in Saudi Arabia used 27-meter composite sandwich panels to span vast distances with minimal support. The lightweight system reduced the need for extensive reinforcement while enabling thermal and mechanical performance in a climate that demands resilience. Such examples are foundational to a future in which architecture does not merely resist the environment but interprets it. Formal Freedom Meets Functional Responsiveness Guangzhou Opera House | © Scarbor Siu via Unsplash Beyond embedded intelligence, composites also expand formal expression. Their moldability, especially with parametric design and digital fabrication, allows for envelopes that curve, fold, and morph in unattainable ways with conventional rigid materials. The Guangzhou Opera House, designed by Zaha Hadid Architects, is a defining example. Advanced composite assemblies that merged structural demands with formal ambition enabled its seamless curvatures and sharp transitions. These systems supported high-precision details and complex geometries while reducing material weight and installation complexity. This freedom extends to smaller-scale yet equally ambitious projects. At the Tilburg School for VAVO, translucent composite panels embedded with knitted textiles reference local craft while offering thermal performance and design cohesion. Such examples show that intelligence in architecture includes cultural sensitivity as well as technical adaptability. Toward Circular and Regenerative Envelopes The sustainability potential of composites is often overlooked. While early generations relied heavily on fossil-derived materials, newer systems use bio-based resins, natural fibers like flax and basalt, and recyclable matrices that fit into circular design models. Composite panels can now be designed for disassembly, repurposing, or reintegration into new construction, minimizing waste and conserving embodied energy. The Pasarela de Almuñécar in Spain exemplifies this ethos. As the world’s longest carbon-fiber walkway, it replaced heavier materials and extended structural lifespan while reducing maintenance. The project signals how composites can fulfill both technical and ecological ambitions. Efforts to embed digital tracking into panels, such as RFID tags, also support long-term monitoring and facilitate reuse planning. This vision aligns with emerging concepts like material passports, which will play a critical role in lifecycle accountability. Pasarela de Almuñécar in Spain | © Luis Garcia, CC by 3.0 Overcoming Barriers to Adoption Despite the clear advantages, composite adoption in architecture still faces notable hurdles. First is the challenge of integration with legacy materials such as concrete, stone, or steel. Connection detailing requires careful coordination to ensure structural continuity and thermal performance. Second is the perception of cost. While composites may require a higher upfront investment, their lower maintenance demands, improved energy performance, and reduced structural requirements often result in favorable long-term economics. Finally, regulatory frameworks continue to evolve. Building codes have been slow to reflect the unique properties of composites, although this is changing as standardization increases and successful pilot projects proliferate. A Vision for the Future: Architecture as Adaptive Intelligence Composites are not merely substitutes for traditional materials. They represent a paradigm shift in how we understand performance, integration, and the role of material in space-making. As architecture becomes increasingly data-driven, climate-responsive, and energy-conscious, the intelligent envelope will become the norm rather than the exception. Composites make this future feasible by offering structural capability, aesthetic freedom, environmental stewardship, and embedded intelligence within a single engineered solution. From high-speed rail terminals to cultural landmarks, these materials are shaping a new kind of architecture that listens, learns, and evolves. It is no longer sufficient for architecture to stand still. The next generation of buildings must adapt, interact, and perform. Composites make that future tangible.

Version 1.0.0 By Robert Jan van Pelt (Park Books, 2025) The largest artifact in the touring exhibition Auschwitz. Not Long Ago. Not Far Away., currently on display at the ROM in Toronto, is a wooden barracks building. It’s from the Auschwitz-Monowitz camp, a satellite to Auschwitz created to provide slave labour to the IG Farben corporation for the construction of a synthetic rubber factory.  The discovery of a sister building, back in 2012, led exhibition chief curator and architectural historian Robert Jan van Pelt, University Professor at the Waterloo School of Architecture, on a research journey to write a comprehensive history of the barracks—temporary buildings that have not only housed prisoners, but also provided shelter for military servicemen and women, refugees, and natural disaster survivors. “Many people have experienced, for shorter or longer time periods, life in a barrack, and for all of them it represented life on the edge, for better or worse,” writes Van Pelt. Worm’s eye axonometric of Renkioi Hospital Barrack, a prefabricated hospital designed by Ismabard Kingdom Brunel for a site in Turkey, 1857. Van Pelt’s book criss-crosses with ease through architectural history, military history, and the history of medicine—all of which played crucial roles in the evolving development of this seemingly simple building type. The book is arranged in a dozen episodes, with the barrack at the centre of each, serving as an anchor point for unfolding the rich intellectual and historical context shaping the way these structures were developed and deployed. The book is richly illustrated with archival materials—a feat in itself, given that the documentation for temporary buildings, particularly before 1900, is scarce. These drawings, photos, and paintings are supplemented with 20 worm’s eye views of key buildings, carefully composed by a team of Waterloo architecture school students and alumni.  Thomas Thomaszoon, View of the headquarters of the Spanish in the Huis tea Kleef during the siege of Haarlem, 1572-73. Collection of Noord-Hollands Archief, Haarlem; courtesy Robert Jan van Pelt Like many vernacular buildings, temporary structures larger than a tent, designed to house soldiers in the field, have existed at least since Ancient Rome. One of the first visual accounts of barracks came centuries later, in the winter of 1572, when the Spanish laid siege to the Dutch city of Haarlem, and cartographer Thomas Thomaszoon sketched the position of dozens of Spain’s wood-and-straw structures outside the city. The siege was successful, but only a few years later, the Dutch Republic gained the upper hand. As part of the creation of a standing army, they began to develop more precise instructions for the layout of camps, including the construction of temporary barracks.

