A former one-room schoolhouse, this home was renovated by a green-building-supply store owner, who used earth-friendly materials such as bamboo flooring, low volatile-organic-compound paints and natural earth-plaster wall finishes.

Pros: A 400-square-foot converted garage, heated by high-efficiency soapstone wood stove, could be a studio or an office.
