A 1,200 square foot vacation house fits into a natural break in the topography to become a threshold between the public and private sides of the property. The north side of the house is closed, except for a well-concealed entrance, while the south opens to views of the meadow and deck. The metal siding matches the ashen color of tree trunks and the stone-walls that surround the property. The house hides in the woods and fits into the earth. However, accentuated surfaces and highlights are intended to catch the eye. Passive solar strategies, panelized construction, a super-insulated envelope, and radiant heating all make the house energy-efficient.
