Between city and nature, between work and habitat, this mixed project functions as a city on its own. A skyline – composed of volumes with varied heights – animates the visual sequence of a new pedestrian street. Following the principles of the « global city » and the « city of tomorrow », both housing and SME spaces are designed as to o er maximum exibility and adaptability. Beyond the intrinsic qualities behind the integration of collective spaces, the project proposes dIfferent building typologies - a tower and two pairs of urban blocks – with an architecture and functioning going far beyond the traditional juxtaposition of functions. A constellation of collective spaces, backbone of the project, fosters encounter, exchange and conviviality.
