This waterfront family home fronts the placid western shore of Sag Harbor Bay on the east end of Long Island NY. Formally activated by barns the world over, it presents a rational plan of two rectangles at right angles, one to another. The longer form runs parallel to the beach and shelters the social functions of family life, while the shorter “barn” houses multiple bedrooms of various sizes with forested views to the sea. Between the two wings, a forecourt frames a welcoming view to the water. A large, south-facing screened porch and a 125-foot-long waterside terrace further connect the house to its site, its landscape, and a pre-existing, mid-century beachside cottage, all culminating in a tranquil waterfront repose.