Collection of Bilbliothèque Nationale de France, Paris. Courtesy Robert Jan van Pelt The Napoleonic army made use of barracks in both military camps and training camps; by the mid-1800s, the construction of various barrack types was detailed in field construction manuals issued to officers in many European armies. During the Crimean War (1853-56), over 3,500 prefabricated barracks were manufactured in a Gloucester factory, as a solution to the appalling conditions at the front. But when the structures arrived at port, British forces were not able to unload and erect them—the materials for a single building weighed more than two tons, and each would require 60 horses (or 150 men) to transport to camp on the muddy roads.  The US (Union) Army’s Lincoln Hospital, Washington, DC, 1865. Collection of Library of Congress, Washington, DC. Courtesy Robert Jan van Pelt Prefabrication was also used, with somewhat more success, towards the end of the conflict to erect field hospitals designed by British engineer Isambard Kingdom Brunel with a priority on cross-ventilation to limit the spread of disease. Low mortality rates from similar structures led to a continued preference for “barrack hospitals” based on groupings of low-slung, well-ventilated pavilions, rather than conceived as single grand structures. The model was further refined with the addition of primitive underfloor heating and ridge ventilation by former surgeon William A. Hammond for the Union Army during the American Civil War (1861-65).  Barrack hospitals were constructed for civilian use, as well. Following the conclusion of the Franco-Prussian war (1870-71), such designs were built to house patients with infectious diseases in Berlin and proposed as a means to bring professional medical care to Germany’s rural areas. A barracks-inspired hospital was built in Saint Petersburg, Russia, in 1889, and continues to be operational.  If the barrack as an accommodation for the sick is a progressive tale, the 19th-century history of the barrack is equally checkered by the building type’s use for prisoner accommodation, including in the penal colonies of Australia and French Guiana. In North America, barracks were used in an internment camp for Native American Dakotas, and Civil War-era Union barracks at Camp Douglas were used to house Confederate prisoners. The oldest preserved barrack in the world may be in Canada, at Grosse Isle national park. Here, barrack-style quarantine sheds were used to detain thousands of Irish immigrant families during the typhoid fever epidemic of 1846-47, and their damp, fetid conditions contributed to many deaths—an episode Van Pelt describes as a “blot on the national consciousness of Canada.” A single Doecker Hut contains an operation room, pharmacy and hospital management office. The prefabricated, portable hospitals were developed in 1885, and used around the world, including in the First World War. In America, they were marketed for managing epidemics in the wake of the 1892 typhus fever outbreak in New York. Courtesy Berlin State Library and Robert Jan van Pelt   At the turn of the 19th century, the prefabricated portable barrack came to the fore with the manufacturing of the Doecker barracks, by Christoph & Unmack, a firm based in Copenhagen and Germany. Developed by a former military officer-turned-tentmaker, the technically sophisticated model used large rectangular frames that could be clipped together, and covered with “felt-cardboard”—dense felt pressed onto canvas and impregnated with linseed oil. The self-supporting structures proved easy to set up, dismount, and transport, making them suitable for both military applications—and, with little modification, for humanitarian aid. The Red Cross deployed Doecker barracks for use as field hospitals in Manchuria and Yokohama during the Russo-Japanese War (1904-05).  The Barrack, 1572-1914 wraps up in in the early 20th century, but with the note that in the ensuing decades until 1945, millions of barracks were produced by many of the world’s major nations—and that most of these were erected in barbed-wire-ringed compounds. “This is the period in which tens if not hundreds of millions of people, many of whom were civilians, were forced to live in barracks, as refugees, as expellees, as civilian internees, as forced laborers, as prisoners or war, as concentration camp prisoners, and as people made homeless by the destruction wrought by war,” writes Van Pelt. Up until 1914, he notes, this building type largely carried a sense of achievement—an image that would change sharply with the Age of the Camps. But although a WWII barrack was responsible for instigating Van Pelt’s initial investigation, that time period will need to await a second volume on this simple building type with a rich, complex, and complicated history.   As appeared in the June 2025 issue of Canadian Architect magazine  The post Book Review: The Barrack, 1572-1914—Chapters in the History of Emergency Architecture appeared first on Canadian Architect.

The housing catalogue includes 50 low-rise home designs, including for garden suites, duplexes, four-plexes and six-plexes. Each design was developed by local architecture and engineering teams with the intent of aligning with regional building codes, planning rules, climate zones, construction methods and materials. TEXT John Lorinc RENDERINGS Office In Search Of During the spring election, the Liberals leaned into messaging that evoked a historic moment from the late 1940s, when Ottawa succeeded in confronting a severe housing crisis.  “We used to build things in this country,” begins Prime Minister Mark Carney in a nostalgic ad filled with archival images of streets lined with brand new post-World War II “strawberry box” bungalows, built for returning Canadian soldiers and their young families.  The video also includes montages from the now-iconic design “catalogues,” published by Canada Mortgage and Housing Corporation (CMHC). These supplied floor plans and unlocked cheap mortgages for tens of thousands of simple suburban houses found in communities across the country. “The government built prefabricated homes that were easy to assemble and inexpensive,” Carney said in the voice-over. “And those homes are still here.”  Over the past year, CMHC has initiated a 21st century re-do of that design catalogue, and the first tranche of 50 plans—for garden suites, duplexes, four-plexes and six-plexes—went live in early March. A second tranche, with plans for small apartments, is under development.  Unlike the postwar versions, these focus on infill sites, not green fields. One of CMHC’s goals is to promote so-called gentle density to residential properties with easily constructed plans that reflect regional variations, local zoning and building-code regulations, accessibility features and low-carbon design. As with those postwar catalogues, CMHC’s other goal was to tamp down on soft costs for homeowners or small builders looking to develop these kinds of housing by providing no-cost designs that were effectively permit sets. The early reviews are generally positive. “I find the design really very compelling in a kind of understated way,” says SvN principal Sam Dufaux. By making available vetted plans that can be either pre-approved or approved as of right, CMHC will remove some of the friction that impedes this scale of housing. “One of the elements of the housing crisis has to do with how do we approve these kinds of projects,” Dufaux adds. “I’m hoping it is a bit of a new beginning.” Yet other observers offer cautions about the extent to which the CMHC program can blunt the housing crisis. “It’s a small piece and a positive one,” says missing middle advocate and economist Mike Moffatt, who is executive in residence at the Smart Prosperity Institute and an assistant professor at Western’s Ivey Business School. “But [it’s] one that probably captures a disproportionate amount of attention because it’s something people can visualize in a way that they can’t with an apartment tax credit.” This kind of new-build infill is unlikely to provide much in the way of affordable or deeply affordable housing, adds Carolyn Whitzman, housing and social policy researcher, and author of Home Truths: Fixing Canada’s Housing Crisis (UBC Press, 2024). She estimates Canada needs about three million new dwellings that can be rented for $1,000 per month or less. The policies that will enable new housing at that scale, she says, involve financing subsidies, publicly owned land, and construction innovation, e.g., prefabricated or factory-built components, as well as “consistent and permissive zoning and consistent and permissive building codes.”  