Located on a steeply sloping lot in the hills of Montauk, Long Island overlooking Fort Harbor Pond and a nature preserve, this new 5,000-square-foot beach house was carefully situated to take advantage of the spectacular views, to blend in with rolling landscape, and to preserve the site’s 100-year-old oak trees, one of which now provides a focal point for the glassed-in breakfast room. We designed the house in the classic American Shingle Style that was popular at the seaside in the Northeast during the late 19th century. An L-shaped covered porch wraps two sides of the shingled house, its ceiling formed of classic tongue-and-groove cedar planking, stained a warm brown. Handmade copper lanterns complete the picture of simple, crafted detailing that characterizes the style. The open and airy interior has a combined kitchen/family room opening onto a bluestone terrace with an outdoor fireplace, a formal dining room, a formal living room with fireplace and window seat, a wine cellar, a dressing room and a classic pantry. Because French doors connect every public room to the porch or terrace, all enjoy expansive views. Photos: Emily Gilbert
