The Wilhelm-Maybach school building in Stuttgart Bad Cannstatt is extended upwards by one floor which is visually distinct from the existing building. Extensive investigation of the existing structure revealed that the existing building, which dates from the 1950s, would not be able to support additional loads unless it was very substantially and expensively reinforced. For this reason, and in order not to impose any loads on the existing building, the structure of the extension is supported by an independent construction combining steel with reinforced concrete. This is achieved by placing slanting composite reinforced concrete supports in front of the existing building which support the steel construction and, through their slanting geometry, provide bracing against horizontal wind loads. These supports are based on in-situ concrete pile foundations. A large part of the facade of the new structure is glazed, thus providing an impressive view of the Neckar valley and Bad Cannstatt. The extension comprises six classrooms, two IT rooms, one study room for pupils as well as rooms for special subjects and preparation.
