The mixed tower (town hall shops housing) is planted with hanging gardens adapted to the coastal micro-climate characterized by a strong sea wind in the upper floors (max. 300km/h at 50 meters). The trees in the tower are anemomorphic sculptures whose species are chosen to have a flexible branching that bends but does not break during storms: Hippophae rhamnoides, Cratægus monogyna, Cupressus marcrocarpa, Tamarix gallica, Quercus ilex, Olea europaea… Participatory greenhouses allow self-consumption. On the ground, a public square on slab hosts a weekly market, shops, an active public garden and an inaccessible dune climax garden.
