The new five-storey building and the extension were designed as a hybrid building in the lower office floors. The columns and ceilings are made of concrete and the non-load-bearing exterior wall elements of timber system construction. The floor has projections of up to 4.5 m. These are supported by individual glulam beams with dimensions of 400/1120 mm (brown). HBV-Floors are mounted between the glulam beams.
The trusses were prefabricated as complete elements in the factory of the neue Holzbau AG in Lungern. The beech construction node was integrated into the lower chord in such a way that it is no longer visible in the installed condition.
