Sanaa in Toledo USA

The Toledo Museum of Art glass pavilion showcases glass artworks and glass-making studios. Architects Kazuyo Sejima and Ryue Nishizawa of the Tokyo-based architecture firm SANAA chose to design the building primarily out of glass. Except for opaque walls enclosing toilets, plumbing, roof drains, elevators, and diagonal bracing, all exterior and interior walls are made of curved glass.
