Private, polished, and distinctly North Fork, this designer's own Nantucket-style home offers generous spaces and exceptional privacy at the end of a long drive near historic Horton's Point Lighthouse. Set on nearly an acre of mature landscaping, a wide mahogany porch opens to a dramatic foyer and expansive, light-filled living area with custom moldings, French doors to patio and plantation shutters. The heart of the home is the spacious, sun-filled kitchen and breakfast room, where Carrera marble counters, an oversized island and French doors to the deck and patio create an easy flow from morning coffee to summer entertaining. The adjoining formal dining room offers a more traditional setting when the occasion calls for it. The main-level primary suite, with high ceiling, wide oak floors, large closet and renovated bath with soaking tub and Carrera-tiled shower, makes first-floor living effortless. An office/library, powder room and laundry complete the main level. Upstairs, an airy loft leads to three spacious bedrooms and a full bath, creating comfortable separation for guests. In the rear yard, an expansive exotic-wood deck with pergola, stone patio and fire-pit area overlook a fully fenced lawn and established gardens with mature hydrangeas, crepe myrtle, raised vegetable beds and evergreen screening, with room for a pool. The detached two-car garage with additional storage connects by covered portico. Close to LI Sound beaches, Southold and Greenport Villages, wineries, farm stands and local 5-star restaurants.
