The Dunes

High atop a wooded dune, a quarter-mile-long steel boardwalk connects a lavish garage/loft to a 6,500-square-foot modern home with three distinct living spaces. The stunning copper-and-stone exterior complements the multiple balconies, Ipe decking and outdoor entertaining areas, which feature an elaborate grill and large swim spa. In the main structure, which uses radiant floor heat, the enchanting wine grotto has a large, climate-controlled wine cellar. There is also a sauna, elevator, and private master balcony with an outdoor fireplace.
