Privately set at the end of a long, winding drive, this exceptional Manchester-by-the-Sea estate spans more than 21 acres across Manchester and Gloucester, with sweeping lawns, mature gardens and beautiful views toward the Atlantic. Remarkably private yet moments from the village and coast, the property also enjoys deeded access across Summer Street to the beach. Originally built in 1917, the residence was extensively renovated and expanded, taken down to the studs while preserving its architectural character. Salvaged doors, fireplaces and historic materials—including marble from the nearby Coolidge Estate—were incorporated alongside new systems, windows, plumbing, electrical and HVAC. The result is an approximately 6,879-square-foot home that feels established, warm and timeless.Beautifully scaled interiors feature custom millwork, eight fireplaces and inviting spaces for both entertaining and everyday living. The renovated kitchen opens to informal dining and sitting areas, complemented by a living room, library, formal dining room and fireplaced family room. The primary suite offers a fireplace, luxurious bath, dressing room and private deck, with four additional bedrooms and a third-floor recreation room. Outside, rolling lawns and colorful gardens surround a saltwater Gunite pool and spa with ocean views. A newly built 621-square-foot pool house, centered around a striking antique fireplace, features vaulted ceilings, warm wood finishes, a full kitchen, bath and dedicated laundry. Substantial yet welcoming, this extraordinary estate combines privacy, historic character and relaxed North Shore living.
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 6,879 sq ft principal dwelling). Lot size: 939,589 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.
