South of the Highway · 1.9 Acres · 5,000± Sq Ft · 5 Bedrooms · 6.5 Baths Tucked within the prestigious Estate Section of Southampton Village, south of the highway and set on 1.9 private acres with 120± feet of waterfront along Taylor Creek, 344 Great Plains Road unfolds like a modern Hamptons classic-quietly grand, elegantly remodeled, and perfectly composed for luxurious indoor-outdoor living. From the moment you enter the sweeping private driveway and step through the front door, the home tells a story of timeless architecture married with a complete top-to-bottom renovation that honors both sophistication and ease. The double-height entry hall sets the tone, flooded with natural light that pours in from every direction thanks to a thoughtfully opened and cleared landscape. Sightlines extend through the great room's towering ceilings and over a dozen French doors that lead to stone patios, expansive lawns, and serene water views. Throughout this 5,000± square-foot residence, matte-finished hardwood floors, custom millwork, and refined lighting create a warm, modern elegance that feels both curated and inviting. At the heart of the home, the brand-new chef's kitchen blends clean design with professional-grade functionality. Marble countertops sweep across crisp custom cabinetry, framing a full suite of premium appliances, including a Wolf range, dual dishwashers, convection and microwave ovens, a Sub-Zero refrigerator/freezer, and under-counter beverage coolers. A breakfast area surrounded by glass opens to the gardens, completing a space tailor-made for gatherings both casual and elevated. The home's layout is thoughtfully considered, offering both a sense of flow and privacy. A guest suite on the first floor, situated adjacent to the den/family room, is ideal for company or multigenerational living. A convertible office with its own full bath in the kitchen wing provides flexible space for work, play, or additional sleeping arrangements. Up the gracious staircase, the primary suite becomes a private retreat-featuring its own fireplace, sun-filled private deck, and an exquisitely renovated bath with dual vanities, rain-head shower, soaking tub, separate W/C, and a beautifully appointed dressing room with custom walk-in closets. Two additional guest suites complete the second level, each opening to a shared terrace overlooking the rolling lawn, shimmering pool, and Taylor Creek beyond. Outside, the property is a sanctuary unto itself. Wide lawns stretch toward the water, bordered by mature trees and lush, meticulously refreshed landscaping. The newly enhanced pool features an in-pool spa. It is anchored by a fully renovated pool house, offering a sitting area, changing room, separate shower, and WC-perfectly designed for days spent on the terrace or evenings entertaining at sunset. Additional amenities include two one-car garages, a spacious parking court, and complete privacy throughout the day as the sun moves across the property, reflecting off the water and grounds in a way that makes this home feel worlds away-yet it remains just moments from Southampton Village, world-class beaches, and everything that makes the Hamptons extraordinary. 344 Great Plains Road is more than a home-it is a rare south-of-the-highway estate offering quiet luxury, water views, and a lifestyle defined by beauty, comfort, and timeless Hamptons living.
