Better than new construction, this meticulously maintained 4-bedroom colonial in Brookline, NH, features a backyard oasis and premium upgrades throughout. The first floor offers a bright and welcoming foyer leading to a spacious kitchen with stainless-steel appliances, granite countertops, and large island with an overhang for additional seating. The main level also includes a generously sized and bright living room with a gas fireplace, a formal dining room, convenient first floor laundry room, and a half bath. The second floor boasts a large primary bedroom with a walk-in closet, an ensuite full bathroom, and direct access to the large, finished bonus space above the garage, currently being used as a home office. Three additional bedrooms and another full bathroom complete the second floor. The finished basement offers additional living space and flexibility, with space currently used as a spare bedroom, while the unfinished section provides excellent storage options. Outside, you'll find a fully fenced backyard featuring a large deck with composite decking that steps down to an expansive patio, a newer swim spa, extensive ambient light setup, a shed for extra storage and ample space for gardening. Additional upgrades and improvements include an upgraded irrigation sprinkler system with digital rain sensors, central A/C, Rinnai on demand hot water heater, generator hookup, security lights and cameras, keyless entry, and a sizeable attached two-car garage. All situated on a private 2.45-acre lot with convenient access to local amenities.
