I modified this small (under 1000 sq ft), flat roofed, Swiss retreat with a very small ecological footprint by Alberto Briccola into a Bright Idea Home. It features a Greenhouse Cap/large skylights, window wall, airlocks, and windscoop, and has 3 bedrooms and 1-1/2 baths and can sleep six if the smaller bedrooms have bunk beds. Notice the upstairs hallway length is justified by its use to provide access to the north wall of storage cupboards and closets for the bath and bedrooms. Clik on individual pictures for larger view details.
