This magnificent Hamptons estate is the setting for splendid living south of the highway. Set on 2.25A± gated acres in a private compound, the property encompasses 10,382A± square feet of living space with eight bedrooms, seven full and three half baths. Originally envisioned by acclaimed architect Val Florio and framed by award-winning landscapes from Edmund Hollander, the property was masterfully reimagined in 2019 and further refined with a renovation in 2022. Arrive through a gated entry to beautifully landscaped grounds and a three-car garage, where the home's classic architecture and refined scale make a striking first impression. Inside, a grand entry foyer introduces a flowing layout designed for entertaining. The formal living room with a fireplace overlooks the gardens, while a family room with a second fireplace and a formal dining room seating up to 16 offer multiple gathering spaces. A second, more intimate dining area complements the chef's professional kitchen, which is outfitted with top-grade appliances and ample prep space. There is also an ample first floor junior primary suite with access to the pool and patio. French doors open to covered porches, seamlessly blending indoor and outdoor living spaces. Upstairs, the tranquil primary suite is a private retreat, complete with a sitting area, a fireplace, a dressing room, and a spa-like bath featuring a soaking tub, radiant-heated floors, and a separate shower. The additional bedrooms are all generously scaled and beautifully appointed, each offering en-suite privacy. The finished, walkout lower level mirrors the amenities of a five-star resort, with flexible recreation space and wellness features. A spa-like environment includes a sauna, steam room, and massage room. Completing the lower level is a custom wine cellar. The 1,700A± square-foot guest house provides private accommodations with its own living quarters and a professional fitness and wellness center. Outdoors, the estate unfolds into a private resort. The grounds showcase a 55′ x 25′ heated gunite pool, complemented by a second beautiful 75' infinity edge lap pool, a separate spa, and an outdoor shower. A full-size all-weather tennis court with pavilion is framed by lush landscaping, while covered porches, terraces, and seating areas create endless opportunities for relaxation and entertaining. Located on a quiet cul-de-sac down a long private driveway just minutes from ocean beaches and the villages of Southampton and Bridgehampton, this is more than a home-it is a complete Hamptons compound, offering a lifestyle defined by luxury, leisure, and timeless design.
