There are homes you visit, and there are homes you never want to leave. Rich in character & thoughtfully reimagined, this classic residence is the latter. A rare blend of timeless architecture, designer-appointed details, & easy living just minutes from the train, schools and vibrant Greenwich Avenue. The first floor features a gracious dining room that frames the backyard through an oversized picture window, while a warm and inviting family room, accented by exposed beams and a wall of sliding glass doors, creates a seamless connection to the outdoors. At the heart of it all is a carefully curated chef's kitchen, including a sun-washed banquette wrapped in windows; the perfect spot for morning coffee & everyday dinners. Just beyond, an expansive flagstone terrace extends the living space outdoors, complete with a porch swing, lounging space and a dining area made for long summer evenings. A bonus sunroom offers its own escape, framed on two sides by peaceful views over the terrace, yard and Horseneck Brook. Four fireplaces warm the main house, adding timeless charm throughout. Upstairs, five generously proportioned bedrooms and four full baths fill the main house. Adding exceptional flexibility, a beautifully decorated 1,708-square-foot 2 story guest cottage, complete with its own family room with fireplace, kitchen, bedroom and two full baths, offers a private retreat for guests or family. This is a rare opportunity to own a piece of classic architecture, fully reimagined for the way you live today.
