Shoichi wanted to live in an environmentally friendly home, and he always liked the greenhouses in his neighborhood in Tokyo, Japan. So he decided to create his own greenhouse-style home. Sunlight warms 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. Ruth is an artist who lives in the Rocky Moun
