About this home
Situated on an oversized lot in an excellent neighborhood directly across from Memorial Field, this spacious Custom Colonial offers an impressive combination of size, flexibility, and outdoor living. Extensively renovated and expanded, the home features generously sized rooms throughout, including a bright, oversized family room with a bow window and wall-mounted TV (included), along with a beautifully updated cherry kitchen featuring quartz countertops, stainless steel appliances, tiled backsplash, and abundant cabinetry. The first floor offers two adjoining rooms that provide excellent flexibility for bedrooms, a home office, playroom, or guest space. Upstairs, you'll find three bedrooms, including an expansive primary bedroom with a large walk-in closet, two additional bedrooms, and a bonus room currently utilized as a spacious dressing room/walk-in closet that could easily be converted into an additional bedroom, creating the potential for a six-bedroom home. Outside, enjoy the expansive fenced backyard with two gazebos, patio, hot tub, and plenty of open lawn space. Ideally located close to schools, shopping, dining, recreation, and major highways, this home offers an exceptional combination of space, convenience, and neighborhood appeal.
