Millfarm Lane on Reserve Perfectly positioned on Millfarm Lane, one of Water Mill's most desired and consistently appreciating locations, this classic Hamptons traditional home captures the absolute best of Hamptons living. Positioned on a pristine 0.73-acre lot, abutting a 20+ acre forever-protected agricultural reserve. The home's layout is perfectly aligned with a highly coveted southeastern backyard exposure, bathing the primary living spaces in brilliant natural light and guaranteeing maximum, unobstructed sun across the pool during peak summer months. Ready for immediate luxury living today and for generations to come, the home offers 6,530 +/- SF of total living space (including the unfinished lower level with egress that awaits your imagination), 4 bedrooms, 5.5 baths, a fireplace, an attached 2-car garage, and a heated saltwater gunite pool. Thoughtfully expanded and renovated since 2019, the turnkey home is highlighted by 9' ceilings, high-end moldings, and easy indoor-outdoor living and entertaining spaces. Pocket doors connect the spacious living room, which is equally suited as a study, to an inviting gathering room with a wood-burning fireplace and glass doors opening onto the stunning grounds. At the heart of the home, the eat-in kitchen includes a breakfast area, a central island with seating for 4, granite and quartz countertops, and a 5-burner Thermador gas cooktop. The adjoining dining room and outdoor patio offer easy options for dining indoors or out. On the main level, a wing for everyday living can be accessed from the interior and the side entrance, leading to an oversized mudroom with a pantry and nearby storage closets. The well-appointed laundry room offers stone counters, cabinetry, a barn sink, and a desk alcove, while a powder room is directly accessible from the patio. A convenient first-floor junior primary suite includes a walk-in closet and a bath with radiant-heated floors, a shower, and a double vanity. A dedicated staircase leads to a bright media and billiards room with a wet bar, wine and beverage fridge, and full bath. An adjoining attic provides additional storage, and an oversized 2-car garage accommodates fitness, storage, and parking. Upstairs, the primary suite enjoys views across the agricultural reserve and a sunlit bath with a double vanity, shower, and freestanding tub. Two spacious guest bedrooms complete the floor, each with a private bath, one ensuite. Outside, tall privet hedges frame the fully manicured grounds, accented with specimen plantings and landscape lighting. Adding to the classic Hamptons feeling, two expansive bluestone patios connect the home to a heated 20'x40' gunite saltwater pool, and a broad lawn provides room for outdoor gatherings, complemented by a storage shed and a productive vegetable garden. Just 1 mile from the Hampton Jitney, 1.5 miles from Water Mill Square, and 2 miles from Southampton Village, the home puts ocean beaches, boutiques, and fine dining within easy reach in one of the East End's strongest-performing real estate corridors.
