The school centre and the bus shelter are placed in the middle of a new ensemble of residential buildings. The project underlines the special nature of these public facilities. The four buildings are set apart from one another by virtue of a series of geometrical rotations creating intervening spaces that open into one another. Each of these four "objects" deposited upon their plateau of brushed concrete is enveloped by a double glass skin which ensures rational management of heat exchange. At night, this double skin lights up according to the result of the accumulated energy. Like four fireflies, their fluorescence epitomises the playful character of this public space.
