Nestled on one of Key Biscayne’s most exclusive streets, this island estate boasts 300+ FT of waterfront on a peninsula, with a sweeping 180-degree panorama of sunsets over the Cape Florida State Park. Ideal for Boaters, it accommodates a 100+ FT yacht & direct Biscayne Bay access. The 29,100SF lot equals two waterfront lots by Key Biscayne’s standards, also allowing for jet skis, kayaks, paddleboards & open green space for kids’ play. Enjoy added privacy with no neighbors across the waterway, frequented by dolphins & manatees. This family-friendly home has a Feng shui design that creates a harmonious flow of energy & allows for a constant breeze, best enjoyed from the gazebo. Designed for resort-style living with exceptional indoor-outdoor spaces, it's the ideal retreat for island living.
