The Ibach school complex in Schwyz is to be refurbished and extended to provide space for 10 classes each in cycles 1 and 2, shared facilities, after-school care and two sports halls. The redevelopment will be based on the «3MAL3» design by the team led by Ernst Niklaus Fausch Partner, which won first prize in the competition. The project envisages a new three-storey school building, whilst the existing Muota school building will be demolished. The new building combines a double sports hall sunk into the ground with Cycle 2 classrooms arranged above it. The existing buildings will be modernised and interconnected via walkways and connecting structures. The former Christophorus sports hall will be organised over two storeys using an integrated timber structure and will house the after-school care facilities as well as the multi-purpose hall and music room. «The proposal organises the uses optimally, allows for great future flexibility on various levels and impresses with its understated architectural expression, both in the new building and in the targeted extensions to the existing structures,» said the jury in its praise of the winning project.
The structural concept for the new Muota building, developed by LÜCHINGER MEYER PARTNER, comprises three distinct layers: the basement box structure made of in-situ concrete, the ground floor with the support platform above the sports hall, and the two-storey timber structure resting on top of this. The span of the open ground floor is spanned by steel beams resting on concrete columns. A lightweight concrete slab spans between the beams and in the entrance area, which also provides the necessary sound insulation. The timber structure is based on a column grid, which ensures the greatest possible flexibility of use. The slabs are simply supported and rest on timber joists along the façade and the circulation area. Thanks to the reduced slab construction height in the circulation area, building services can be routed via the main beams between the ribs.
