Shoichi wanted to live in an environmentally friendly home,and he always lived the greenhouse in his neighborhood in Tokyo,Japan.So he decided to create his own greenhouse-style home. Sunlight warms his new home,and a plastic cover around the house helps to keep the heat inside. There aren't any walls or rooms. The "rooms " are actually large boxes on wheels.He can move them anywhere he likes,even outside.He loves his home,but sometimes he would like to be able to move the whole house.
