Legacy, Lifestyle & Opportunity - A discreet treasure in one of Cape Cod's most prestigious enclaves, this exceptional waterfront property offers rare access to legacy, lifestyle, and limitless potential. Originally part of a historic compound long held by the Mellon family and now by noted philanthropist and collector William Koch, the property stands as a rare opportunity to own a slice of coastal legacy. This waterfront estate offers 1.78 acres of private grounds, a beautifully preserved five-bedroom residence, and a substantial deep-water dock with direct access to Nantucket Sound--accommodating six or more vessels with ease. Inside, the home exudes understated charm with a seamless connection to outdoor living--screened porch, expansive deck, and water views from most rooms. A welcoming main-level primary suite with adjoining study anchors the floor plan, while the heart of the home features a stone fireplace, an open-concept kitchen, and a screened porch that opens to an expansive deck--perfect for entertaining or quiet reflection. Upstairs, guest bedrooms are enhanced by gracious proportions and stunning vistas. With additional buildable parcels from the same legacy estate also available, this is a rare opportunity to establish a private compound in one of New England's most exclusive waterfront enclaves. A sanctuary of coastal beauty and historic significance, all within the beloved village of Osterville - home to world-class golf, protected waters, and the timeless allure of Cape Cod.

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listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.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.
