Description
Nestled on two private acres in the Incorporated Village of Nissequogue, this extraordinary estate offers beautifully reimagined living space where luxury, comfort, and timeless design come together. The home underwent a remarkable architectural transformation, completely reimagining the interior and exterior while preserving the character and presence of an established North Shore estate. Every detail was thoughtfully redesigned with an emphasis on exceptional craftsmanship, modern functionality, and elegant living. Rich white oak floors, custom stone surfaces, and exquisite finishes create an atmosphere that is both sophisticated and inviting. Designed for everyday living and exceptional entertaining, the chef’s kitchen features an expansive custom pantry that functions like a second kitchen, built-in wine storage, and a beautifully appointed wet bar. The dramatic great room, highlighted by soaring ceilings and a gas fireplace, serves as the heart of the home, while a separate entertainment room featuring a wood-burning fireplace with easy access to convert to gas provides additional space for gathering and celebrating. Offering six bedrooms and seven baths, including two luxurious suite options with spa-inspired baths, heated floors, generous walk-in closets, and refined finishes, the home provides exceptional flexibility and comfort. A distinctive spiral staircase leads to a charming tower overlooking the estate, creating a truly unique architectural feature. Beautifully integrated infrastructure and modern systems complement the home’s exceptional design, providing the comfort, efficiency, and functionality expected in a residence of this caliber. Outside, a heated saltwater pool with stadium steps and bench seating is surrounded by an expansive paver patio, creating the perfect setting for outdoor entertaining. Mature trees and thoughtfully designed landscaping enhance the privacy and beauty of the level two-acre property. A grandfathered horseshoe driveway with dual Belgian block entrances welcomes you home, a highly sought-after feature in Nissequogue’s renowned horse country. Located less than a mile from two beaches, including one with deeded access, this exceptional property offers a rare opportunity to enjoy luxury North Shore living in one of Long Island’s most renowned communities.
