The approach to 18 Cornerstone Drive makes an impression before you ever reach the front door. A long paved driveway winds through 1.36 acres of beautifully maintained grounds, opening to a classic Colonial framed by mature landscaping and a welcoming covered front porch. Inside, generous living spaces unfold across three finished levels, offering room to gather, entertain, work, and unwind. The heart of the home is the impressive great room with soaring ceilings and a wood burning fireplace, while the dining room, kitchen, and dedicated office add versatility to the main level. Upstairs, the primary suite becomes a retreat of its own with a private bath featuring a soaking tub and stall shower, plus exclusive access to a massive loft with closet space overlooking the great room below. Three additional bedrooms complete the level. The finished walkout basement adds a den, recreation room, and full bath. Outdoors, a two tier Trex deck creates an inviting setting for dining and entertaining, overlooking the level, fenced backyard and expansive grounds. From mornings on the front porch to evenings by the fire or gatherings on the deck, this home offers spaces designed to be enjoyed in every season.
