    What's special

    Tucked at the end of a quiet cul-de-sac in one of Greenwich's most coveted school districts, this beautifully updated 4-bedroom home delivers the rare combination of move-in condition and real upside. The fully reimagined primary suite stuns with high-end marble, dual vanities, and a custom walk-in closet. Open-concept kitchen and family room -- anchored by one of two fireplaces -- flow through French doors to expansive new decks. The second level offers three bedrooms and two full baths, including a serene ensuite. A renovated basement delivers flexible living space for a gym, office, or playroom. Two-car attached garage, updated appliances, tankless water heater, split A/C, and generator check every box. Over 1,000 SF of expansion potential awaits. North Mianus Elementary.
