Adam Przywara is a Fellow of European Architecture Platform for 2024-25 season and was present at the 2024 LINA Conference: Community-Led Architecture in Sarajevo. He fosters, discusses and implements the idea of an ‘Atlas of Ruderal Architecture’. What can we learn from postwar architecture about building on a ruined planet? Following World War II in Europe, botanists such as R.S.R. Fitter in London, H. Sukopp in Berlin, and R. Kobendza in Warsaw studied the novel ecosystems emerging in the ruins of postwar cities. Their work documented ruderal nature (from the Latin "rudus" for rubble), exploring how plants adapted to environments radically transformed by the war. These studies were the first to engage with these unique ecosystems, which are now recognised for their crucial role in mitigating the effects of climate crisis in cities. A better understanding of ruderal architecture can greatly enrich our approach to sustainable design and circular construction by highlighting the realities of building with limited access to finances, fossil fuels, and raw materials. The 'Atlas of Ruderal Architecture' is a project based on my growing database of sites, people, and stories, as well as my experience as a curator, editor, and educator. Currently, I am working to expand the atlas into an itinerant exhibition and an online publication. This way, the project can serve as a tool for engaging architects, students, and the broader public in thinking with ruderal architecture about the possibilities of dwelling on a ruined planet.
