Multi-Family House, Grossaffoltern


In Grossaffoltern in the Bernese Seeland, four apartment buildings with the new TS3 technology are being built. This is the world's first residential development with this innovative technology.

The Project

The three-storey residential development with 20 comfortable apartments is located in Hollerenacher in Grossaffoltern between Bern and Biel. The ground floor and the first floor are each occupied by two apartments, on the top floor a penthouse apartment with a panoramic view was built. 

The sustainable timber buildings in Grossaffoltern are the first in the world to use TS3 technology. This means that the floor slabs of the buildings consist of large-format cut cross laminated timber panels glued to the front using TS3 technology. This allows building users maximum flexibility of use in addition to a pleasant room climate. 

The construction method

Prefabricated wooden elements were erected on the concreted floor slabs. The 13 glued laminated timber panels, each 2.5 metres in size, were glued at the front of the building site to form the floor slabs. A total of 2300 square metres of floor slabs were glued and installed in the four apartment buildings. 

The challenges

The impregnation of the end faces of the cross laminated timber panels posed a major challenge. For this purpose, a tent with a construction crane was erected near the construction site. In this way, the boards could be prepared and precisely glued to floor slabs at the construction site. 

- Cross laminated timber 230 m³
- Round timber supports 12 pieces

- Joints with TS3 technology
