The extension to the school building in Sutz-Lattrigen was built on the existing ground floor. This ground floor, however, was not designed for an additional story. Therefore, the loads from the first floor and the additional second story had to be designed as concentrated loads. In order to reduce weight, but also for educational and sustainability reasons, timber was used in the construction of the new building.

Indermühle Bauingenieure from the Swiss town of Thun was responsible for the timber engineering during the project phase, including from the preliminary project to the supervision of the final design. The firm also completed the 3D project planning on behalf of the timber construction company. The RFEM program was used for the structural analysis.
