  text: "This bachelor thesis explores the adaptive reuse of the former Telekom high-rise
    at Kesselbrink in Bielefeld, a vacant modernist office tower awaiting new purpose.
    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."
