    What's special

    Warm brick chimneySymmetrical windowsWelcoming arched entry
    Set gracefully back from the street, surrounded by acres of manicured lawns and gardens that can never be built on, and a 5-minute walk to a marina for your boat and kayaks to rent, this stately center-hall Colonial is 75-years-young and everything you picture when you dream of life in Westport Harbor. It’s one of 3-adjacent lots that add up to 12+ acres on the Westport River. A handsome bluestone walkway, framed by cobblestone borders, leads you to a welcoming arched entry — the kind of first impression that tells you you've arrived somewhere special. From the crisp white clapboard and classic black shutters to the symmetrical windows and warm brick chimney, every detail honors the timeless New England tradition, while the interior delivers the comfort and updates today's buyers crave. Inside, gleaming fully restored hardwood floors flow throughout, gracious formal rooms invite everything from quiet mornings to lively celebrations, and a cozy fireplace anchors the home with the kind of warmth that turns a house into a home. At the heart of it all is a beautifully renovated, sundrenched kitchen with high ceilings, and marble floor, thoughtfully designed for both the everyday and the extraordinary, and open to the spaces where you will actually live. Upstairs, four generous bedrooms offer restful retreats, including a spacious primary. All 2.5 bathrooms are newly renovated with Waterworks fixtures, walk-in-showers and modern new vanities – none have ever been used. Outside, the level, sun-drenched grounds, 20,000+ square feet, are a blank canvas for summer gatherings, garden dreams, or simply room to roam — all just moments from the harbor, the beaches, and the coastal lifestyle that makes this one of the most coveted addresses around. Room to add a pool, 2 bedrooms, and a 2-car garage. Available fully furnished. Homes of this caliber, in a location this special, are a rare find – the last time this one was for sale was half a century ago. This is more than a house — it's the Westport Harbor life you've been waiting for.
