Trom Swamp to Structure investigates how architecture can mediate between ecological restoration and contemporary building culture by re-establishing material, spatial, and social links between landscape and construction. Rooted in the theory of regenerative design, the project asks what architecture might become if it began not with a plan, but with a plant—if building were understood as cultivation and inhabitation as participation. The thesis focuses on paludiculture, the wet cultivation of rewetted peatlands, as a systemic alternative to extractive land use and carbon-intensive construction practices.Situated in the Berlin–Brandenburg region, where over ninety percent of peatlands remain drained and are a major source of CO₂ emissions, the project positions rewetted wetlands as ecological infrastructures and sources of regional value creation. Cattail, a rapidly growing wetland plant, forms the basis of a circular material chain: cultivated on restored peatlands, processed into insulation and construction panels, and applied architecturally within the project itself.This material cycle is anchored by a cattail-panel factory located along the River Spree in Berlin-Kreuzberg, embedded within an industrial waterfront context. The factory operates as both a productive and pedagogical space, linking landscape, labour, research, and public life. A meandering mixed-use building complements the industrial core, housing education spaces, research labs, and temporary housing, while maintaining an open ground plane that reintroduces wetland conditions into the dense urban fabric.Through the integration of ecological, technological, and social systems—particularly water management, material production, and collective use—the project proposes architecture not as an endpoint, but as part of a regenerative metabolism. Ultimately, From Swamp to Structure envisions a building culture grounded in local ecologies, material knowledge, and shared stewardship of landscapes.
