The expansion and extension building of the Sonnenberg school complex in Thalwil impresses with a slender timber construction extension that harmoniously adjoins the existing structure. Technically, the project relies on prefabricated timber elements, a new external fire safety staircase, and an energy-efficient facade construction.
