These mushroom shape houses by Japan Dome House company. Its unique shape and material(polystyrene) that enable energy savings(green) and many benefits. The Dome House is an igloo-shaped structure built from snap-together wall sections made of 100% expanded polystyrene foam. Use the styrofoam?! Unlike wood and metal structures, it is also highly resistant to earthquakes and typhoons and the walls with the flame retardant features it will no toxic fumes in a fire. The best part is can be built in quick and easy. The prefabricated pieces, which each weigh about 80 kilograms (175 lbs), can be carried by 2 or 3 people and assembled in a few hours. Once the shell is put together, coats of mortar and paint are applied for further protection from the elements(watch the video, check out more). Interior of house's pics, see here.
