    What's special

    Welcome to one of the North Fork's most iconic and impeccably restored estates, where timeless grandeur blends seamlessly with refined modern living. Originally built circa 1915, this Georgian estate, formally known as the Cosden Estate, has been lovingly restored for today's modern luxuries while maintaining its historic vibe. Set on a professionally landscaped acre in one of Southold's most desirable locations, this 6,000sq ft home features 6 spacious bedrooms and 6 luxurious bathrooms. An entertainer's dream, this home includes a heated saltwater gunite pool with integrated spa, surrounded by a bluestone patio and enclosed by a classic Walpole fence with custom automated gate entry. Across the street, enjoy peace of mind and enduring views with 22 acres of unbuildable land. From the mature, symmetrical sugar maples at the front entrance to the elegant pleached elm at the rear, every inch of landscaping has been thoughtfully curated. Inside, soaring vaulted ceilings, herringbone wood floors, and a grand wood-burning fireplace define the stunning living room. Natural light pours in throughout the home, enhancing its warm, inviting atmosphere. The chef's kitchen, renovated in 2020 and refreshed in 2024, features new quartz countertops, a refinished oversized island, and custom open shelving. The primary suite offers a serene retreat with a spacious sitting room and a fully renovated spa-like bathroom with a soaking tub and a large enclosed shower. Additional highlights include, new HVAC system, upgraded ADT security system, State-of-the-art irrigation throughout, a large temperature-controlled wine cellar, and close proximity to Town Beach and Lighthouse Road Beach. The backyard is a private, quiet and peaceful oasis, perfect for relaxing or entertaining. This extraordinary estate offers a rare opportunity to own a piece of North Fork history, updated for today's lifestyle.
