The Courtepin school site is characterised by a heterogeneous grouping of three autonomous built-up areas that spread out along the slope in a permeable, landscaped outdoor space.

The new building fits in with the existing layout. Its location makes the most of the existing courtyards to reinforce the central meeting place of the school circle. Improving the entrance to the site from the north-west, the different orientations of its facades accompany and direct pedestrians arriving from the new car park area, where a new canopy will house a bus stop and cycle parking.

The semi-buried building, around which the natural terrain turns, reads like a multi-oriented prism suggesting rotation in correlation with its interior plan and the rotation of its classrooms between two floors. The interior layout of the classrooms is organised radially around a common distribution centre, where the zenithally-lit staircase is located. This central core expands and contracts towards the light, offering diverse perspectives with multiple orientations.

The architectural choices made and the materials proposed correspond to a simple type of construction in keeping with the economic and sustainable nature of the project. The load-bearing structure is made of reinforced concrete. The superimposition of certain walls from the foundations to the roof ensures the stability of the structure. A system of load-bearing walls allows the classroom modules to rotate from one floor to the next. The ventilated facade ensures good durability and optimises regulation of the building's temperature and humidity.
