Lehndorfer Hof has been a significant building complex in the heart of Vienna-Floridsdorf. Built 1908 it was reconstructed following war damages and later further building-parts were added. The existing six different buildings varying in building age, conservation status, height and use shall be adapted and floors added.
The redevelopment and extension create a total gross floor area of 24,778 m² comprising 142 residential units, 6 offices, 16 shops and 76 underground parking spaces. In the existing floors, vacant office space is being converted into dwelling units. Added floors on levels four to seven house residential units.
The overall design intention is to harmonize the whole building complex and create one large-scale form. Added floors act as a visual bracket to unify varying building heights and align them with the neighboring buildings. Subsequent alterations of the 1950s facade, such as the bay window, are removed in order to achieve a continuous street appearance. The facade of the commercially used ground floor receives a uniformed configuration.
