This little house has a 12 foot by 24 foot footprint [the space taken by a small one car garage]; these dimensions were chosen because they are comfortable on many residential lots. Economies in the design are created by managed constraints such as: footprint, interior partitions, doors, and materials. The house is designed on a four foot module to be constructed with modular SIPS panels or stick framed. There are only three doors in the house, including the shower door. Dwellers have flexibility of arrangement by using furniture rather than fixed closet locations. Floor to floor heights are eight feet in the kitchen and bath, twelve feet in the living and bedroom areas. The effect is open and loft-like. Building components include: concrete foundation, basement, insulated walls, insulated and reflective roof, Ipe wood roof deck tiles, insulated low-E windows, and energy-star appliances. The exterior is wrapped with blueskin® building wrap and clad with a ventilated cedar lap siding rain screen and cedar shakes.
Heating: Evacuated-tube solar thermal panels on the roof linked to a 100 gallon storage tank, radiant tubing in all floors, and a high efficiency boiler provide for heating and domestic hot water needs.
Cooling: The vertical living space in Wellfleet’s climate supports natural cooling during the summer months. Breezes captured via low windows are drawn through the house and exhaust heat and humidity through high windows. A zoned, ductless split system provides supplemental air conditioning for muggy summer days.
Adaptability: The house may also be constructed in duplex arrangements. It may be elevated on piers for minimal grading. Segments may be added to the base dwelling to expand for additional bedrooms, home office space, or more living area. The module may also increased to 16 feet by 24 feet.
