11 social housing units in Paris by Chartier-Corbasson
Winner of the Prix Grand Public for this social housing scheme, the practice Chartier-Corbasson offers an original refurbishment of a seventeenth-century Parisian building. Located on rue Saint-Antoine in the 4th arrondissement, the building's gable wall ran along three quarters of the length of the plot. It was this particular feature that prompted the decision to bring the gable back to life.
The architects chose to retain the building, keeping the traces left by the demolition of its neighbour for the creation of rue Turenne.
A new volume has been grafted onto it to give the gable a façade and to gain light and floor area. A skin covers this new element, giving the project a unified appearance within the permitted envelope.
The new volume is a substantial one and plays a dual role: it unifies the building, creating balconies and a circulation space, and it provides a new zone of privacy. The panels are bronze-toned anodised aluminium sheet, and some of them slide, allowing residents to shield themselves from the sun and from prying eyes. It is also a way of creating a view for the residents, since most of the rooms face this street.
Originally, the building faced a poorly lit courtyard, and the architects took the opportunity to reposition the vertical circulation (lift and stairs) so that it opens onto the access galleries. Each dwelling has a terrace or a balcony, and the adjoining flat roofs and the party gable wall are planted with greenery, the species chosen for their hardiness and low maintenance.
The façade, made up of double glazing fixed to a frame, optimises the building's acoustic performance. Air intakes in the façade are provided by silencers fixed into the walls rather than into the window frames.
To limit energy consumption and the associated emissions, gas has been chosen as the energy source.
The wet rooms are stacked from one floor to the next, which simplifies the service networks and reduces noise between neighbours. Water consumption will be reduced by appropriate measures, and rainwater will be collected to water the planted terraces.
