Property Description
Experience the ease of condominium living in this beautiful, tastefully updated Colonial Square home. From the blooming perennial garden to the thoughtfully updated interior, this home offers exceptional flexibility. Special features include built-in maple cabinetry in both the dining room and front bedroom, which is currently used as an art studio. The kitchen has granite countertops, a subway-tile backsplash, stainless steel appliances, and an eco-silent Bosch dishwasher. The spacious first-floor primary bedroom suite has generous closets and a full bathroom. The living and dining areas are filled with natural light and character, highlighted by vaulted ceilings, hardwood floors, and a wood-burning fireplace that creates an inviting focal point. Just beyond, the tiled three-season porch overlooks the private landscape, while the adjoining deck is the perfect private spot to enjoy summer meals and evenings outdoors. For those not quite ready to part with the space of a single-family home, the finished walk-out lower level adds 1,289 square feet of versatile living and storage space. This level includes a guest bedroom suite with a kitchenette, a media room, a workshop, a three-quarter bathroom, and even more flexible space for hobbies, exercise, or an office. Sliders open directly onto the backyard, bringing in light and direct access to the outdoors. The home is equipped with a new electric heat pump installed in 2024 and central air. This is the opportunity you have been seeking: low-maintenance living just minutes from all that Peterborough has to offer, including downtown shopping, restaurants, a spa, gyms, theater, music, parks, trails, schools, a library, a town pool, a community garden, Cunningham Pond, Monadnock Community Hospital, and more. Open House on Saturday, May 23rd from 11-12:30.
