Das Siedle Haus

The project is a museum building for the art collection of Gabriele and Horst Siedle. The ground floor of the building will be used as an exhibition space and meeting place, while the basement will house storage and technical facilities. A 3D model of the dilapidated residential building that was previously on the site was created with the help of photographic scans and transferred to the formwork planning. The new reinforced concrete structure is therefore an exact reproduction of the former building. The timber roof, which will be erected on top of this concrete structure, is modeled on the typical roofs of Black Forest houses, thus making a reference to the region and its history.

A beam structure with full cross-sections was chosen for the roof, which, as an irregularly supported girder grid, reproduces the shape of a traditional purlin roof. The concrete corpus of the cast of the historic house and the surrounding façade supports, which are integrated into the reinforced concrete structure, form the supports.

The façades were designed as a mullion and transom construction in a grid of 2.77 metres with triple insulating glazing. Pane heights of up to 13 metres were used. The direct connection to the load-bearing timber columns meant that additional steel or aluminium profiles were not required. This resulted in a particularly filigree construction despite the great heights. The external façade view is completely flush and free of protruding frame profiles.
