65 Watchogue Avenue Tucked away on a quiet dead-end street with Moriches Bay access at the end, this builder's own custom home offers more than 3, 400+/- square feet of thoughtfully designed living space in a peaceful coastal setting where privacy and convenience come together. Originally built in 1915 and fully renovated in 2006, the home honors its architectural roots while incorporating updated finishes that support comfortable, everyday living. The result is a warm and inviting space with timeless character and modern function. The main level features a formal foyer, a dedicated office with built-in shelving and storage, and an oversized living room anchored by a custom entertainment unit and wood-burning fireplace. The adjacent formal dining room is filled with natural light and features French doors that open to a covered outdoor lanai, creating an easy flow for entertaining or relaxed evenings at home. The chef's kitchen offers generous island seating, Bosch appliances, and an electric fireplace that adds both charm and ambiance. Also on the first floor: a mudroom with laundry and powder room, an en-suite den perfect for guests, a gym space, and hardwood flooring throughout. Upstairs, the primary suite provides a comfortable retreat with a large outfitted closet, soaking tub, tray ceilings, and a private balcony overlooking the property's elevated grounds. Three additional bedrooms share a well-appointed full bath with an attached washroom for added functionality and ease. Designed for year-round enjoyment, the backyard offers a seamless extension of the home with a covered lanai just off the kitchen and dining area, a detached two-car garage, a 20x40 in-ground pool tastefully surrounded by a large blue stone patio, outdoor shower and dressing room, and professionally landscaped grounds with lighting that enhances the setting day and night. With buy-in rights to nearby Hamptons beaches, no flood zone designation yet convenient bay access just moments away, this property presents a rare opportunity to enjoy refined coastal living in a truly private location.
