The project is an interior renovation of an existing building and seeks to establish a coherent whole operation by adapting the program to the needs and uses of new users. The intervention is essentially a reorganization of interior spaces, limiting interventions on buildings and ensuring optimization of quality and comfort of use. The general principles of circulation of the old building are maintained and adapted to the standards required by the change of destination. To provide a spatial quality and attractiveness to the central atrium, the "hanging boxes" are deposited along the passageways in R+1 and R+2. They are spaces of conviviality and collaboration between students, teachers, and administration. The staggered views offers a real centrality to what was previously a single empty. These entities are involved in both the formation of identity and its new usability.
