Dome House by Japan Dome House Co.Ltd
Dome House is another great example of creative Residential project by home manufacturer Japan Dome House Co.Ltd. Dubbed the “habitat for the 21st century,” 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. Dome House kits start at around $30,000 which excludes the cost of delivery, assembly and interior construction, etc.
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.
Dome Houses, which are approved by Japan’s Land and Transport Ministry, can be erected anywhere in Japan with the proper permit. According to the manufacturer, the versatile structures are suitable for use as hotel rooms, restaurants, freezer rooms, or even as hog farms.
The Aso Farm Land resort village in Kyushu uses about 480 styrofoam domes as lodging, recreational facilities and retail shops.