Indeed, the make-or-break question hovering over CMHC’s design catalogue is whether municipalities will green-light these plans or simply find new ways to hold up approvals.   An axonometric of a rowhouse development from the Housing Catalogue, designed for Alberta. A team effort Janna Levitt, partner at LGA Architectural Partners, says that when CMHC issued an RFP for the design catalogue, her firm decided to pitch a team of architects and peer reviewers from across Canada, with LGA serving as project manager. After they were selected, Levitt says they had to quickly clarify a key detail, which was the assumption that the program could deliver pre-approved, permit-ready plans absent a piece of property to build on. “Even in 1947,” she says, “it wasn’t a permit set until you had a site.” LGA’s team and CMHC agreed to expand the scope of the assignment so that the finished product wasn’t just a catalogue of plans but also included details about local regulations and typical lot sizes. Re-Housing co-founder Michael Piper, an associate professor at U of T’s John H. Daniels Faculty of Architecture, Landscape, and Design, came on board to carry out research on similar programs, and found initiatives in places like Georgia, Indiana and Texas. “I have not found any that moved forward,” he says. “Canada’s national design catalogue is pretty novel in that regard, which is exciting.” The noteworthy exceptions are California, which has made significant advances in recent years in pre-approving ADUs across the state, and British Columbia, which last fall released its own standardized design catalogue.  He also carried out a scan of land use and zoning rules in Ontario for 15 to 20 municipalities. “We looked to see [what] their zoning permitted and what the rules were, and as you might expect, they’re all over the place,” he says. “Hence the challenge with the standardized design.” At present, high-level overviews for the 50 designs are available, including basic floor plans, 3D axonometrics, and building dimensions. Full architectural design packages are expected to be released later this year. Levitt says the architects on the team set out to come up with designs that used wood frame construction, had no basements (to save on cost and reduce embodied carbon), and drew on vernacular architectural styles. They researched representative lot sizes in the various regions, and configured designs to suit small, medium and large properties. Some versions have accessibility features—CMHC’s remit included both accessible units and aging-in-place as objectives—or can be adapted later on.  As for climate and energy efficiency considerations, the recommended materials include low-carbon components and cladding. The designs do reflect geographical variations, but Levitt says there’s only so much her team could do in terms of energy modelling. “How do you do heat energy calculations when you don’t have a site? You don’t have north, south, east, west [orientations] and you don’t have what zone are you in. In B.C. and Ontario, there are seven climatic regions. There was a lot of working through those kinds of very practical requirements, which were very complicated and actually fed into the design work quite significantly.” As Levitt adds, “in 1947, there were no heat loss models because the world wasn’t like that.” LGA provided the architects on the team with templates for interior elements, such as bathrooms, as well as standards for features such as bedroom sizes, dining areas, storage sufficient to hold strollers, and access to outdoor space, either at grade or via a balcony. “We gathered together these ideas about the quality of life that we wanted baked into each of the designs, so that [they] expressed a really good quality of life—modest but good quality,” she says. “It’s not about the finishes. People had to be able to live there and live there well.” “This isn’t a boutique home solution,” Whitzman says. “This is a cheap and mass-produced solution. And compared to other cheap and mass-produced solutions, whether they be condos or suburban subdivisions, [the catalogue designs] look fine to my untrained eye.” A selection of Housing Catalogue designs for the Atlantic region. Will it succeed?  With the plans now public, the other important variables, besides their conformity with local bylaws, have to do with cost and visibility to potential users, including homeowners, contractors and developers specializing in smaller-scale projects.  On the costing side, N. Barry Lyons Consultants (NBLC) has been retained by CMHC to develop models to accompany the design catalogue, but those figures have yet to be released. While pricing is inevitably dynamic, the calculus behind the entire exercise turns on whether the savings on design outlays and the use of prefabricated components will make such small-scale projects pencil, particularly at a time when there are live concerns about tariffs, skilled labour shortages, and supply chain interruptions on building materials.  Finally, there’s the horse-to-water problem. While the design catalogue has received a reasonable amount of media attention since it launched, does CMHC need to find ways to market it more aggressively? “From my experience,” says Levitt, “they are extremely proactive, and have assembled a kind of dream team with a huge range of experience and expertise. They are doing very concerted and deep work with municipalities across the country.” Proper promotion, observes Moffatt, “is going to be important in particular, just for political reasons. The prime minister has made a lot of bold promises about [adding] 500,000 homes.” Carney’s pledge to get Canada back into building will take time to ramp up, he adds. “I do think the federal government needs to visibly show progress, and if they can’t point to a [new] building across the road, they could at least [say], `We’ve got this design catalogue. Here’s how it works. We’ve already got so many builders and developers looking at this.’”  While it’s far too soon to draw conclusions about the success of this ambitious program, Levitt is well aware of the long and rich legacy of the predecessor CMHC catalogues from the late 40s and the 1950s, all of which gave many young Canadian architects their earliest commissions and then left an enduring aesthetic on countless communities across Canada.   She hopes the updated 21st-century catalogue—fitted out as it is for 21st-century concerns about carbon, resilience and urban density—will acquire a similar cachet.  “These are architecturally designed houses for a group of people across the country who will have never lived in an architecturally designed house,” she muses. “I would love it if, 80 years from now, the consistent feedback [from occupants] was that they were able to live generously and well in those houses, and that everything was where it should be.” ARCHITECTURE FIRM COLLABORATORS Michael Green Architecture, Dub Architects, 5468796 Architecture Inc, Oxbow Architecture, LGA Architectural Partners, KANVA Architecture, Abbott Brown Architects, Taylor Architecture Group  As appeared in the June 2025 issue of Canadian Architect magazine  The post A housing design catalogue for the 21st century appeared first on Canadian Architect.

