What's special

Tucked at the end of a private road in Cos Cob, this newly built (2025) Louis Contadino-designed home offers a layout rarely available in central Greenwich at this price point: sophisticated single-level main-floor living over a fully finished walk-out lower level, all on a private 0.34-acre setting. The main floor delivers four bedrooms -- three with private en-suite full baths, including a primary suite with soaking tub, double vanity, and heated floors. The chef's kitchen features Sub-Zero and Wolf appliances, custom cabinetry, marble counters and backsplash, a white oak island, and a walk-in pantry, all opening to a light-filled great room and formal dining. Wide-plank white oak flooring runs throughout. Below, a generous family room with full bath and direct yard access expands the home for guests, entertaining, or future flexibility. Approximately 3,500 square feet of finished living space in total, with available FAR for roughly 1,000 square feet of additional expansion if desired. Outside, extensive stonework frames the entry, terrace, and grounds, with four-zone HVAC and EV charging completing a thoughtful modern build. Set high above a quiet private road yet minutes from the village, train, and I-95, the property offers the privacy of an estate in a location that keeps you fully connected to Greenwich. Vision, design, and execution complete -- a finished home, ready to move into.
