Belgo Zuid.

With kitchens tucked economically away in a retained structure, diners feast on their meals in a space where the apparently conventional plywood-clad walls warp and separate into a series of asymmetrical curves for the roof, letting some daylight in and loosely resembling a plate of mussels. To keep the structure for this extraordinary shape within budget we welded additions onto basic symmetrical arches; between them the roof is a simple joist, plywood and standing seam construction. Resolving all the structural complexities into the new arches also meant that the only new foundations needed were under them.
