Perched at the pinnacle of Vose Hill in one of SOUTH WESTFORD'S most sought-after neighborhoods, this stately Colonial commands a premier, private 0.99-acre lot with exceptional curb appeal and a WRAPAROUND MAHOGANY PORCH. Inside, a thoughtfully EXPANDED KITCHEN pairs a Viking range, Sub-Zero refrigerator, and paneled Miele dishwasher with ceiling-height cherry cabinetry, granite counters, a center island, a bayed eating area, and two pantries. Custom hardwood floors with an ebony inlay flows into the bay-windowed dining room and first-floor office with French doors to the fireplaced family room. Upstairs, the primary suite features a walk-in closet with custom organizer and a renovated, spa-inspired bath with a quartz double vanity, glass-and-tile shower, and radiant heated floor. Three more bedrooms and an oversized full bath, plus an impressive BONUS ROOM with a nine-and-a-half-foot ceiling and Palladian window complete this level. Outside, a private oasis: a HEATED GUNITE POOL with plaster and tile refreshed in 2024, a bluestone patio, and a mahogany deck framed by mature plantings. Updates include a roof (2022), furnace, central air, and Andersen windows (bedrooms), with roughly 900 square feet ready to finish in the lower level. Title 5 passed. Minutes to Butter Brook Golf Club, the Bruce Freeman Rail Trail, Mass Audubon trails, top-rated Westford schools, and Route 110 shops and dining, with easy Route 495 access.
