Courtyard Waberg, Adetswil

The project
Above Lake Pfäffikon in the municipality of Bäretswil, people in need of support live and work on the Waberg farm with a farming family. Timbatec was asked to contribute to the planning of the renovation in terms of timber construction engineering, fire protection, and building physics. The project comprises two sub-projects: on the one hand, the agricultural building complex was expanded to include a modern free-range barn for dairy farming and a new shed. The existing barn was converted; the ground floor now houses cloakrooms, an office, and the building services for the entire site, while the attic now serves as a hayloft. On the other hand, a replacement building with a guest apartment was constructed on the site of the old barn.

The construction method
Free range barn and shed: The agricultural building has half-timbered walls and a primary and secondary supporting structure in the form of a rafter-purlin roof. Conversion of the barn: This was insulated on the inside. A crane runway was integrated into the existing hayloft. Replacement building: This consists of a timber frame construction with curtain wall elements. The ceilings are solid wood ceilings with large-format cross-laminated timber (CLT) panels and a dry screed floor.

The challenge
In the hayloft, a strut frame construction enabled the installation of a crane runway into the existing supporting structure.
