These are only a few of the speculative designs architects throughout the years have developed in an attempt to push the boundaries of the discipline forward and respond to the many challenges the global built environment is facing. From early drawings such as Giovanni Battista Piranesis Imaginary Prisons and Jean-Jacque Lecques Gate of a Hunting-Ground, speculative or paper architecture has been a subject of great experimental release since the 18th century.Even though they stay only on paper, these designs hold such enticing qualities not only due to the impeccable drawings that represent them but also for the fictional stories they tell. Through them, design and construction methods are questioned, and real-world problems are solved, thus becoming a source of inspiration for architects throughout the world. Especially during the 1960s-1970s, avant-garde architects spawned some of the most influential architectural movements of that time.Jean-Jacques Lequeucreator QS:P170,Q1684923,Lequeu Tor eines Jagdgelaendes Projekt, marked as public domain, more details onWikimedia CommonsArchigramPossibly the most well-known group of speculative architects, Archigrams unbuilt projects were developed after WWII, in an attempt to reevaluate the way in which people lived in urban centers. Plug-in City and Walking City were some of their most provocative projects, utilizing hypothetical technology to create energy efficient structures that introduced concepts such as movable cities, modular architecture and even nomadic living.Lebbeus WoodsGeomagnetic Flying Machines. Estate of Lebbeus WoodsDuring his career Lebbeus Woods focused on architectural theory and experimentation and co-founded the Research Institute for Experimental Architecture. Although his designs were unshackled by the constraints of the real world, i.e. finance, build-ability and technology, his work deals greatly with existing issues such as rebuilding post-war cities and architecture as a defense mechanism towards political upheavals. The Sarajevo Window for example, is a proposal for a wall and window repair after the Bosnian capital underwent terrorist attacks in the 1990s.Gaetano Pesce View this post on InstagramA post shared by Gaetano Pesce (@gaetano.pesce)The Italian architect and designer and his project the Church of Solitude addressed immigration issues and a corporate way of living. When experiencing New York in the 1970s, he witnessed large groups of people living together in helter-skelter conditions and thus developed the concept of an underground church fit for introspection, contemplation and a retreat from the citys institutional culture. Pesces excavated landscape became a refuge underneath the imposing, capitalist Manhattan skyscrapers.We are now a couple of decades later and still; paper architecture hasnt lost its allure for architects. There have been countless speculative proposals, breathtaking drawings and models as well as an abundance of theoretical and contextual writings that reveal that intent behind these designs.CJ Lim View this post on InstagramA post shared by cj lim IMAGINARIUM (@cjlimimaginarium)Food City is CJ Lims most recent project, in which he positions food in the core of national and local governance and influence the way in which a city is both spatially and functionally organized. The architect creates a hypothetical case study showcasing how a secondary environmental/food infrastructure can operate as a sustainable stratum over the city of London.Bryan Cantley View this post on InstagramA post shared by Bryan Cantley (@bcantl3y)Machno-morphic is one of the characterizations that vividly describes Bryan Cantleys work, which is comprised of speculative drawings that reflect upon the remains of mechanical realities within the landscapes of Southern California. He delves into the regions folklore, which mixes dreams of a suburban peace with Spanish Colonialism and mountainous landscapes, proposing future mechanical forms (instruments) that investigate, critique and oftentimes compliment the western industrial setting.Perry Kulper View this post on InstagramA post shared by Perry Kulper (@pkulper)Perry Kulpers proposals reach implausible dimensions. His drawing practices explore new ways of immersive design, investigating how architecture interacts with its cultural environment. Beyond inventing new modes of architectural representation, Kulper work looks at real places, landscapes and contexts and composes an array of possible and unexpected interactions between them.After exploring examples of paper architecture drawn in the past 50 years, it is safe to say that all these projects, albeit speculative, contain more than a dash of realism in them. They are practical interventions, situated in cities that face real-world challenges and propose solutions that tackle climate change, social housing, immigration, experiential design, food production, industrial production and so much more.At this point I want to borrow Lebbeus Woods quote stating that architecture is always constrained by the reality of technology. In other words, building all these paper architecture proposals is not impossible; it is merely a matter of whether technology can keep up with human imagination. The optimist in me believes that if we were to implement these designs with the same liberal manner in which they were conceived, i.e. breaking free from ulterior political and economic motives, architecture would truly and holistically impact our cities, our natural landscape, our resources and even reevaluate the (currently concrete) norms through which humans inhabit the planet.The latest edition of Architizer: The Worlds Best Architecture a stunning, hardbound book celebrating the most inspiring contemporary architecture from around the globe is now available.
