This project tests the theory of bringing high quality design to a prefabricated factory setting. Enrolled in the LEED-Home Pilot, this residence completed certification. The home was conceived as two boxes that slide above one another to create outdoor living space and a lower covered rear entry. The passive solar design invites large amounts of light from the south while minimizing openings to the east and west. Factory construction saves both time and costs while reducing waste and using a controlled labor force.
