About This Home

155 Irving Avenue

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. Immediately upon entering the residence, unobstructed vistas take center stage and continue throughout each room. Grand gathering spaces seamlessly connect to the outdoor living areas, with thoughtful proportions and scale for every occasion. The light-filled kitchen includes an informal breakfast area and direct access to the pool and waterside terrace. In the study and wet bar, rich millwork and exquisite craftsmanship lend a sense of warmth that carries into the formal dining room. A luxurious primary suite and six well-appointed guest bedrooms provide refined accommodations for all. This inimitable legacy estate is steps from the West Beach Club and Hyannis Port Yacht Club, with Cape Cod's best golf courses, deep-water marinas, Cape Cod Gateway Airport, and ferry service to Martha's Vineyard and Nantucket just minutes away. A once-in-a-lifetime opportunity, one of the most iconic estates on the Eastern Seaboard awaits its next chapter.
