Custom-Built Colonial • In-Law Suite • 6.15 Acres | Nestled on 6.15 acres, this custom-built home offers a rare combination of space, privacy, and flexibility. Meticulously maintained by its original owners, the property features over 4,200 square feet of living space, including 5+ bedrooms, 3.5 baths, a four-room main-level in-law suite with its own laundry, ideal for multigenerational living, and an attached three-car garage with access to both living areas. Step inside to an elegant two-story foyer leading to the home's thoughtfully designed floor plan. The heart of the home is the spacious custom kitchen featuring granite countertops, abundant cabinetry, a walk-in pantry, coffee bar, and an open layout that flows seamlessly into the dining and family rooms.
