About this home

The Trophy to a Boater's Dream on Mashta Island. What a Superb Location! Nestled on the N. side of Mashta Island in Key Biscayne, where privacy reigns. This rare gem features 100 linear ft of seawall with direct unobstructed access to Biscayne Bay and the Atlantic Ocean; perfect for boaters. The lot spans 15000 sf. It includes a Bali-style house built by Architect George Reed in 1965. The property also includes a pool, a 2 car covered carport. Whether renovating or building new, this is a once -in- a lifetime opportunity to own a prime waterfront on one of Key Biscayne's most prestigious streets. This is more than a home - it's a legacy property in one of Miami's most coveted island communities.
