The Medical Centre Stuttgart is one of the highest-performance medical centres in Germany. The purpose of this project is to join the departments for internal medicine, surgery and neurology in terms of organisation and structure. This includes restructuring, conversion and renovation of existing buildings and addition of new constructions to form a common entity. The site has the size of approximately 25.000 m² and is located in the city centre of Stuttgart, in the core zone of the mineral water protection area. The existing buildings must remain functional during construction as the construction measures take place parallel to continuous hospital activity. The structures of the new 10-storey buildings were designed as ferro-concrete structures with a very high demand for the integration of building equipment and for vibration characteristics. The reconstructions and conversions are aimed at reorganising the use of building equipment. The design comprises filigree steel/glass structures between existing and new buildings, as well as over the inner yard of the new building.
