Custom bow-front windows reflect the original design, and marble mantels, ornamental ceilings, medallions, and other period architecture remains intact throughout. The parlor level offers generous proportions and a series of connected living and entertaining spaces. Bow-front windows bring in natural light and frame views of the square, complemented by original fireplaces and beautifully preserved architectural details. The home includes four bedrooms, two full bathrooms, and two half baths, with a layout suited to both everyday living and entertaining.Modern updates have been incorporated throughout, including a well-appointed chef’s kitchen leading to a private patio and direct access to two parking spaces. This extraordinary home offers a distinctive example of historic South End living with the conveniences of today.
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 4,150 sq ft principal dwelling). Lot size: 1,870 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.
Estimates — not financial advice
These figures are illustrative estimates for informational purposes only — not an appraisal, valuation, or guarantee of rent, income, or returns, and not financial, tax, or investment advice. Rent is either the figure reported on the MLS listing — in-place rent that may differ from market and is not verified against the actual leases — or, where the listing reports none, an estimate from HUD Small Area Fair Market Rents, a government benchmark that may differ from actual market rent. Each figure is labelled with its source. Cap rate, NOI, and returns depend on the assumptions shown, which you can change. MLS and other third-party data may be inaccurate or out of date. Verify all figures independently and consult your own financial, tax, and legal advisors before making any investment decision.
