Perched directly on the dunes of East Sandwich, this striking residence enjoys a sandy beach on Cape Cod Bay as its backyard. Offered turn-key and fully furnished, the architectural heart of the home is a double-height great room with a wall of glass framing panoramic water views, wide plank oak floors, and a Town & Country gas fireplace. The open layout flows into a gourmet kitchen featuring custom black walnut cabinetry, natural quartz countertops, and professional-grade appliances. The first-floor primary suite provides a spa-like retreat with a hammered nickel soaking tub and Carrara marble, while three additional upstairs bedrooms also feature en suite marble baths. High-end details abound, from the mezzanine’s stainless steel cable railings and California Closets to the natural cedar roof with copper flashing. Outside, a sprawling deck with private stairs leads through the dunes to the sand, providing the perfect vantage point to watch the tide cross the iconic Sandwich flats.
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 2,282 sq ft principal dwelling). Lot size: 17,424 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 MLS and other third-party data may be inaccurate or out of date.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.
