The operation consists of developing the spaces free of any building into high-quality public spaces with new developments and new uses. The project for the development of public spaces in Toulouse Métropole foresees the construction of new sleeper gardens and a new park in the heart of the Poudrerie sector (development of the Poudrerie prairie). The public spaces project accompanies the projects led by Toulouse Métroôle Habitat on buildings in the sector and projects to be developed by the City of Toulouse around the school group Léo Lagrange
