The project Core d’enfants proposes the transformation of a school pavilion from the 1960s, designed by Marc Piccard, located within the Pierre-Fleur complex in Lausanne. It questions how educational space can be structured not through separation, but through a relational centre.

The title introduces a deliberate ambiguity: Core refers to the spatial nucleus around which the project unfolds, while d’enfants does not only designate its users but also suggests a spatiality produced, inhabited, activated, and continuously reconfigured by the child themselves.

The project is organized around a central circular device, the true heart of the system, around which two symmetrical classrooms are structured. A multifunctional sliding wall allows these spaces to be connected or separated at specific moments, transforming the classroom into an evolving system. This project acts as a spatial interface where gathering, autonomy, and sharing are negotiated in rhythm with daily uses.
