Friesenberg school ZM10 timber module extra storey

The modular pavilion has been part of the Friesenberg primary school complex in Zurich for 20 years. In the summer of 2019, it gained a third storey with an area of 253 m2, providing it with plenty of additional space. As GC, we designed, produced and built the school building extension based on the architectural concept by Bauart Architects and Planners.

The city of Zurich responded to the increased need for space at Friesenberg primary school using the proven Züri-Modular system. Two generations of the ZM10 have now been combined in the Friesenberg primary school pavilion. The consistent external design using three-ply vertical facade panels made of larch and anthracite-coloured Rockpanel cladding means that hardly any difference can be detected between the existing and the new modules. The enhanced modules in the newly added third storey provide two classrooms of 68 m2 each, a group work room of 33 m2, toilet facilities of 10 m2 and a technical room with an area of 5 m2. 

The return walls and ceilings are unusual from a construction perspective as they contain sheep’s wool as a formaldehyde absorber. The heating system in the building had to be reinforced and upgraded to meet the increased heat requirements. A new staircase added on top of the existing one provides access to the third floor.

The timber modules were prefabricated in our factory in six days, assembled on site in three days and fitted out in a further three to four weeks. The entire new storey was added during the summer holidays and therefore did not affect lessons in any way.
