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.

A separate family room with fireplace and full bath, privately situated above the primary suite, offers an ideal accommodation for extended family or visitors. Ideally situated alongside some of Osterville’s premier boating facilities-including Nauticus Marina, Crosby Yacht Yard, and Oyster Harbors Marine-this location is particularly appealing for boating enthusiasts, offering convenient access to full-service docking and care. Just moments from Osterville Village, beaches, and waterfront dining, the property captures the essence of Cape Cod living in a highly sought-after setting.
