Newly staged!!! This mint condition 3+ bedroom, 3.5 bath corner townhouse is offered for the first time since it was built in 2022. The space has been thoughtfully updated with custom built-in shelving and a striking Italian Aqua Blue matte tile surround framing the gas fireplace—complementing the sun-drenched living room's white oak floors. The chef's kitchen boasts Caesarstone counters, a 5-burner Bertazzoni range, 48" Thermador refrigerator, and Bosch dishwasher, flowing seamlessly into a dining area perfect for gatherings. The generous primary suite features abundant closet space and an en-suite bath with glass shower and premium fixtures. A well-appointed guest bedroom, third-floor bedroom with private bath, and flexible bonus room round out the living space. Step outside to your private patio retreat. Two parking spaces—one garage with storage, one deeded driveway—add everyday convenience. Constructed by a respected family-owned builder with roots dating to 1936.

ADU Potential

Massachusetts allows one accessory dwelling unit by right in single-family zoning districts statewide (M.G.L. c. 40A §3; 760 CMR 71.00, effective Feb 2025). Estimated maximum ADU size for this property: 900 sq ft (the lesser of 900 sq ft or half the 1,897 sq ft principal dwelling). Lot size: 1,897 sq ft.

Based on listing data, which indicates the property type — not the zoning district. Local dimensional, septic (Title 5), and historic-district requirements still apply. Not legal advice — verify with the municipality.
