A work of art—this stunning, one-of-a-kind contemporary new construction is perfectly sited on a beautiful, level lot in one of Sudbury’s most prestigious locations. Bathed in natural light, the home features soaring ceilings, striking architectural lines, and a thoughtfully designed open floor plan that balances flow with privacy. A dramatic two-story family room, highlighted by a wall of windows and a floor-to-ceiling fireplace, opens seamlessly to a state-of-the-art custom kitchen with waterfall island, top-tier appliances, walk-in pantry, and sun-filled breakfast area with sliders to an oversized deck overlooking a spectacular backyard abutting conservation trails. Includes a formal dining room and private office. Luxurious first- and second-floor primaries offer fireplaces, walk-in closets, and spa-like baths. Four more bedrooms, most with en-suite baths, laundry room, and a walk-out lower level w/game room, bar, theater, gym, full bath, and ample storage. Ideal commuter location.

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 7,947 sq ft principal dwelling). Lot size: 134,962 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 MLS and other third-party data may be inaccurate or out of date.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.
