Classic Colonial Elegance in Exclusive Avalon Estates! Nestled on over an acre of wooded grounds in Cumberland's desirable Arnold Mills neighborhood, this custom-built, single-owner 4-bedroom Colonial showcases solid construction, timeless character, and meticulous care throughout. The inviting family room features a skylight and brick fireplace, while the cherry kitchen with granite countertops opens through French doors to a formal dining room, flowing seamlessly into a spacious living room with a brick wood-burning fireplace. A magnificent cherry-paneled office with custom built-ins offers the perfect setting for working from home. A convenient first-floor lavette, laundry area, and generous mudroom/storage space off the garage add everyday functionality. Upstairs, the primary suite offers a walk-in closet and full bath, complemented by three generously sized bedrooms and a second full bath. The finished lower level provides abundant recreation space -ideal for a pool table, ping-pong, games, and gatherings- plus a walkout to the backyard. There is plenty of additional storage space in the unfinished part of the basement. Enjoy peaceful summer evenings and crisp fall nights on the screened porch overlooking the private, wooded setting. A whole-house generator adds peace of mind. A wonderful opportunity to own a lovingly maintained, quality-built home offering classic style, versatile living spaces, and a sought-after location!
