The Project

The W52 Generation House actively promotes collaborative and intergenerational living. The attic has a co-living space with kitchen, as well as a furnished co-working space. Ecological and sustainable living are principles to which the residents of Generationenhaus W52 are committed. These also concern aspects of social behavior and conscious lifestyle.

The Construction

The structural implementation is based on the basic attitude described above and addresses, among other things, an ecological and energy-optimized construction method in wood. In the selection of building materials, attention is paid to their ecological sustainability and durability. Therefore, the use of TS3 technology is the logical consequence. The column-and-slab system does not require any steel or concrete at all. The TS3 slabs are painted white glazed, so the joints remain visible.

- Number of floors: 3 

- Gross floor area: 700 m²

- CLT: 140 m³

- TS3 technology: 280 linear meters of joints 

- Column grid: wall to wall
