Set on 10.65 acres in Southampton, this offering presents a rare combination of scale, flexibility, and forward-looking potential. Currently configured as a single expansive parcel, the property is in the process of being subdivided into four approximately 2.65 acre lots, each capable of accommodating a substantial residence with pool, pool house, and tennis. Offering rare versatility, a buyer could retain the full 10.65 acres to create a single private compound with meaningful acreage-- enough for equestrian or other uses requiring large lot space, an increasingly scarce condition in this market. Or they could choose to subdivide it other ways, depending on their needs. For example, they could create one large parcel and one or two smaller ones. And of course, they could move forward with the pending four lot subdivision and realize four distinct estate parcels. The subdivision is currently in progress with the Town of Southampton, positioning the next owner to benefit from the work already underway. The land itself offers a clean canvas for development, with the scale to support large homes and amenities while maintaining separation and privacy across each lot. Whether envisioned as a multi-generational compound, a strategic investment, or a boutique development opportunity, the property provides a compelling foundation. Opportunities of this size, with both immediate use and near-term subdivision potential, are limited within Southampton
