Exquisite coastal masterpiece blends cutting-edge design with the ultimate in waterfront luxury. (2 Bed+Flex rm.) Sits at the water's edge and framed by optional dual 20-foot firewalls, the home showcases natural stone, custom steel fabrication, and expansive Nano doors that open for seamless indoor-outdoor living. The State-of-the-Art kitchen offers Italian steel cabinetry, marble countertops, and a wall that opens to outdoor bar-perfect for entertaining. Rough-cut interior stone walls add depth and texture, while mood-enhancing LED-lit soffits illuminate the home at night as shipping lanes and sunsets unfold before you. Primary suite opens fully to the expansive patio, and the spa bath stuns with floor to ceiling marble and glass closets.
