For their first tiny house, Green Valley Natural Builders in Sebastopol, CA decided to build something very small, but beautiful, using only natural, unprocessed and re-used materials. What they came up with is a delightful tiny structure on wheels that cost only $1,500 to build. Because the small company is used to creating houses out of straw bales, cob and wood, they didn’t want the materials for their first 6 foot by 10 foot house to come from the lumber yard.” -Christina
