The project proposes a mixed-use transformation that reinterprets the building as a “city within the city,” inspired by Le Corbusier’s Unité d’Habitation in Marseille. The existing structure is strategically reduced to its essential load-bearing concrete frame and floor slabs, preserving the structural skeleton while enabling radical spatial reconfiguration.\r\nPrefabricated timber modules are inserted and cantilevered between the reinforced-concrete columns, extending the usable floor area and introducing a warm, contemporary material contrast to the original façade. This intervention not only increases density and flexibility but also redefines the tower’s appearance, giving it a cosmopolitan and forward-looking architectural identity. The ground floor is conceived as an open and publicly accessible urban platform, activating the surrounding plaza and strengthening social interaction. Upper floors are redesigned as affordable and attractive living spaces for young residents, encouraging a diverse and vibrant community within the building.\r\nA newly designed park-like rooftop landscape provides recreational space and panoramic views over the city, enhancing environmental quality and urban connectivity. By combining structural preservation, modular timber construction, public programming, and residential reuse, the proposal demonstrates how high-rise retrofitting can generate social, ecological, and economic value simultaneously. The project positions adaptive reuse as a viable strategy for sustainable urban regeneration and architectural longevity.","lang":"eng"}],"title":"TreeTower","publisher":"Technische Hochschule Ostwestfalen-Lippe","year":"2020","department":[{"_id":"DEP1600"}],"extern":"1","language":[{"iso":"eng"}],"publication_status":"published","keyword":["Adaptive Reuse","Mixed-Use Development","High-Rise Transformation","City within the City","Modular Timber Construction","Prefabrication","Structural Preservation","Concrete Skeleton","Cantilevered Modules","Urban Regeneration","Public Ground Floor","Youth Housing","Rooftop Landscape","Sustainability","Social Impact","Ecological Design","Economic Viability","Cosmopolitan Architecture"],"date_updated":"2026-02-20T07:09:36Z","status":"public","citation":{"din1505-2-1":"<span style=\"font-variant:small-caps;\">Konschake, Leon</span>: <i>TreeTower</i>.
