A series of identical rectangles linked up by walkways, as if cut up into slices of cake: this is the national Chamber of Commerce. The steel and glass building was designed by French architect Claude Vasconi (2004), assisted by Luxemburger Jean Petit. Inside is no less than 35 000m2 of office space. Despite its gigantic scale, the building has a pared-down style. Take a tour of the premises to better appreciate the vigour and clarity of the architecture.
