The building is structured around two large, central spatial elements, one containing common areas with a canteen, reception hall and knowledge centre on three storeys, and the other being a larger sports and multi-purpose hall with three arenas. A large, sloping copper roof connects these two spatial elements, with the masonry being built with yellow bricks. The school’s physical location and design take a point of departure in the site’s interaction with the town of Schleswig and Slien Fjord, as well as in the desire to create timeless architecture.

By grouping the traditional classrooms around the assembly hall and the common functions, a simple basis has been created for daily freedom of choice in the form of teaching, as well as a high degree of interdisciplinary co-operation between the various subject groups. Not only the classrooms, but also the entire school provides a teaching environment for individual work, group work and plenary sessions.

The school's interior openness and organisation provides a starting-point for modern, democratic teaching in a varied educational environment.
