Welcome to 23 Old Westbury Road, an extraordinary private compound set on approximately 16 acres of fully landscaped grounds in one of Long Island's most prestigious enclaves. At its heart stands a ~10,000 sq. ft. Mediterranean-style brick mansion of commanding presence, complemented by seven additional legal residences, 14 garages, two large barns, and a U-shaped horse stable. The estate offers resort-level amenities, including an Olympic-sized heated in-ground pool of nearly 90,000 gallons with jacuzzi, a full outdoor kitchen, and manicured gardens designed for grand entertaining and tranquil living alike. Zoned for two acres with non-conforming use, the property presents a rare opportunity to subdivide or reimagine, unlocking tremendous value for a buyer seeking not only a remarkable lifestyle but also a sound investment. Whether envisioned as a multi-generational compound, equestrian estate, income-producing asset, or backdrop for film and media productions, this property offers versatility at a scale seldom seen. Perfectly situated just 30 minutes from New York City and minutes from public transportation, 23 Old Westbury Road delivers privacy, prestige, and long-term potential-an unparalleled acquisition for both use and investment.
