      Townhouse Living in the Heart of Greenwich - Private Rear Lawn + 3,376 Sq Ft of Interior Space. A rare opportunity to own a beautifully scaled 3-bedroom, 3.5-bath townhome in one of downtown Greenwich's most charming and private enclaves. Set within a boutique six-residence association, 45 William Street #B is the largest residence in the community and the only one with its own private rear lawn - a 3,476-square-foot outdoor space that is exceptionally rare in central Greenwich. Inside, the home offers 3,376 square feet across three levels, blending the comfort and proportions of a townhouse with the ease of in-town living. The main level features gracious entertaining spaces, abundant natural light, a large eat-in kitchen, and seamless access to the rear lawn, creating an effortless indoor-outdoor flow for outdoor dining, entertaining, gardening, or simply enjoying private green space at home. Generous room proportions, three spacious bedrooms, three full baths plus a powder room, flexible living areas, and excellent separation of space provide comfort for everyday living, guests, and work-from-home needs. A private garage and additional deeded parking further enhance the home's convenience and livability. Ideally located just moments from Greenwich Avenue, shopping, dining, Metro-North, parks, and Greenwich Library, 45 William Street #B offers a truly uncommon combination of space, privacy, outdoor living, and close-to-town convenience.
