Set on Osterville's prestigious Sea View Avenue, this exquisite waterfront estate boasts an unparalleled combination of privacy, presence, and natural beauty. Sweeping views of Nantucket Sound and a pristine private sandy beach highlight this one-of-a-kind offering, located just minutes from everything Osterville has to offer.Accessed via a long, tree-lined driveway, coastal gardens and rolling lawns set the stage as one approaches the classic Cape Cod residence. Immediately upon entering, breathtaking views are on full display and continue throughout, with large windows and glass doors that seamlessly connect to multiple outdoor living spaces. At the heart of the home, a generously proportioned living room with three exposures is flooded with natural light, opening to a den on one side and a dining room on the other. Fit for any occasion, the dining room connects to the adjacent kitchen featuring an eat-in breakfast bar and water views. A guest bedroom completes the first level, offering convenience and flexibility. On the second floor, five additional bedrooms - including a spacious primary suite with mesmerizing vistas over Nantucket Sound - ensure ample accommodations for family and friends. Outside, the expansive lawn and terraces are ideal for embracing the outdoor lifestyle, while a staircase at the edge of the yard leads to one of Cape Cod's finest private sandy beaches. Just moments from The Wianno Club, Oyster Harbors, and the shops and restaurants of Osterville's Main Street, this rare and extraordinary property is ready to be enjoyed.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
