A school with fifteen classrooms, to be constructed inside a dense, old, built-up city block on a vast 11.000 m2 site. High walls hide a huge private garden two centuries old, secret and unexpected, consisting of rich and varied plant varieties -a wonderful garden, far from the noise of the city.

The wish to keep this fragile and delicate garden all of a piece as a precious public inheritance is established as the irreversible basis of the project.

The building is inserted on the very edge of the garden, so as to perpetuate its boundaries once and for all. Playgrounds occupy the rest of the terrain.

The garden will become a classroom totally integrated into the school, a "nature class" in the middle of the city, a teaching garden for looking at, cultivating, planting flowers, playing in, learning botany.
