« This « show » building, to act as housing for the director of the college in Niamey, was intended to make up the minds of the Nigerian authorities. A vast ventilated 26 x 10 m. roof shelters two units ( for day time and night use), which are separated by a patio and surrounded by a well ventilated patio. The main structural components, such as the portal frames and the girders are in folded and welded steel sheet, all the other components ( roofing, facades, ceilings…) are aluminium. The façade components are of four types: solid panels, window panels, panels with portholes and door panels. These panels consist of two shells in 10/10 aluminium sheet, separated by insulation studs; the frames are extruded sections, insulation is by means of light-weight crumpled aluminium sheet louvers are angle-adjustable.”
