Nancy neighbourhood units.The council flat blocks on the Plateau de la Haye for the Nancy OPAC (French public housing office) are economically designed.Based on a simple post and beam structure (car park frame), three living spaces organised together propose a new way of living:- the well-insulated, walk-through interior living space (the dwelling per se);- an inter-climatic space, e.g., winter garden or veranda;- a planted space for gardening or pleasure.Every dwelling features these three elements, each arranged differently depending on the size of the apartment and its orientation.All the dwellings can be accessed via a broad walkway detached from the façade and punctuated by the verandas and the kitchen gardens.The two buildings are separated by a hardy garden open to inhabitants and a mineral courtyard that gives onto all the services (entrance hall, letter boxes, bicycle park, push-chair storage…)These neighbourhood units offer a different way of living because the interior and the exterior are always directly connected, the layout of the flats is very open and adaptable to the inhabitants’ needs, and the interior living area is prolonged by an exterior living area that promotes neighbourhood relations.The energy and material savings implemented in this project are explicit.New spatial combinations for a different way of living.
