Description
An Oceanfront Masterpiece with Endless Views
Poised 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. Residents on the island enjoy access to two marinas, watersports, and local dining, all within this golf cart-friendly island community. Optional Club Duck Key membership provides exclusive access to social events, wellness programs, and sports amenities—enhancing the resort-style experience that defines life on Duck Key.
