11 & 12 Fish Cove Road Spanning nearly 2.5 acres with 400 feet of waterfront and a private dock, this exceptional Southampton compound offers a remarkable sense of space and privacy along North Sea Harbor's tranquil Fish Cove. The five-bedroom, five-and-a-half-bath residence offers 5, 000 square feet of above-grade living space, complemented by sweeping harbor views, expansive grounds across two separate parcels, and boating access to Peconic Bay. Generously proportioned interiors embrace the waterfront setting, with expansive windows and French doors framing the views and opening to broad mahogany decks. A gracious foyer introduces a spacious kitchen, formal dining room, and inviting living and gathering spaces, while a sunroom provides a quiet retreat. A main-level guest suite complements four upstairs bedrooms, including two expansive suites with private outdoor spaces. A three-car garage completes the residence. Outside, a bluestone terrace surrounds the 20-by-40-foot heated gunite pool, framed by mature landscaping and sweeping lawns. The exceptionally expansive backyard offers ample space for outdoor entertaining and recreation, with room for a tennis court, subject to necessary approvals. The private dock brings boating, kayaking, and days on the bay into everyday reach. An unfinished 2250 SF lower level with impressive 10.5-foot ceilings presents the opportunity to create additional media, fitness, and recreation spaces, bringing the potential finished living area to approximately 7, 300 square feet across three levels. With extensive shoreline, substantial acreage, and a private dock, this distinctive offering provides an exceptional setting for Hamptons waterfront living, minutes from Southampton Village and ocean beaches.
