Inspired by the great Edwardian country homes of Edwin Lutyens, this 10,000 square-foot mansion sprawls across its hilltop site in western New Jersey. Honed white marble keystones and cornice contrast with rough face ochre stone walls and blue slate roof. Inside a cantilevered marble staircase with French wrought iron railing floats above a radial patterned black and white marble checkerboard floor. An elaborate coved and coffered ceiling crowns a 14-foot high living room.
