Preserving the facades’ distinctive grid structure was a primary objective. We installed high-quality aluminum-wood windows with integrated sunshades into the nearly square openings of the original staggered structure’s upper third and fourth floors. The windows’ warm bronze hue and prominent central mullion provide a striking contrast to the natural stone grid. An additional floor was added to Dornbusch 4, enhancing its proportions. We constructed a roof terrace atop the lower section of the building – a small green oasis amid the urban landscape. The new mullion and transom facade on the added level features full-height window elements that echo the grid pattern of the rest of the building. However, the metal pavilion-like structure sets it apart as a distinct addition, contrasting with the stone facade of the original building. Ground-floor shops welcome visitors with expansive glass surfaces that open up to the urban environment. The main entrance, positioned along the central axis of the Dornbusch facade, is flanked by a restaurant and a generously glazed lobby nestled in the building’s corner. Access to the underground parking garage is discreetly situated on a side street.
