the Dome House is an igloo-shaped structure built from snap-together wall sections made of 100% expanded polystyrene foam (styrofoam). It might seem like an odd choice of material for a house, but the company lists a number of advantages that styrofoam has over traditional materials. Unlike wood and metal structures, for example, the styrofoam Dome House does not rust, rot or attract termites. It is also highly resistant to earthquakes and typhoons. In addition, the walls, which are treated with a flame retardant, emit no toxic fumes in a fire.
Measuring 7.7 meters (25 ft) wide and 3.85 meters (13 ft) tall, the basic Dome House has a floor space of 44.2 square meters (475 sq ft). It is possible to construct larger, elongated domes by adding more pieces, and joint units allow multiple domes to be connected into a single structure.
