20 Madequecham Valley Road West #west
Six bedrooms, renovated in 2026.
Wake each morning to sensational Atlantic Ocean views, endless cool ocean breezes, and the soothing rhythm of the surf.
Surrounded by protected conservation and Land Bank land, this exceptional six-bedroom waterfront residence in Madequecham enjoys a full-acre setting with private deeded direct beach access, nearly 1,000 sqft of expansive ocean-facing decks, and the tranquility and privacy that define one of Nantucket's most treasured South Shore locations.
Light-filled living spaces capture the beauty of the Atlantic from nearly every vantage point, while a brand new construction lower level provides additional living space and guest accommodations. The expansive one-acre lawn presents a rare opportunity for the potential for an oceanfront pool.
Whether enjoying spectacular sunrises over the Atlantic, long days on one of Nantucket's most pristine beaches, or evenings beneath a sky full of stars with the sound of the surf just beyond the deck, this is a rare opportunity to own an exceptional waterfront home. Strong rental history further enhances its appeal as both a remarkable Nantucket getaway and investment opportunity.
