The “Boucle de la biodiversité” project is presented as a functional and sustainable solution. The environmental platform is built around a high dock to the west of the plot and a low dock to the east. In order to limit the earthworks. The project has been based on the natural topography of the site.
The intensive greening of the plot allows the project to integrate harmoniously into its near and far environment. In addition, the coating of the plateform with green alveolated slabs allows permeability and zero discharge of rainwater into the earth.
