The existing secondary school building from the 1970s requires a complete renovation. The structure, made of steel, is flexible and remains well suited for the new spatial requirements. Furthermore, the building is being expanded on the south side to accommodate new school services. Along these lines, the entrance lobby will be spatially refined and improved. The atrium will be covered and, with a generously sized staircase, is being converted into the school's central gathering point. The rainscreen cladding is undergoing a fundamental redesign as a 2-layer glass construction (CCF facade). The rhythmic interplay of the coloured glass elements gives the new secondary school building in Horw a distinctive, unique appearance.
