Redevelopment of the former Émile Loubet high-rise building in Saint-Étienne
The project consists in transforming a high-rise building that is emblematic of 1970s administrative architecture into an urban facility with a dense, mixed-use programme (cinematheque, municipal archives, memorial centre, municipal police headquarters, housing and offices). It is based on two principles: revealing the intrinsic qualities and potential of the existing structure through selective stripping-out and restoration; repairing the relationship to ground and sky by means of targeted, clearly legible interventions: subtracting a corner of the base on the north side and creating a square to the south to improve the connection with public space, adding a rooftop volume and a new escape staircase.
