New Construction | Water Mill South Just completed by boutique custom builder Heartwood Corp, this 7-bedroom, 9-bathroom, 9,600-square-foot Water Mill South estate showcases signature craftsmanship and refined detail. Positioned on prestigious Cobb Road behind a motorized gate and enveloped by mature, professionally designed landscaping, the property offers a private retreat moments from Flying Point Beach and Southampton Village. A soaring two-story foyer introduces the open, light-filled layout, highlighted by architectural floor-to-ceiling millwork on a double-sided gas fireplace shared with the living room. The dining area flows into a fully outfitted butler’s pantry with sink, ice maker, wine refrigerator, and walk-in pantry. The chef’s kitchen blends elegance and performance with custom white oak and painted cabinetry, integrated luxury appliances, and a hybrid waterfall island ideal for entertaining. The first-floor junior suite features a private patio, two walk-in closets, and a large spa-inspired bath with double vanity and privacy-glass shower enclosure that welcomes natural light. The living room, kitchen, foyer, and junior suite all overlook the landscaped grounds and pool, creating seamless indoor-outdoor living. A mudroom with garage access and a powder room complete the main level. Upstairs, the primary suite is a tranquil sanctuary offering two walk-in closets, a luxurious bath with soaking tub, separate vanities, makeup station, and privacy-glass shower and water closet, plus a dedicated office and serene views.
