Defined by its water views, generous grounds, and multiple outdoor living spaces, 30 Cockachoiset (”Dillon House”) offers a welcoming coastal retreat designed for gathering, entertaining, and enjoying life by the water. The main level is thoughtfully designed with an open floor plan anchored by a well-equipped kitchen that flows seamlessly into a sun-filled breakfast nook and sitting area, framed by walls of windows overlooking the water. Additional highlights include a living room with fireplace, formal dining room with custom built-ins, and a screened sunroom that invites indoor-outdoor living. The first-floor primary suite offers a private retreat with its own fireplace, water views, walk-in closet, and a spacious bath.