First conducted in the spring of 2018, this survey showed that 3,149 people were in a vulnerable situation at the time. Four years later, a similar effort revealed that Montreal’s homeless population had risen to 4,690 people—and that there were some 10,000 people experiencing homelessness in the whole of the province. The 2025 numbers are expected to be significantly higher. For the organizers, this one-night snapshot of the situation is “neither perfect nor complete.” However, for nonprofit organizations and governmental bodies eager to prevent a vulnerable population from ending up on the streets, the informal census does provide highly valuable information.  Two recent initiatives—very different from one another—offer inspiring answers. The most recent one, Le Christin, was designed by Atelier Big City (led by architects Anne Cormier, Randy Cohen, and Howard Davies) and inaugurated in 2024. Studios du PAS, on the other hand, was designed by Montreal firm L. McComber, and welcomed its first tenants in 2022. Both projects involved long-standing charities: the 148-year-old Accueil Bonneau, in the case of Le Christin, and the 136-year-old Mission Old Brewery for Studios du PAS. Le Christin was spearheaded, and mostly financed, by the Société d’habitation et de développement de Montréal (SHDM), a non-profit, para-municipal corporation created in 1988. Studios du PAS was first selected by the City of Montreal to be built thanks to the Rapid Housing Initiative (RHI) program run by the Canada Mortgage and Housing Corporation (CMHC). Le Christin also received a financial contribution from the CMHC towards the end of the process. Boldly coloured blind walls signal the presence of Le Christin in the center of a densely occupied city block, with entrance to the left along Sanguinet Stree. Le Christin Although sited in a very central location, near the buzzing St. Catherine and St. Denis streets, Le Christin is hard to find. And even when one suddenly spots two seven-storey-high walls, coloured lemon-zest yellow and mango orange, it’s difficult to figure out what they are about. A stroll along the tiny Christin Street finally reveals the front façade of this new facility, now home to some of Montreal’s most vulnerable citizens.  View of Le Christin’s modulated front façade. Galvanized steel panels at ground level add a soft touch while protecting the building from potential damage caused by snow plows. Le Christin is unique for a number of reasons. First among them is its highly unusual location—at the centre of a dense city block otherwise occupied by university buildings, office towers, and condo blocks. Until a few years ago, the site was home to the four-storey Appartements Le Riga. The Art Deco-style building had been built in 1914 by developer-architect Joseph-Arthur Godin, who was a pioneer in his own right: he was one of the first in Montreal to experiment with reinforced concrete structures, a novelty in the city at the time. A century later, Le Riga, by then the property of SHDM, was in serious need of repair. Plans had already been drafted for a complete renovation of the building when a thorough investigation revealed major structural problems. Tenants had to leave on short notice and were temporarily relocated; the building was eventually demolished in 2019. By that time, Atelier Big City had been mandated to design a contemporary building that would replace Le Riga and provide a “place of one’s own” to close to 150 tenants, formerly homeless or at risk of becoming so.    Le Christin – Site Plan and Ground Floor Plan The entire operation sparked controversy, particularly as Le Christin started to rise, showing no sign of nostalgia. The architects’ daring approach was difficult to fathom—particularly for those who believe social housing should keep a low profile.  The program, originally meant for a clientele of single men, gradually evolved to include women. In order to reflect societal trends, the architects were asked to design 24 slightly larger units located in the building’s east wing, separated from the rest of the units by secured doors. Thus, Le Christin is able to accommodate homeless couples or close friends, as well as students and immigrants in need. A tenants-only courtyard is inserted in the south façade. In order to provide the maximum number of units requested by SHDM, each of the 90 studios was reduced to 230 square feet—an adjustment from Atelier Big City’s initial, slightly more generous plans. In a clever move, an L-shaped kitchen hugs the corner of each unit, pushing out against the exterior wall. As a result, the window openings recede from the façade, creating a sense of intimacy for the tenants, who enjoy contact with the exterior through large windows protected by quiet Juliet balconies. Far from damaging the initial design, the added constraint of tightened units allowed the architects to modulate the building’s façades, creating an even stronger statement. On the unit levels, corridors include large openings along the south façade. Each floor is colour-coded to enliven the space; overhead, perforated metal plates conceal the mechanical systems. An extra floor was gained thanks to the decision to expose the various plumbing, electrical, and ventilation systems. Well-lit meeting rooms and common areas are found near Le Christin’s front entrance, along with offices for personnel, who are present on the premises 24 hours a day. Apart from a small terrace above the entrance, the main exterior space is a yard which literally cuts into the building’s back façade. This has a huge impact on the interiors at all levels: corridors are generously lit with sunlight, a concept market developers would be well advised to imitate. The adjacent exit stairs are also notable, with their careful detailing and the presence of glazed openings.  The fire stairs, which open onto the exterior yard at ground level, feature glazing that allows for ample natural light. Le Christin has achieved the lofty goal articulated by SHDM’s former director, architect Nancy Schoiry: “With this project, we wanted to innovate and demonstrate that it was possible to provide quality housing for those at risk of homelessness.” The low-slung Studios du PAS aligns with neighbourhood two-storey buildings. Studios du PAS In sharp contrast with Le Christin’s surroundings, the impression one gets approaching Studios du PAS, 14 kilometres east of downtown Montreal, is that of a small town. In this mostly low-scale neighbourhood, L. McComber architects adopted a respectful, subdued approach—blending in, rather than standing out.  