Big in function but small in footage, this two-story passive solar design puts every inch of space to valuable and efficient use. The house can be constructed as a free-standing unit or as part of a condominium development.
The plan flows visually from its entry, through its high-ceilinged great room, to a brilliant south-facing sun room where solar heat is collected and stored in the ceramic tiled floor.
Thick insulation of exterior walls and ceilings minimize heat loss during the cold season. In summer, air flow is created by convection while eave overhangs protect against over-exposure.
