The Maurice Genevoix secondary school in Montrouge features a large mineral courtyard, aging buildings dating from the 1990s and functional housing. The first phase of the project consists in working on the ground of the courtyard, integrating an ecological and environmental dimension by making the soil permeable and creating oasis of freshness. The creation of an educational garden promotes permaculture and integrates the notion of the environment. The work on the courtyard is the first phase of a total renovation project for the school.