The project uses a pared-down palette of terracotta tile, wood, and galvanized steel. The footbridge links the upper level to shared exterior spaces. The financing for this small building, planned for individuals aged 55 or older experiencing or at risk of homelessness, was tied to a highly demanding schedule. The project had to be designed, built, and occupied within 18 months: an “almost impossible” challenge, according to principal architect Laurent McComber. From the very start, prefabrication was favoured over more traditional construction methods. And even though substantial work had to be done on-site—including the installation of the roof, electrical and mechanical systems, as well as exterior and interior finishes—the partially prefabricated components did contribute to keeping costs under control and meeting the 18-month design-to-delivery deadline. Les Studios du PAS The building was divided into 20 identical modules, each fourteen feet wide—the maximum width allowable on the road. Half the modules were installed at ground level. One of these, positioned nearest the street entrance, serves as a community room directly connected to a small office for the use of a social worker, allowing staff to follow up regularly with tenants. Flooded with natural light, the double-height lobby provides a friendly and inclusive welcome. The ground level studios were designed so they could be adapted to accommodate accessibility needs. Some of the ground floor units were adapted to meet the needs of those with a physical disability; the other units were designed to be easily adaptable if needed. All studio apartments, slightly under 300 square feet, include a full bathroom, a minimal kitchen, and sizeable storage space hidden behind cabinet doors. Most of the apartments include a small exterior alcove, which provides an intimate outdoor space while creating a subtle rhythm along the front façade. Inside the studio units, storage cupboards for clothes and belongings were added as an extension of the kitchen wall. Conscious of the tradition of brick residential buildings in Montreal, yet wanting to explore alternate materials, the architects selected an earth-toned terracotta tile from Germany. The 299mm x 1500mm tiles are clipped to the façade, allowing for faster installation and easier maintenance. All units enjoy triple-glazed windows and particularly well insulated walls. A high-performance heat pump was installed to lower energy demand—and costs—for heating and cooling needs. Wood siding was used to soften the upper-level balconies, which provide protected outdoor spaces for residents.   Pride and Dignity Le Christin and Les Studios du PAS have little in common—except, of course, their program. Architecturally speaking, each represents an interesting solution to the problem at hand. While Le Christin is a high-spirited, flamboyant statement, Studios du PAS is to be praised for its respectful attitude, and for the architects’ relentless search for interesting alternatives to traditional construction norms. Atelier Big City is one of few firms in Canada that has the guts—and the talent—to play with bold colours. Decades of experimentation (not just with public buildings, but also within their own homes), led up to Le Christin, which is perhaps their strongest building to date. Their judicious choices of colour, brick type, and materials transmit a message of pride and dignity. Both projects demonstrate enormous respect and generosity to their residents: they provide architecture that treats them not as an underclass, but as regular people, who need the stability of dignified housing to start rebuilding their lives.

The tower takes shape as two sets of overlapping cylinders, clad with prefabricated panels intended to evoke clouds. PROJECT The Butterfly + First Baptist Church Complex ARCHITECT Revery Architecture PHOTOS Ema Peter When you fly into Vancouver, the most prominent structure in the city’s forest of glass skyscrapers is now a 57-storey edifice known as the Butterfly. Designed by Revery Architecture, the luxury residential tower is the latest in a string of high-rises that pop out of the city’s backdrop of generic window-wall façades.  The Butterfly’s striking form evolved over many years, beginning with studies dating back to 2012. Revery principal Venelin Kokalov imagined several options, most of them suggesting a distinct pair of architectural forms in dialogue. Renderings and models of the early concepts relay a wealth of imagination that is sorely missing from much of the city’s contemporary architecture, as land economics, zoning issues, and the profit motive often compel a default into generic glass-and-steel towers. The earliest concepts look starkly different—some evoke the Ginger and Fred building in Prague (Frank Gehry with Vlado Milunić, 1996); others the Absolute Towers in Mississauga (MAD with Burka Varacalli Architects, 2009). But one consistent theme runs through the design evolution: a sense of two Rilkean solitudes, touching.  On each floor, semi-private sky gardens offer an outdoor place for residents to socialize. Client feedback, engineering studies, and simple pragmatics led to the final form: two sets of overlapping cylinders linked by a common breezeway and flanked by a rental apartment on one side and a restored church doubling as a community centre on the other. The contours of the floorplan are visually organic: evocative of human cells dividing. The roundness of the main massing is complemented by curvilinear balustrades that smoothly transform into the outer walls of each unit. It’s an eye-catching counterpoint to the orthogonality of the city’s built landscape. The two adjacent buildings—built, restored, and expanded as part of a density bonus arrangement with the city—help integrate this gargantuan structure with the lower-rise neighbourhood around it.  The Butterfly is a high-end, high-priced residential tower—one of the few typologies in which clients and communities are now willing to invest big money and resources in creative, visually astonishing architecture. That leads to a fundamental question: what is the public purpose of a luxury condo tower?  