Waterfront new construction in one of Chatham's most preeminent locations, minutes from town. This rare half-acre offering on Emery Pond is to be built by R.A. Martin, one of the Cape's premier builders, with select interior finishes and customizations still available to the right buyer. New construction of this scale is exceptionally rare on Cape Cod, offering the perfect mix of estate-level living and an in-town lifestyle, all with stunning water views. The finished residence offers approximately 4,689 square feet of considered living space across three thoughtfully composed levels, with 4 bedrooms and 4 full baths. Sunlit interiors flow effortlessly from kitchen to dining to generous entertaining spaces, opening to a screened porch and deck framing sweeping views of the pond. Outside, a waterfront pool anchors a true outdoor retreat -- a private, resort-style setting for gathering, moments from town. A primary suite anchors the upper level alongside an office and two additional bedrooms, while the lower level offers a fourth bedroom suite and a generous recreation room. A rare opportunity to build new construction with a coveted mix of setting, space, and location on Emery Pond.
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 4,689 sq ft principal dwelling). Lot size: 24,100 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 MLS and other third-party data may be inaccurate or out of date.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.
