About this property

Commanding 2 sprawling acres in the heart of Southampton, this masterfully designed new construction estate represents the pinnacle of Hamptons luxury. Room to build tennis or padel court. Spanning an impressive 9,600 +/- SF across 3 finished levels, the residence offers a rare combination of grand architectural scale and intimate, sophisticated comfort. With 8 spacious bedrooms and 10 bathrooms (8 full, 2 half), this home is perfectly engineered for both large-scale entertaining and quiet, private retreats. The light-filled interiors are defined by an open-concept floor plan featuring soaring ceilings, rich hardwood flooring, and a grand entry foyer that sets a tone of elegance. At the heart of the home, a gourmet chef's kitchen, complete with professional-grade stainless steel appliances, flows seamlessly into the formal dining and living areas. For those requiring a quiet workspace or a casual place to gather, the layout includes a dedicated den/office and a sun-drenched family room, ensuring there is a space for every mood and occasion. The exterior of the property is a private oasis designed for the ultimate summer lifestyle. An expansive deck overlooks the lush, manicured grounds and a magnificent gunite in-ground pool, offering the perfect setting for alfresco dining and poolside loungingplete with a two-car attached garage and modern amenities including central air and forced-air heating, this estate provides every convenience expected of a world-class Southampton residence. Ideally located and impeccably finished, this is a rare opportunity to own a significant piece of the East End.