A public galleria joins the renovated First Baptist Church to the new building. Serving as a welcoming atrium, it allows for community access to the expanded church, including its daycare, full gymnasium, multi-purpose rooms, overnight emergency shelter, and community dining hall equipped with a commercial kitchen. Whatever one feels about the widening divide between the haves and have-nots in our big cities, this building—like its ilk—does serve several important public purposes. The most direct and quantifiable benefits are the two flanking buildings, also designed by Revery and part of the larger project. The seven-storey rental apartment provides a modest contribution to the city’s dearth of mid-priced housing. The superbly restored and seismically upgraded First Baptist Church has expanded into the area between the new tower and original church, and now offers the public a wider array of programming including a gymnasium, childcare facility, and areas for emergency shelter and counselling services for individuals in need.  The church’s Pinder Hall has been reimagined as a venue for church and community events including concerts, weddings, and cultural programming. The Butterfly’s character is largely defined by undulating precast concrete panels that wrap around the building. The architects describe the swooping lines as being inspired by clouds, but for this writer, the Butterfly evokes a 57-layer frosted cake towering above the city’s boxy skyline. Kokalov winces when he hears that impression, but it’s meant as a sincere compliment. Clouds are not universally welcome, but who doesn’t like cake?  Kokalov argues that its experiential quality is the building’s greatest distinction—most notably, the incorporation of an “outdoors”—not a balcony or deck, but an actual outdoor pathway—at all residential levels. For years the lead form-maker at Bing Thom Architects, Kokalov was responsible for much of the curvilinearity in the firm’s later works, including the 2019 Xiqu Centre opera house in Hong Kong. It’s easy to assume that his forte and focus would be pure aesthetic delight, but he avers that every sinuous curve has a practical rationale.  The breezeways provide residents with outdoor entries to their units—an unusual attribute for high-rise towers—and contribute to natural cooling, ventilation, and daylight in the suites. Defying the local tower-on-podium formula, the building’s façade falls almost straight to the ground. At street level, the building is indented with huge parabolic concavities. It’s an abrupt way to meet the street, but the fall is visually “broken” by a publicly accessible courtyard.   The tower’s layered, undulating volume is echoed in a soaring residential lobby, which includes developer Westbank’s signature—a bespoke Fazioli grand piano designed by the building’s architect. After passing through this courtyard, you enter the building via the usual indoor luxe foyer—complete with developer Westbank’s signature, an over-the-top hand-built grand piano designed by the architect. In this case, the piano’s baroquely sculpted legs are right in keeping with the architecture. But after taking the elevator up to the designated floor, you step out into what is technically “outdoors” and walk to your front door in a brief but bracing open-air transition.  The main entrance of every unit is accessed via a breezeway that runs from one side of the building to another. Unglazed and open to the outside, each breezeway is marked at one end with what the architects call (a little ambitiously) a “sky garden,” in most cases consisting of a sapling that will grow into a leafy tree in due course, God and strata maintenance willing. This incorporation of nature and fresh air transforms the condominium units into something akin to townhouses, albeit stacked exceptionally high.  The suites feature a custom counter with a sculptural folded form. Inside each unit, the space can be expanded and contracted and reconfigured visually—not literally—by the fact that the interior wall of the secondary bedroom is completely transparent, floor to ceiling. It’s unusual, and slightly unnerving, but undeniably exciting for any occupants who wish to maximize their views to the mountains and sea. The curved glass wall transforms the room into a private enclave by means of a curtain, futuristically activated by remote control. The visual delight of swooping curves is only tempered when it’s wholly impractical—the offender here being a massive built-in counter that serves to both anchor and divide the living-kitchen areas. It reads as a long, pliable slab that is “folded” into the middle in such a way that the counter itself transforms into its own horseshoe-shaped base, creating a narrow crevice in the middle of the countertop. I marvel at its beauty and uniqueness; I weep for whoever is assigned to clean out the crumbs and other culinary flotsam that will fall into that crevice.  A structure made of high-performance modular precast concrete structural ribs arcs over a swimming pool that bridges between the building’s main amenity space and the podium roof. The building’s high-priced architecture may well bring more to the table than density-bonus amenities. On a broader scale, these luxe dwellings may be just what is needed to help lure the affluent from their mansions. As wealthy residents and investors continue to seek out land-hogging detached homes, the Butterfly offers an alternate concept that maintains the psychological benefit of a dedicated outside entrance and an outrageously flexible interior space. Further over-the-top amenities add to the appeal. Prominent among these is a supremely gorgeous residents-only swimming pool, housed within ribs of concrete columns that curve and dovetail into beams.   The ultimate public purpose for the architecturally spectacular condo tower: its role as public art in the city. The units in any of these buildings are the private side of architecture’s Janus face, but its presence in the skyline and on the street is highly public. By contributing a newly striking visual ballast, the Butterfly has served its purpose as one of the age-old Seven Arts: defining a location, a community, and an era.

