A Rare Waterfront Offering! Tucked away on 1.39 private acres along Senix Creek with direct access to Moriches Bay, this exceptional Center Moriches waterfront estate offers the ultimate blend of luxury, privacy, and coastal living. Boasting over 100 feet of bulkhead access and room for larger vessels, this rare property is a dream for boating enthusiasts alike. The beautifully updated main residence offers approximately 3,400 sq ft of sun-drenched living space featuring 4 bedrooms and 3 baths with an open, airy layout designed for effortless entertaining. The renovated eat-in kitchen showcases quartz countertops, stainless steel appliances, a large center island, and seamless flow into the spacious living areas. A large wood-burning stove with a water view adds warmth and charm, while the first-floor ensuite provides flexibility for family or guests. Upstairs, the luxurious primary suite features a private balcony overlooking the serene water views, an incredible walk-in closet, and private terrace overlooking the water. Adding to the property's incredible versatility is a charming detached 1-bedroom guest cottage with vaulted ceilings, updated kitchen, and gas fireplace, perfect for visitors, extended stays, or private workspace. A separate approximately 1,000 sq ft workshop offers 200-amp electric, gas heat, and brand-new cesspool, ideal for hobbyists, contractors, or additional storage. A detached garage with dedicated tackle room further enhances this one-of-a-kind waterfront estate. The property includes a bulkhead with full utility service (electric and water), and with a documented jurisdictional boundary designation on file with the New York State Department of Environmental Conservation. The bulkhead establishes the line where tidal wetlands regulations apply, so the land up to the bulkhead is treated as usable/buildable upland and outside DEC jurisdiction, and a DEC Jurisdictional Determination is on file. Privately set at the end of a long drive, yet just minutes to shopping, dining, beaches, and Moriches Bay Yacht Club, this extraordinary property offers unmatched flexibility, beauty, and lifestyle.
