Open air school

The square classroom block spans four levels with a diagonal central staircase, featuring large windows and concrete columns placed along the quadrant sides.

Architect Jan Duiker received a commission in 1927 to design this structure, which opened in 1932 to support children through exposure to sunlight.

The building represents the Nieuwe Zakelijkheid architectural movement, emphasizing structural clarity through its geometric forms and transparent surfaces.

The structure contains multiple classrooms per floor, a sunken gymnasium beneath the main block, and a staffroom positioned in the north quadrant.

Floor slabs extend over the main beams with cantilevered supports, creating a distinctive floating effect while maintaining structural balance through diagonal coupling.