Architect: PPAALocation: Santiago de Querétaro, MexicoCompletion Date:2024Sometimes all it takes to deliver a successful project is a client who is willing to take a chance. When a past residential customer approached Pablo Pérez Palacios, principal of his eponymous firm, Pérez Palacios Arquitectos Asociados (PPAA), about an expansion of an office for the premium dairy company Lyncott in Santiago de Querétaro, Mexico, the architect suggested something unusual: a modular structure made entirely of cross-laminated timber (CLT). In Mexico, as Pérez Palacios explained to AN, concrete is considered the de facto building material. In fact, when the client asked for examples of similar wood construction in Mexico, there simply weren’t any. Adding to the complexity, the architect advocated to use a polycarbonate system by the manufacturer Danpal as the facade. Essentially, Pérez Palacios was proposing a never-used (in Mexico) structure clad in a translucent envelope that would obscure most views from the interior offices. In theory, it sounded crazy. The building’s exterior is clad entirely in Danpal, a polycarbonate system, and connected to a cross-laminated timber frame. (Fabian Martínez) Fortunately, the client, who had recently risen to the top spot in the family-owned company, engaged with Pérez Palacios. At first, the executive told him, “I’m sure you won’t take this project, because it’s in an industrial park with zero budget,” recalled the architect, a past AN Interior Top 50 honoree. “I told him I’d take the project, without telling him that in the back of my mind, I knew I was going to do it out of wood.” Pérez Palacios had to overcome two hurdles from the outset: how to keep costs down despite CLT being a more expensive material than concrete and finding workers who could deliver on the construction. Fortunately, Vigalam, a company that manufactures prefabricated wood structures was located in the same office park as Lyncott, virtually eliminating shipping costs and simplifying the contracting. The team enlisted representatives from Danpal to install the facade system. The company sent a team to place and attach the panels, an exacting process that involves a clip to which a frame is attached and which then receives the polycarbonate pieces. Inside, the framing systems of the CLT and Danpal meet. (Fabian Martínez) Pérez Palacios is either a sly salesman or an eccentric designer—or both—but he managed to pull off one of Mexico’s first all-CLT projects and one of the most striking industrial buildings in recent memory. PPAA connected the thin 10,900-square-foot office expansion to an existing structure. Here the light, efficient addition contrasts the heavy, inefficient existing conditions; Pérez Palacios explained that the original steel and concrete building operates 24 hours a day to support the dairy plant and relies on artificial light. As PPAA captioned an Instagram post about the project, “This new intervention addresses the challenge of balancing the industrial character of the context with a serene and conscious environment focused on connecting with nature.” The translucent facade allows light into the offices and exposes the wood frame from the exterior. (Fabian Martínez) One of the most intriguing aspects of the facade is its lack of transparent glass, though Pérez Palacios noted that there are windows along the side of the building facing the dairy plant. “When you’re in an office, you’re not looking at the view. You are looking at a screen,” he said. “To create an atmosphere with natural light, it’s super nice if you’re going to be sitting at a computer for eight hours a day.” Besides, he added: “There’s nothing to see outside. It’s an industrial park.” The offices are bathed in light via the translucent facade. (Fabian Martínez) PPAA has completed two translucent projects previously: a now-finished office building in China that employed fabric and a housing prototype for a 2022 exhibition at Crystal Bridges Museum in Arkansas. “It was our interpretation of an affordable housing project—and we used Danpal!” Pérez Palacios exclaimed. Still, the dairy building project is the first time he put his theories about Danpal into practice. “We created this translucent envelope that allows people to work in natural light all day long,” Pérez Palacios explained. “It has solar capacities; it blocks the sun rays. It requires zero maintenance and protects the interior structure.” PPAA used wood for the entire structure, including beams, columns, and ceilings. (Fabian Martínez) Efficiency was part of the selling point to Lyncott, whose leader worried about the building’s lightness. “I had to tell him, ‘Don’t worry, it won’t blow away,’” Pérez Palacios recalled with a laugh. He went on to connect the agricultural aspects of the client’s business to the sustainability of building with these methods. The wood reduces the structure’s carbon footprint, and an all-glass facade would have run up the air-conditioning bills. Instead, Lyncott’s new building redirects the sun, part of the reason it has become something of an attraction in Mexico. Pérez Palacios foresees bringing students for site visits, and Danpal has shown the site to potential clients. PPAA has even sold the idea of mass timber construction to a skeptical audience: Now the firm has two more wood projects in the pipeline.

Today, we use physics, mathematics, and engineered design to reimagine and scale these crafted artifacts for future-oriented large structures," said Sigrid Adriaenssens.The "Arcade" is a vaulted structure that is 7.5 meters long and was created using three different roof and floor systems techniques. The "Alternative Skies Archive" below it employs traditional crafts to examine the relationship between natural materials and collective building knowledge.The "Arcade" has three full-scale vaulted systems and was created by Sigrid Adriaenssens and Wesam Al Asali as part of their joint project "Structural Crafts." These include a classic interlaced timber shell that combines attractive geometry and structural performance, a segmented tile vault that was created as a prefabricated modular system utilizing panelized building techniques, and a woven willow roof that was put together with the use of Augmented Reality tools. More than just a structural component, the suspended Arcade is a spatial representation of how design and production technologies convert implicit knowledge—such as patterns, pressures, and material intelligence—into architectural form.Two parallel cabinets frame the "Alternative Skies Archive" beneath the Arcade, inviting viewing and education. This learning environment was created in collaboration with the design laboratory (d-Lab) at the IE School of Architecture and Design under the direction of Romina Canna. Students from the Bachelor of Architectural Studies program collaborated with IWLab, a practice that Al Asali co-founded. From Syria's corbelled domes to Egypt's clay dovecotes, the exploring area showcases a variety of regional roofing customs, showcasing the inventiveness and resourcefulness of place-based methods. The "Archive" is an example of how local expertise and modern creativity may coexist to create sustainable, well-founded architecture.Romina Canna highlighted the alignment between the project and the IE School of Architecture and Design d-Lab's mission: "At our design laboratory, we explore design as a means of connecting disciplinary knowledge