Invitation to the first cellar made of timber



The BMW15 apartment building in Thun is an innovative showcase project: it is built on the first cellar made of wood in Switzerland, does not require heating and breaks new ground in digital planning. On September 1, we invite you to a guided tour together with the Initiative Holz BE.

The BMW15 apartment building in Thun is full of innovations. Therefore, together with the Initiative Holz BE, we invite architects and other interested people to visit the building. Presentations will highlight the opportunities and challenges identified in the collaborative 3D planning and construction of the house. Recently, the first apartment was inhabited, other apartments are still available for visitors to view. 

Program Event on 01 September 2021, meeting point 17.00

Mehrfamilienhaus in Thun

A lot of timber is visible on the outside and inside. The TS3 technology allows for a column-and-panel construction method. The TS3 joints remain visible in this project.

First cellar made of timber

What seemed impossible for a long time is now a reality: In Thun, the first apartment building with a basement made entirely of wood has been built. Houses without heating or air conditioning make an important contribution to climate protection. An even greater potential for energy savings lies in the choice of building materials. Timber is already widely used in building construction. The next step is to dispense with climate-damaging building materials such as steel and concrete - including in basements and floor slabs. In order for basements to be mass-produced from wood in the future, a number of research questions need to be clarified. A research project of the Bern University of Applied Sciences together with TS3, Timbatec and other business partners is currently addressing these questions. A start-up is to be founded from the group of research partners, which will be operationally active from 2023. 

Research project DeepWood

The DeepWood project refers to the future development of the BIM maturity level from level 2 to level 3 and faces the challenge of how to organize the collaboration of several users simultaneously in a common model. The BMW15 apartment building is the Living Lab for this research project with the Lucerne University of Applied Sciences and Arts and the Bern University of Applied Sciences.
