Privately set behind a gated drive on two acres along Eel River, this remarkable Osterville waterfront estate commands a rare vantage point overlooking the river and Nantucket Sound. The architecture is designed around the setting, with broad expanses of glass, soaring coffered ceilings, fine millwork, and a succession of light-filled spaces oriented toward the water. The main level brings together a gracious chef’s kitchen, a dramatic great room overlooking the water, and a luxurious primary suite with its own media room. The residence unfolds across three levels, with a graceful stairway connecting each floor. The second level offers three additional bedroom suites, while the third floor creates a more intimate retreat, with a spacious waterfront sitting room opening to a private balcony, and a fifth bedroom along with two bonus rooms. The finished lower level is dedicated to recreation, with a theater accommodating 20 and a substantial game and media room. Beyond the main residence, the property takes on the character of a private coastal compound. A separate two-bedroom guest house with three-car garage and pool house overlooks the expansive pool and surrounding grounds. Multiple terraces and outdoor rooms lead toward the water, where a private sandy beach and substantial deep-water dock provide direct access to Eel River and Nantucket Sound. The setting is quintessentially Osterville: private, deeply connected to the water, and minutes from the village, its beaches, harbor, shops, and restaurants. With its scale, architectural pedigree, guest accommodations, and exceptional boating access, this is a distinctive waterfront offering in one of Cape Cod’s most sought-after enclaves.
