Welcome to the highly sought-after neighborhood of Griswold Farms. Nestled at the end of a peaceful cul-de-sac, 121 Atwater Road offers a prime location with its backyard bordering Avon. This home was the developer's builder's choice when the subdivision was created, and it shows in every detail. This beautifully designed colonial boasts a range of desirable features. The main level invites you in with elegant tray ceilings in the formal living and dining rooms. The open-concept kitchen and family room create a warm, inviting space, complete with a cozy fireplace and easy walk-out access to the deck. Upstairs, the spacious primary bedroom suite includes a walk-in closet, a luxurious double vanity, a jacuzzi tub, and a separate shower. Three additional bedrooms offer ample space, with one featuring its own en-suite bathroom, plus an additional full bathroom in the hallway. The versatile office or workout room completes the upper level and can easily be converted into a fifth bedroom if needed. The basement, currently utilized for storage and recreation, includes a second fireplace and a walk-out slider, offering the potential to transform this space into additional living quarters of over 1,300sqft. Outside, you'll find a newer in-ground pool and a fenced backyard, perfect for outdoor enjoyment. The home is equipped with public water, public sewer, natural gas, and a new heating unit for your convenience.
