ANCHORED ON NEW ENGLAND'S rocky coastline and oriented to maximize coastal vistas, this 10,000-square-foot retreat reads like a polished outgrowth of the terrain. A simple palette of wood, mineral, and steel carries fluidly from indoors to outdoors and befits the region's rough-hewn beauty. Stone quarried from the site lends texture to the base massing, interior walls, and muscular fireplace surrounds. On the porch, pencil-thin cable railing provides unobstructed views of the water. It's like sitting on the deck of a ship.
