Beyond a gated approach and long gravel drive, 672 Halsey Lane unfolds as one of Bridgehampton South’s rarest offerings, a true legacy estate where scale, privacy, and setting converge in a way that almost never comes to market. Set on 1.96 manicured acres with an additional 4-acre reserve owned by the property itself, this extraordinary +/-15,000 square foot residence lives against a backdrop of protected open land and neighboring horse farm vistas, creating an atmosphere that feels worlds away while remaining moments from ocean beaches, village dining, and the very best of the Hamptons. With western exposure stretching across the reserve, the home is drenched in golden sunset light every evening, an ever-changing view that defines the property’s unmistakable sense of serenity. Designed for both grand-scale entertaining and intimate everyday living, the estate offers nine bedrooms, eleven full baths, and two half baths across beautifully crafted interiors filled with warmth, volume, and timeless elegance. A dramatic double-height foyer introduces a series of beautifully proportioned living spaces, including a formal living room with fireplace, an inviting den with its own fireplace, a stunning office, and a chef’s kitchen designed as the heart of the home. Throughout the residence, ten fireplaces add character and ambiance, while walls of glass frame sweeping reserve views from nearly every principal room. The second-floor primary suite is its own private retreat, complete with a separate living room, dual fireplaces, private terrace access, and a spa-like bath with radiant heated floors. Equally impressive, the first-floor primary suite offers its own office and seating area, two fireplaces, and radiant heat in the bathroom, perfectly designed for comfort and privacy. Additional amenities rival those found in world-class resorts, including an elevator servicing all levels, a professional gym with sauna and steam shower, movie theater, temperature-controlled wine cellar, and three separate laundry rooms for effortless functionality. Outdoor living is equally compelling. Two expansive rear decks overlook the endless reserve and capture some of the most spectacular sunsets in Bridgehampton. The heated pool and tennis court are positioned within beautifully landscaped grounds, while the fully equipped pool house serves as a destination of its own with a kitchenette, two fireplaces, private laundry, seating lounge, and a sprawling loft space above. Completing the estate is a four-car garage and an unparalleled sense of privacy rarely found south of the highway. Trophy properties are defined not simply by size or amenities, but by the feeling they create and the impossibility of replicating them. 672 Halsey Lane is exactly that, a generational Bridgehampton estate offering land, scale, protected reserve views, and timeless luxury in one of the Hamptons’ most coveted locations.
