Schulhaus Waid Pfäffikon

The Waid school site in Pfaeffikon lives from its gentle, undulating topography. The surroundings east of the Rustel Stream consist of heavily scattered single- and multi-family houses, complemented by larger public, commercial, and agricultural buildings that form sub-centers and structure the townscape. The new upper-level school Waid for up to 600 students orients itself in its extension to these sub-centers, fulfills the claim to publicness, and remains in harmony with the site and its surroundings through the articulated volume and the stepped height development. The compact, predominantly two-story school with basic dimensions of 88.80 x 57.40 m placed in the lower half of the perimeter in the first construction phase. It acts as an ordering element and uses the site up to its natural boundaries. On the amorphous terrain, outdoor spaces of different publicity emerge intimate green areas towards the forest and playground alternate with public, communicative areas in the south. The second phase expands the school by 15 classrooms and completes the schoolyard, meeting the requirements of a large school facility.

The building consists of layered interior and exterior spaces. The horizontal articulation of the flat ceilings supported by the main circulations running north-south. Courtyards function as connectors, not dividers, and trace the natural slope of the terrain. Although the school is mainly organized on two levels, it appears three-story due to the cross-slope to the valley. Public areas promote movement and communication, while the cultural courtyards provide places of calm and concentration for different teaching and learning forms. Group rooms at the end of the classroom wings extend the corridor and connect the interior with the covered exterior space. The main access is on the south side, where the wing with auditorium and gymnasium accessed independently of the school operation.

The classrooms are based on a grid of 1.30 x 1.30 m and are modular in construction. Floor-to-ceiling east-west window fronts in pilaster-like timber frame constructions ensure glare-free daylight. Textile elements provide shading and darkening, while massive flat ceilings improve acoustics. Acoustic measures are limited to ceilings and rear walls; in the teachers’ area, reflections deliberately retained.

The materialization relies on raw, untreated surfaces, matching the primary building elements. Poured asphalt surfaces refined with local granite granulate and inlays, walls consist of Baecher sandstone. Wooden facades remain raw; larch is matt impregnated. A compact volume, fixed glazing with ventilation flaps, buffer zones, and mechanical ventilation allow for low energy consumption and comfortable room temperatures. Roof surfaces offer potential for solar energy or rainwater use.
