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.
