The materialization in definitely simplified: huge windows ( minimum thermal leakage window profiles and glasses) and close-knit matt surfaces (high thermal performance ratio). A distinctive feature is the great hall ceiling slab (span 15 meter; cantilever 6 meter) built with post-tensioned reinforced concrete. The school belongs to city outskirts, directly facing hills. Maximum integration with the natural surroundings is thus a capital design goal. In particular the inner lobby, a sort of gallery which visually connects all rooms, recives light from outside, thus hinting at the greenery that encircles the school.
