About this home

A rare waterfront landmark offering the quintessential Duxbury lifestyle. Set on a protected harbor with direct access to Duxbury Bay, this exceptional property invites you to swim from your private dock, launch a kayak or paddleboard, and enjoy breathtaking sunsets from the expansive waterside deck designed for effortless entertaining.

The open-concept floor plan features waterviews, a custom wet bar, and seamless indoor-outdoor living. Multiple bedroom suites include a charming guest suite with a sleeping loft, while the primary retreat offers a walk-in closet, office area, and full bath.

Moments from Snug Harbor, Duxbury Harbor, beaches, and marinas, this is coastal living at its finest.
