Beach houses come in many forms… a cozy Sag Harbor cottage from the 1700s that called for soapstone counters and open shelving… a new sprawling West Hampton house on the water with a kitchen that nods to the beach houses of the 1920s… a cape cod beachfront home that features Picassos, a Roman bust and even Oscar de la Renta fabrics….and a forlorn pool house reborn as a cozy, oak paneled getaway.
