Property Description
Set within the Graceland Farms neighborhood, this custom Colonial has been thoughtfully remodeled to deliver both classic charm and modern ease. Sunlight pours into an open floor plan where hardwood floors run throughout, creating a seamless and polished feel from room to room. The heart of the home is the kitchen designed with entertaining in mind. Stainless steel appliances, a generous pantry, and an 8-foot center island anchor the space, while granite countertops add a refined, understated elegance. A 6-foot built-in workspace with a beverage cooler and glass-front cabinetry offers the perfect setting for everything from morning coffee to evening cocktails. On the main level, the living room and family room, each with its own fireplace, can easily adapt to your lifestyle. A home office, mudroom, and powder room round out the first floor. Upstairs, the primary suite provides a true retreat, featuring dual walk-in closets and a spa-inspired bath with a double-sink granite vanity, soaking tub, and glass-enclosed shower. Three additional bedrooms, two full baths, and a bonus room with skylights and its own staircase offer space for guests, hobbies, or a second office. Outdoor living is just as compelling. A deck overlooks a level, private backyard with plenty of room for a pool, gatherings, or simply unwinding at the end of the day. Only five miles to the village of Madison and the shoreline at Hammonasset Beach - close to everything while feeling a world apart. Agent owner.
