With its 380 000m2 surface area, "the Mart" snatched the title of the largest building in the world. The architects Graham, Anderson, Probst & White enhanced its Art Deco silhouette with sober geometrical motifs engraved and incrusted on the façade. In the main hall (south entrance), frescoes by Jules Guérin tell the story of international trade. On the ground floor, LuxeHome has almost 10 000m2 of luxury shops that are open to the general public.
