As an extension to the existing primary school Les Colibiris in La Hulpe, Belgium, each student had to design one of three extensions : extra classrooms, an events hall or a gymnasium.

The gymnasium, here, was designed using half of the available area of the site and connecting to an existing courtyard via a pedestrian crossing.

The roof of the building is accessible via a ramp at the back of the building and is set up as a mini-track and an outdoor yoga area.

The gymnasium is modelled on a basket-ball court. Underground, boy's and girl's changing rooms, bathrooms and an office, allow access to the court. At ground level, one can access a reception hall and the bleachers.
