A new building was added to the existing art depot of the Froehlich Foundation near Stuttgart in order to be able to display more works from the art collection. It is directly adjacent to the existing building to the south of the foundation building. The exhibition space in the new building is distributed over three floors. The ground floor serves as the main area for the exhibition and, due to a high ceiling, also provides space for large artworks. Next to the spacious room are exhibition spaces, with no exposure to daylight, designed mainly for fragile objects of art. An open staircase leads to the upper floor, where a conference room is located behind a set-back glass facade. Technical rooms and a storage area as well as an exhibition room are in the lower level.
The initial idea for the roof was the concept of a floating cloud above the building. This evolved into a monocoque construction during the design process, which breaks down the actual load-bearing behavior into the elements of a structural concept. The flow of forces should remain comprehensible. The result is a solid structure with exposed concrete walls. On the upper floor, the solid structure is broken up by a load-bearing steel façade construction. The free-formed roof made of wood floats above it.
