The initial situation

In order to gain more (school) space, the International School Zurich in Wädenswil decided to extend its school building by an additional floor. For weight reasons, the outer walls and the roof were made of timber elements. The load-bearing interior walls are made of sand-lime brick    


The implementation

A special feature of this building was the fact that weight could only be transferred to the solid exterior walls at very specific points. Due to the high span widths of the roof and the window arrangement with corner windows, an interception structure was created in the roof edge area, which was implemented with kerf beams. Notable are the large roof windows, which were another challenge to the load-bearing concept.
