Swan's Cove - Where The Bay becomes your BackYard. Some homes have a view. Swan's Cove has a horizon. Set on Lloyd Neck's storied Gold Coast, this 10,500-square-foot waterfront estate was designed so that every room - across three sweeping levels - turns toward the water, capturing Long Island Sound and Oyster Bay in a panorama that shifts from silver morning mist to gold-lit sails to a full western sunset, night after night. Tucked at the end of a private road in the Cold Spring Harbor School District, Swan's Cove offers the rare kind of privacy that lets a family exhale, while placing them minutes from one of Long Island's most sought-after school systems. Inside, the architecture matches the setting's drama: soaring ceilings, sun-washed formal living spaces, and a chef's kitchen outfitted with Sub-Zero, Wolf, and Miele for anyone who takes cooking seriously. A commanding primary suite, four additional en-suite bedrooms, and a fully separated guest wing give every member of the household, and every guest, their own retreat. And then there's the part of the house built purely for living well: an indoor spa complex with pool, sauna, and gym, a private tearoom, and a home theater built for a proper premiere night. Step outside to more than 2,200 square feet of multi-level decking, the best seat on the Sound for sunset, sailboats, and salt air. Beyond the property line, life at Swan's Cove comes with membership in a rare kind of community: Lloyd Harbor's private beach and park, with tennis, summer camp, a boat ramp, and mooring rights all within reach. This isn't just a listing. It's the chance to own one of the Gold Coast's defining waterfront addresses, a legacy property, ready for its next chapter.
