Stuttgart's cultural mile consisting of the Staatsgalerie, Württemberg State Library and Stadtpalais is to be extended to Wilhelmsplatz with the addition of the House for Film and Media. The new building is designed as a cultural and educational institution with an impact beyond the city limits. The appearance of the building is largely determined by the experience of the supporting structure.
The nine-storey building with external dimensions of approx. 38 x 38 m consists of a total of seven rising storeys and two basement storeys. The two basement storeys are an economical and robust reinforced concrete construction that acts as a rigid basement box, transferring all incoming loads evenly into the ground. All upper floors are designed in a lightweight steel and timber construction, with the main load-bearing elements consisting of steel columns and steel beams with suspended timber ribbed ceilings and slabs. The building is characterized by the generous cantilevers of the top five floors in two building directions. These are realized via a circumferential steel truss. As a lightweight construction, the truss structure uses the top two storeys as the static height and serves as a low-deformation and economical suspension system for the cantilevered storey ceilings. All structural elements are prefabricated to a high degree, are assembled quickly and with low emissions on site and can also be dismantled completely non-destructively. In terms of the circular economy, components can be completely reused or recycled with virtually no waste.
