An exceptionally rare offering in the heart of Southampton Village, this custom-designed concrete residence was masterfully built by its owner, Nicholas Alimanestianu, a renowned Hamptons general contractor celebrated for designing distinguished homes and commercial spaces since 1984. Set on a generous quarter-acre, the property strikes the ideal balance of space, style, and village convenience, combining architectural integrity with a level of craftsmanship rarely found in today's market. Constructed with solid cement walls and crowned with a striking copper roof, the 6,000-square-foot home spans three light-filled floors-each easily accessed by a private elevator-and is bathed in sunlight from expansive imported mahogany windows and doors sourced from Belgium and across Europe. Every room exudes warmth, quiet elegance, and a sense of enduring quality, creating a home that feels both sculptural and deeply inviting. Designed with remarkable flexibility and potential, the residence is ready to be reimagined as a six-bedroom modern retreat, with a fully finished lower level offering additional recreation or living space. Updated AC zones ensure year-round comfort, while the sun-filled two-car garage provides secure parking framed by natural light. Outside, the property transforms into a private oasis centered around a striking 43' x 9' in-ground pool-an elegant, architectural focal point perfect for summer relaxation and entertaining. Combining enduring concrete construction, European-imported materials, thoughtful design, and a premier Village location, this home stands as a rare Southampton gem. Just moments from the white sand beaches, cultural institutions, and the shops and dining of Main Street, it offers a unique opportunity to enjoy Southampton Village living, elevated to its highest expression.
