About this home

Bay Haven — 1430 Bay Haven Lane, Southold Classic coastal architecture meets contemporary North Fork living in this newly built custom residence set within the Bay Haven beach community, just three houses from the private community beach. Designed for effortless North Fork living, the home offers 3,035 square feet of living space, with four bedrooms and four full baths, complemented by approximately 3,340 additional square feet of garage, pool house, storage/art, and under-house utility and storage space. Inside, 10 foot first-floor ceilings, 9 foot second floor ceilings, natural hardwood floors, abundant natural light, custom millwork, built-ins, and site-built closets create a refined yet relaxed interior. Two primary suites, one on each floor, offer flexibility for year-round living and guests. Each features a walk-in closet, ensuite bath, and electric fireplace, while radiant-heated floors enhance the primary bath spaces. The first floor suite also includes a private office, while the second-floor suite enjoys seasonal bay views. At the heart of the home is a locally handcrafted kitchen with cabinetry extending to the 10 foot ceiling, a 48-inch professional style gas range beneath a custom arched hood, dual dishwashers, smart combination wall oven, farmhouse sink, pot filler, dual-zone wine refrigeration, and extensive custom storage. Indoor and outdoor living flow naturally through the three-season room, complete with custom cabinetry, TV hook up and fireplace, to the landscaped grounds and a heated pool. A poolside mudroom provides direct access to a full bath, shower, and changing area. The pool house adds another layer of entertaining space with a wine bar, dual zone wine refrigeration, and glass doors opening directly to the pool. The property extends well beyond the main residence with a detached garage and approximately 770 square foot second floor storage, ideally suited for an Art Space, plus approximately 1,800 square feet of under-house storage and utility space. Behind the design is a substantial infrastructure package: a high-efficiency five zone heat pump heating and cooling system, 3 zones of radiant heat, comprehensive spray foam insulation, a hybrid heat-pump water heater, three stage whole house filtration, controlled under-house dehumidification, energy efficient heat pump pool heating, smart pool control and lighting systems, Ring security, an I/A septic system, and 300-amp electrical service. Bay Haven combines privacy, craftsmanship and modern comforts with immediate access to the Bay. Cedar Beach is just 1.5 miles away, with the shops and restaurants of Southold nearby. Seasonal second floor bay views and year round glimpses of the water complete a home equally suited to summer escapes and year-round North Fork living.
