This thin-shell concrete roof consists of eight hyperbolic paraboloid inverted umbrellas. Each of the umbrellas consists of four hyperbolic paraboloid panels, joined at the edges and mounted on a central column. This was a prototype building for the Mr. Steak restaurant chain, but apparently it was the only one they built using thin-shell concrete.
