The topic of this diploma thesis concentrates on an existing building located in Graz-Goesting. This particular edifice is abandoned and has been unused for several years. It was formerly owned by a shoe distributing company. In the mid-90's this company moved to another district and therefore this high-rise office building was closed. Abandoned for over a decade, it became a very distinctive and well-known construction in the 13th district. The main goal of this diploma thesis is to get rid of this current nuisance and to upgrade the site and its surrounding area. Due to the beneficial location and infrastructure, the project will include ownership and rental apartments and office spaces. In addition, the integration of an extended stay hotel has been researched, which can be attractive for long-term guests. These three main functions are not only integrated into the existing structure, but also added as new constructions, which are connected to the existing building. The Residential and Business Center in Goesting is faced with the difficult task to fit into the current environment and to create attractive residential apartments, hotel apartments, and offices.
