Reconstruction Restaurant Hirschenbad, Langenthal

The project
The Hirschenbad Inn, built in 1728, underwent a complete renovation and was expanded with a pavilion and a new kitchen. On September 26, 2019, the Hirschenbad restaurant was reopened after almost 18 months of renovation. All rooms were fundamentally renovated, energetically brought up to the latest state of the art and renovated with great attention to detail. In addition, a new environment was created with a beautiful garden and an associated pavilion. The cook's paradise was designed according to the most modern production methods and forms the basis for a regional, fresh cuisine.

The construction
The new pavilion in the outdoor area is worth highlighting. The oval shape is erected only on fan-shaped supports and features an opening on one side and a large canopy. The cross laminated timber roof spans an area of approximately 9m x 7m. The wooden panels were joined together to form a large surface using TS3 technology. The supports were clamped with glued-in threaded rods at the bottom. This allowed the construction without beams or supports in the middle of the pavilion.

The challenge
In renovations, load transfer is often a sticking point. By means of a truss construction on the first floor, the loads could be distributed from the floors above to the exterior walls.
