This remarkable 5+ acre waterfront estate is one of the most extraordinary coastal offerings to come to market in generations. Perched on the southwest tip of an exclusive community, it is Cape Cod's southernmost private residential land. The property commands panoramic, unobstructed views across Buzzards Bay to Naushon and the Elizabeth Islands, and then onto Vineyard Sound and Martha's Vineyard. The estate features more than 611 feet of shoreline, anchored by a substantial protective seawall that ensures both privacy and structural permanence, as well as a private, pristine sandy beach. A charming three-bedroom cottage currently rests on the grounds, offering immediate enjoyment while serving as an unparalleled canvas for a world-class waterfront masterpiece. Future development allows for a two-story residence designed to capture expanded views toward Great Harbor, subject to local approvals.
