This showroom for a supplier of building materials is housed in a volume curving across the full breadth of the site. Its ground floor contains storerooms and parking spaces, with showrooms, offices and a restaurant on the upper level. The cladding alternates translucent polycarbonate panels with steel frame profiles. Informal circulation routes thread through the rooms between a number of internal patios. All piping, ducting and cables are tucked away in the floors and in the steel columns. The even quality of the light and the smooth detailing of floors and ceilings add up to an agreeably tranquil ambience in the interior.
