Subject of the dissertation is the currently vacant building in Praterstraße 28, 1020 Vienna, which was initially planned by the architect Franz Xaver Ehmann in 1845 as an apartment house with a concentric recumbent courtyard and joining stables. In the 1970s, after several minor adjustments, the building was repositioned to 'Beauty Farm Hotel Aphrodite' - a hotel with spa and wellness facilities. However, a few years after the opening, the hotel closed again and the building has not been in use ever since. The aim of this thesis is an analysis of its inventory, its architectural and historical features, and the development of a concept for its potential revitalization. A careful handling of the existing structure, such as the preservation of the external appearance, is intended. The historical development of Praterstraße, once one oft the most splendid streets of Vienna, with its most important buildings is also briefly discussed in the thesis with the intention to provide an ap - proach for a new usability.
