The hospital located in Stuttgart is one of the highest ranked medical centres in respect to efficiency and performance in Germany. The purpose of the redevelopment was to join the departments for internal medicine, surgery and neurology in terms of organisation and structure. In order to form a common entity new constructions have been added to the existing buildings, which had to be restructured, rebuilt and renovated in parallel. The site with a size of approximately 25.000 m² and is located in the city centre of Stuttgart, in the central zone of the mineral water protection area. The existing buildings must remain functional during construction phase as the construction measures take place parallel to continuous hospital activity. The new ten storey tall buildings were designed as steel-concrete skeleton structures with a very high demand for the integration of building equipment and for vibration behaviour. The reconstructions and conversions are aimed at reorganizing the use of building equipment. The design also comprises filigree steel-glass roofs located between existing and new buildings, as well as covering the inner courtyard of the new building.
