The project focuses on the revitalization and redevelopment of the former courthouse in Riemergasse 7, Vienna. Since the relocation of the Commercial Court (2003), the building has been empty even though the solutions of conversion were often promised. Due to regular refurbishment, the listed building is relatively well preserved. Since the building is in the heart of downtown and has a very good configuration and appearance, a conversion of the building in a hotel would be possible. Not only the building would benefit from getting a new purpose of use but also the City of Vienna. The aim of this study would be to analyze the historic building and to work out a solution for the conversion of the building as a hotel.
