About this home
A rare and extraordinary offering, this iconic beachfront estate stands as one of the finest properties on all of Cape Cod. Located in the heart of Hyannis Port, the stately colonial residence is perfectly set on magnificent grounds designed by the Olmsted Brothers, with mature trees, manicured hedges, and rolling lawns that give way to 410' of pristine sandy beach. From every vantage point across the property, mesmerizing views of Nantucket Sound, Hyannis Port Harbor, and Great Island provide a backdrop of unsurpassed natural beauty. This inimitable compound features a seven-bedroom main residence and a guest house with four bedrooms and two separate apartments with private entrance, providing refined accommodations for multi-generational living and staff. A once-in-a-lifetime opportunity, one of the most iconic estates on the Eastern Seaboard awaits its next chapter.
