Ruth is an artist who lives in the Rocky Mountains in the U.S. state of Colorado. Over the years, she found and collected a lot of old objects for her art. When she decided she wanted to live in a more unusual home, she had a creative idea. She would use many of the old materials that she collected in the home's design. For example, she used old car parts in the front door and tire rubber as the roof. She also used the door of an old car as part of a wall so she can still lower the window!
