About this home

Introducing a one-of-a-kind opportunity to own a legacy estate south of the highway in Bridgehampton's farm country-120 Halsey Lane. This newly constructed, fully custom 14,267-square-foot residence is set on 2.5 lush acres and promises the pinnacle of Hamptons living. Newly Completed and Move in Ready, this architectural masterpiece will offer 9 bedrooms, 11 full bathrooms, and 3 half baths, designed to seamlessly blend modern luxury with timeless shingle-style elegance. Step inside to soaring spaces and grand proportions-an awe-inspiring 26' tall great room sets the tone for the rest of the home. Every inch of the layout has been thoughtfully curated: two true primary suites, one conveniently located on the main level and the other as a second-floor sanctuary complete with a private deck. From the oversized 3-car garage to the two elegant staircases and private elevator, no detail is overlooked. The lower level is an entertainer's dream featuring an 11' ceiling height, a golf simulator, full gym, sauna, steam room, and multiple bar and lounge areas. The main level continues the experience with massive covered patios perfect for indoor-outdoor living and seamless entertaining. Every room on the second floor is graced with 9' ceilings and stunning 12' cathedral vaulted designs, flooding each space with natural light and volume. The home's exterior matches the magnificence within, with beautifully manicured grounds, a 600-square-foot pool house, a resort-style swimming pool with spa, and a private tennis court-your own secluded Hamptons compound. This is more than just a home; it's a lifestyle-an extraordinary retreat built for generational enjoyment in one of the East End's most coveted locations. 120 Halsey Lane offers the rare combination of scale, style, and substance, with completion perfectly timed for summer 2026.
