Tour of the house full of innovations



Due to high demand, the HOLZarchitekTOUR will stop again in Thun at BMW15 - a multi-family house full of innovations. On October 21, together with the Initiative Holz BE, we invite you to the guided tour.

The multi-family house will be shown to architects and other interested persons on October 21. In short lectures you will learn many interesting details about the construction and later you can visit the house during a guided tour.

BMW15 in Thun

A lot of wood 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 wood  

What seemed impossible for a long time is now a reality: Thun is home to the first apartment building with a basement made entirely of wood. 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. 

Wood 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 Timbatec, TS3 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. 

DeepWood research project

The DeepWood project refers to the future further development of the BIM maturity level from Level 2 to Level 3 and faces the challenge of how the collaboration of several users can be organized 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.

BMW15 in Thun

The 25-meter-long and eight-meter-wide wooden building stands on the basement with cross-laminated timber panels and is accompanied by an Innosuisse research project together with the Bern University of Applied Sciences BFH AHB Biel.
