An Oceanfront Masterpiece with Endless ViewsPoised above the turquoise waters of the Atlantic, this extraordinary open-water estate epitomizes the essence of luxury island living. With a coveted southern exposure and sweeping, unobstructed ocean vistas, 258 W Seaview Circle bathes in golden sunlight from dawn to dusk, accompanied by the soothing rhythm of the sea just beyond your doorstep. Beyond the protected breakwater lies a pristine sandy shoreline and inviting sandbar, creating your own slice of tropical paradise. Designed for both effortless entertaining and relaxed coastal living, the property boasts a 112-foot bilevel dock and seawall--a dream setting for boating enthusiasts. A 50-foot lap pool stretches gracefully along the oceanfront terrace, elevated an impressive eight feet above sea level. Surrounded by a Tiki hut, lush tropical landscaping, and soft ambient lighting, the expansive outdoor spaces transform into a private seaside retreat after sunset. Inside, timeless craftsmanship meets contemporary sophistication. This four-bedroom, three-and-a-half-bath residence features a coral rock fireplace, elevator, and a spacious gourmet chef's kitchen equipped for culinary excellence. Every element--from the refined architectural details to the impeccably maintained grounds--reflects pride of ownership and a commitment to uncompromising quality. Whether you're hosting friends beneath a canopy of stars, enjoying a peaceful morning overlooking endless blue horizons, or embarking on a day on the water, 258 W Seaview Circle offers a front-row seat to the serene beauty of Duck Key, the Middle Keys' most prestigious address.
