About this home

Room to spread out, space to come together, and flexibility for whatever life brings! Welcome to this spacious, 4 bedroom, 2.5 bath tri level home featuring a legally recognized accessory dwelling unit (ADU) with its own private entrance! Ideal for multigenerational living or a separate living arrangement, this versatile layout offers possibilities that are hard to find. The main home features a spacious kitchen, comfortable living areas, and a finished basement perfect for a game room, movie nights, or entertaining friends around the pool table. Fresh paint throughout, new carpeting in the in-law space, a roof that's just THREE years old, and a BRAND NEW septic system provide valuable updates. A convenient breezeway connects the two car garage to the main house, offering a welcome transition during New England's ever-changing seasons. Out back, an expansive deck stretches nearly the entire length of the home, overlooking a beautiful wooded setting. Enjoy summer days by the above ground pool, complete with a new pump and filter installed last year. And while Longley Road provides convenient access to surrounding towns, a side path connects the property to a quiet cul de sac neighborhood, with direct access to the Groton Rail Trail for walking, biking, and outdoor adventures. With flexible living arrangements, meaningful improvements, and nature right outside your door, this property offers a wonderful opportunity to make Groton home!
