About This Home

4390 Main

WATERFRONT ESTATE – Offered for the first time in 25 years, this rare Cape Cod retreat blends classic coastal architecture with modern refinement. Built in 1994 and refreshed with new siding and a Red Cedar roof (August 2025), the home offers 6 bedrooms and 5 baths. A chef’s kitchen with Viking professional gas range, Sub-Zero refrigerator, and center island with prep sink flows seamlessly into the sun-filled living room, dining area, and waterfront sunroom. The main residence includes a 2-car garage and full basement, while a versatile guest house with its own 2-car garage and striking fieldstone fireplace invites endless possibilities as a two-bedroom retreat, artist’s studio, game room, or workshop. Set on 3.8 private acres, the estate features a heated in-ground pool, landscaped grounds, and direct access to tidal waters. More than a residence, it is a private Cape Cod sanctuary offering beauty, privacy, and an unparalleled coastal lifestyle. Some photos virtually staged.
