About this property
An Oceanfront Masterpiece with Infinite Horizons Commanding a premier position above the crystal-clear waters of the Atlantic, this exceptional open-water estate represents the pinnacle of refined island living. With its highly sought-after southern exposure, 258 W Seaview Circle is immersed in golden sunlight throughout the day, offering uninterrupted panoramic ocean views and the gentle cadence of waves just steps from the residence. Beyond the protective breakwater, a pristine sandy shoreline and natural sandbar unfold-an idyllic extension of your private coastal sanctuary. Designed to seamlessly balance sophisticated entertaining with effortless relaxation, the estate features an impressive 112-foot bi-level dock and seawall, perfectly suited for the discerning boating enthusiast. The oceanfront terrace is anchored by a striking 50-foot lap pool, elevated eight feet above sea level to maximize views and serenity. Framed by a charming Tiki hut, lush tropical landscaping, and curated ambient lighting, the outdoor living spaces transform into an enchanting seaside retreat as evening falls. Inside, classic craftsmanship is paired with modern elegance. This four-bedroom, three-and-a-half-bath residence offers a coral rock fireplace, private elevator, and a generously proportioned gourmet chef's kitchen designed for both everyday indulgence and elevated culinary experiences. Every detail-from the architectural finishes to the meticulously maintained grounds-reflects exceptional care, quality, and pride of ownership. Whether hosting intimate gatherings beneath the stars, savoring tranquil mornings overlooking endless blue horizons, or setting out for a day on the water, 258 W Seaview Circle delivers an unrivaled lifestyle in Duck Key, widely regarded as the Middle Keys' most prestigious enclave. Residents enjoy access to two marinas, watersports, and local dining within this charming, golf cart-friendly island community.
