Steel and mesh have formed a web-like canopy around the Cs Somme Cafe in Fukuoka, Japan. Designed by architecture studio Kengo Kuma and Associates, the structure is built from a framework of interlocking steel parts, creating an earthquake-resistant structure for the single-story cafe.

The cafe is in an inner rectangular volume, connected to a network of steel beams supporting the mesh canopy, a modern version of a flying buttress.

The interlocking of the arched steel frame supporting the mesh and the grid-like steel frame supporting the inner rectangular boxes ensures sufficient earthquake resistance in spite of the thin members.

The web-like canopy helps to reduce the cafe’s energy demand by limiting solar gain. However, where it meets the ground, a series of arches provide outward views for visitors.

White walls, concrete flooring, and steel elements serve as a backdrop, set off by wooden seating alongside the bar.
