The Cusset source substation, an essential facility for supplying electricity to the north-eastern area of Lyon, is located in an industrial landscape whose quality lies in the strict expression of technical requirements. Echoing the neighbouring hydroelectric power plant, the building adopts an unexpected monumentality for a programme dedicated to power distribution. Exposed concrete, rammed earth and galvanised steel form a contextual palette. A triple-height circulation space structures movements and brings natural light down to the basement.
