A rare opportunity to own one of Cambridge’s most discreet yet storied residences. Tucked away just blocks from Harvard Yard, 103 Irving Street was once home to legendary chef Julia Child, whose iconic kitchen is now preserved at the Smithsonian. The gracious home has since been thoughtfully renovated for 21st century luxury living while retaining the architectural detail and grand scale of another era. Beautifully proportioned spaces lend themselves to both everyday living and elegant entertaining. Understated amenities abound, including a well-equipped butler’s pantry that doubles as a caterer’s kitchen, Poggenpohl cabinetry, gas fireplaces, a wine room, Lutron lighting, and powerful solar panel system. Outside, professionally landscaped irrigated grounds are complemented by an expansive brick patio framed by a stone wall. A wide porte cochère at the end of a long driveway provides sheltered parking. Rich in history and ideally situated near restaurants, performing arts, museums, and universities, this remarkable property is truly irreplaceable.

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 6,321 sq ft principal dwelling). Lot size: 10,516 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 MLS and other third-party data may be inaccurate or out of date.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.
