Along one axis, the shells are kept thin with steel members as the base structure. On another axis, clear glass panels are used for the front and rear enclosures. These shells are the structure, as well as the walls, floors, ceilings, roofs, and windows of the house. This configuration generates a constantly light-filled space. The glass panels can be opened on both ends for cross-ventilations, whilst gaps between fixed glass panels serve as air-vents.
