Oberstufenschulhaus, Secondary school building in Paspels, Switzerland.

The Oberstufenschulhaus in Paspels is a school building of exposed concrete with clear cubic forms, completed in 1998 to plans by Valerio Olgiati at Stradas 4. Its cross-shaped circulation system brings daylight from all directions. Deep reveals conceal a wooden classroom, while flush-mounted windows front the concrete stairwell and break halls.

The building was constructed in 1998 following a design competition, with architect Valerio Olgiati bringing an innovative concept to life. This project emerged from the need to expand local school capacity and provide contemporary learning spaces.

The building's name is tied to its role as Paspels's Oberstufenschulhaus, the upper-level school for the village. Its 1998 opening was marked by the Hasen in Bronze award, and in 2019 the Bündner Heimatschutz included it among the «52 beste Bauten – Baukultur Graubünden 1950–2000». Visitors can spot the deep window reveals that hide a wooden classroom behind the concrete facade.

The building has large windows and clear spatial layout that make it easy to understand its design from outside. Visitors should note that this is an active school facility, so visiting outside school hours is recommended.

The cross-shaped circulation system lets daylight enter from all four directions. Deep reveals hide a wooden classroom, while the flush-mounted windows conceal the concrete stairwell and break halls. Photographer Heinrich Helfenstein documented the building, and in 2019 the Bündner Heimatschutz named it one of the best Graubünden buildings of 1950–2000.
