Johnsonhaus, Köniz

The project
The building in the form of a quarter circle has dimensions of approximately 90 x 14 x 17 m. In it 32 rental apartments between 3½ and 5½ rooms were created. Furthermore, the building includes 3 loft apartments as well as 820 m² of retail, service and commercial space and 26 parking spaces. The residential and commercial building of the Stanley Thomas Johnson Foundation in Köniz won the "Recognition Region Mitte" at the Prix Lignum 2015. The Prix Lignum is awarded every three years in the five major regions of Switzerland for pioneering timber construction projects. Timbatec was allowed to ensure all timber engineering services and fire protection for this showcase project.

The construction
The timber construction starts from the ceiling above the first floor (prestressed reinforced concrete ceiling) and consists of 4 full floors. Wood-concrete composite ceilings were installed between the load-bearing apartment partition walls. The roof is also a wood-concrete composite ceiling, the outermost layer of which is formed by extensive greenery. The building is braced via the superimposed concrete as well as through the staircase cores into the foundation.
