Welcome to Swan’s Cove, a masterpiece of waterfront luxury perched along Lloyd Harbor’s Gold Coast on in Lloyd Neck. This estate spans a magnificent 10,500 square feet across three levels of breathtaking living space, meticulously designed to capture panoramic views of the Long Island Sound and Oyster Bay from every angle. Tucked away on a tranquil private road within the Cold Spring Harbor School District #2, the property offers a cinematic perspective where sunrise mists, sailboats at golden hour, and sweeping western sunsets become part of your daily rhythm. The residence itself is a statement of sophistication and comfort, featuring dramatic high ceilings and grand formal living spaces bathed in natural light. At the heart of the home, a chef’s kitchen equipped with Sub-Zero, Wolf, and Miele appliances awaits the culinary enthusiast. The accommodations are equally impressive, boasting a divine master wing, four additional en-suite bedrooms, and a separate guest wing for absolute privacy. For those seeking a sanctuary of wellness and entertainment, the estate includes a fully enclosed indoor spa, pool, sauna, gym, tearoom, and a private movie theater. Transitioning outdoors, over 2,200 square feet of multi-level decks provide the ultimate vantage point for the salt air and coastal vistas. Residents also enjoy the premier amenities of the Lloyd Harbor beach and park, which offers tennis, summer camp, a boat ramp, and mooring (fee). This estate is more than a home—it is a timeless sanctuary and a rare opportunity to craft your own legacy in one of Long Island’s most coveted enclaves.
