Villa Sa Contissa (58)

Villa sa Contissa is a sleek, eco-friendly retreat in Porto Cervo, Sardinia. The home is built into a cliffside above the sea; its stone walls are evocative of the granite boulders surrounding the home; its green roof blends into the enveloping Mediterranean shrubland. The fluid, light-filled interiors, which include nine bedrooms and 10 bathrooms, reception rooms, a theater, gym and spa, open to a dazzling, 130-foot-long swimming pool. Beyond are lounging areas and lush gardens overlooking the Emerald Coast.
