Extraordinary opportunity on a rare, near-acre lot, just two blocks from the heart of Newton Center, surrounded by mature growth trees and perched above a quiet dead-end street overlooking Newton’s largest conservation area. Seller is one of the area’s finest home builders, and welcomes offers that include Buyer requested renovations. A prime location with great convenience and proximity to everywhere in the Great Boston area, less than 15-minutes to Boston. This wonderfully designed contemporary family home has 6 bedrooms and an office with 4 full and 1 half baths. The thoughtful layout of the home has some unique features including: a 2-room en-suite 1st floor bedroom, a 2nd 1st floor bedroom, as well as a dedicated study/office; a large double height great room and dining room are the heart of the home that function perfectly for hosting large gatherings and holiday celebrations with family and friends; and on the 2nd floor there is a huge private primary suite with soaring ceilings, a large en-suite bathroom with steam shower and soaking tub, and a generous light-filled walk-in closet. The primary suite does NOT share any walls with any of the other bedrooms or living spaces providing for maximum privacy. The property itself is uncommonly desirable for its size and privacy, as well as its zoning. The home is not subject to historical review/control and allows from as much as 12,500SF above grade, so future owners have tremendous liberty to renovate and/or expand to make this home and property ideally suited to their taste and needs. Seller has construction plans for new garage with living/working space above that can be provided to a Buyer. A truly wonderful place to make your home!

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 5,399 sq ft principal dwelling). Lot size: 38,015 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.