with other realms of meaning and production. In "Alternative Skies", we developed a narrative that reveals both existing and potential links between traditional knowledge and techniques, material intelligence, and design innovation."Intelligens Natural Artificial Collective is the theme of Carlo Ratti's 19th International Architecture Exhibition at Venice Architecture Biennale, which runs from May 10 to November 23. The show, which is organized around four sub-themes—Transdisciplinarity, Living Lab, Space for Ideas, and Circularity Protocol—aims to connect technology, nature, and teamwork.Ratti highlights that creativity, interdisciplinary collaboration, and inclusivity are essential for the advancement of architecture in the modern day. This edition investigates how architecture might use various forms of intelligence to adapt to an environment that is changing quickly. By showcasing the potential for incorporating community handicraft and natural intelligence into modern architectural thought, "Alternative Skies" significantly advances this discussion.With support from the Princeton Institute for International and Regional Studies, IE School of Architecture and Design, Research Office IE University, and IE Foundation, "Alternative Skies" is able to participate in the 19th International Architecture Exhibition of La Biennale di Venezia.PlanVault boards tileVault boards timberVault boards willowThe 19th International Architecture Exhibition will take place from 10 May to 23 November 2025 at the Giardini, the Arsenale and various venues in Venice, Italy.Find out all exhibition news on WAC's Venice Architecture Biennale page. Exhibition factsConcept: Wesam Al AsaliDesign team: Wesam Al Asali, Sigrid Adriaenssens, Romina Canna, Robin Oval.Authorial Collaborators IWLab: Marah Sharabati, Joelle Deeb, Sadek Jooriahd-Lab (IE School of Architecture and Design): Marta Garcia Salamanca, Malena Gronda Garrigues, Michaela Zavacká, Alaa Belal, Hayk Areg Khachikyan Supported by: Princeton Institute for International and Regional Studies, IE School of Architecture and Design, Research Office IE University, IE FoundationTechnical Collaborators: Salvador Gomis Aviñó (CERCAA), Angel Maria Martín López (La Escuela de Carpintería de lo Blanco de Narros del Castillo), Carlos Fontales Ortíz, ETSAMaderaAknowledgments to: Alejandro García Hermida, Kinda Ghannoum, Alessandro Dell'Endice, IE University Fab Lab, Maintenance Team IE UniversityAll images © Luis Díaz Díaz.All drawings © Wesam Al Asali.> via IE University

Willis Building, 1975 Source:Nigel YoungWillis Building by Foster + Partners Located in Ipswich, Foster + Partners’ office for insurance company Willis Faber & Dumas features a swimming pool, roof-top garden and restaurant. Often used as an example of early high-tech buildings, the office hosts around 1,300 staff across open-plan offices and flexible spaces, which were said to be untraditional at the time. These spaces are spread over three floors connected by escalators which were innovative in the 1970s, particularly in offices. Outside, in contrast, the building reinforces rather than confronts the urban grain, with its free-form plan and low-rise construction responding to the scale of surrounding buildings, while its curved façade maintains a relationship to the medieval street pattern.Advertisement Read more about the project in AJ Buildings Library. Sainsbury Centre, 1978 Source:Ken KirkwoodSainsbury Centre by Foster + Partners This School of Fine Art and art centre was designed to house a collection gifted to the University of East Anglia by Sir Robert and Lady Sainsbury. The design incorporates structural and service elements within the double-layer walls and roof. Within this shell is a free-flowing sequence of spaces that incorporates a conservatory reception area, coffee bar, exhibition areas, the Faculty of Fine Art, senior common rooms and a restaurant. Full-height windows at either end of the structure allow the surrounding landscape to form a backdrop to the exhibition and dining areas, while aluminium louvres, linked to light sensors, line the interior to provide an infinitely flexible system for the control of natural and artificial light.

The triangular atria, which have the planning benefit of leaving the office spaces almost rectangular, also provide greater daylight penetration.

Millau Viaduct, 2004 Source:Nigel YoungMillau Viaduct by Foster + Partners Designed with engineer Michel Virlogeux, the 2.46km-long cable-stayed bridge formed a crucial transport link in the Paris to Barcelona motorway across a valley in south-west France. It has the highest elevated roadway in the world, with its deck set 270m above the River Tarn. Supported on seven concrete piers of varying heights, the bridge has a 3 per cent slope from south to north to encourage drainage. A gentle curve as the bridge approaches the northern plateau helps wind resistance. Both these factors work aesthetically too, accentuating the sense that the structure is tailored precisely to a specific site. Each of its sections spans 342m and its columns range in height from 75m to 245m, with the masts rising a further 90m above the road deck. Find out more in AJ Buildings Library. Wembley Stadium, 2007 Source:Nigel YoungWembley Stadium by Foster + Partners A collaboration with sports design specialists Populous, Foster + Partners’ arena replaced the old Wembley Stadium, which was one of the most important sports venues in Britain. With a 90,000 capacity and a retractable roof, the new structure was designed to maximise spectator enjoyment and retain the stadium’s iconic status The geometry and steeply raked seating tiers ensure that every spectator in the 90,000-capacity stadium has an unobstructed view of the pitch. The stadium has a retractable roof that allows the turf to get sufficient sunlight and air, while in poor weather it can be closed to cover the entire seating bowl. The roof is supported structurally by a 133m-high arch that towers above the stadium, providing an icon and a new London landmark. Read more about Wembley Stadium in AJ Buildings Library.

The 500m², single-storey building is focused around a garden. At the eastern side adjoining the car park the garden is broken up into small courtyards, offering private spaces leading from each of the centre’s counselling rooms. To the west, the garden is more open and offers a threshold between the street and the centre. Meanwhile, a greenhouse with a faceted glass façade echoes the building’s triangular rooflights. Naturally illuminated by these triangular rooflights, the building is supported by lightweight timber lattice beams. These beams act as natural partitions between different internal areas, visually dissolving the architecture into the surrounding gardens. Discover more about this project in AJ Buildings Library. Bloomberg London, 2017 Source:Nigel YoungBloomberg HQ by Foster + Partners Foster + Partners’ £1 billion European HQ for business news giant Bloomberg is ambitious, accomplished and lavish. The fins, 117 in total, are the building’s way of ‘breathing’, with each section opening or closing depending on exterior conditions. This allows air to flow into the building while keeping external noise to a minimum, as well as filtering incoming air. Chunky stone corners and shear walls form part of the sandstone façade, with muscular poché sections fitted with thermal doors allowing air to circulate through the structure.
