Ken Griffin Proposes Exclusive Private Marina on Terminal Island, Miami Beach
Billionaire investor Ken Griffin has unveiled plans for a private superyacht marina on Miami Beach’s Terminal Island: no doubt angling to forge the exclusive retreat designed to accommodate his personal fleet and further expand his growing South Florida real estate portfolio.
The proposed 30,000-square-foot marina, located at 120 MacArthur Causeway, sits on a 3.7-acre waterfront parcel overlooking PortMiami. According to design firm BMA Architects, the project, known as One Island Park, will redefine private maritime luxury through a collection of four architecturally distinct buildings, each serving a dedicated purpose within the secure compound.
An Ultra-Private Haven for Superyachts
The Miami marina plans include a gatehouse and security pavilion, a crew facility featuring a full kitchen, laundry, gym, sauna, and rooftop pool, and an owner’s pavilion complete with a private lounge, storage suites, and a second pool for relaxation and entertaining. An operations center will house staff offices and a workshop for yacht maintenance and technical support.
The marina itself is expected to include three to six berths capable of accommodating some of the world’s largest yachts—including Griffin’s own 308-foot superyacht, Viva. Designed strictly for private use, the facility will not be open to the public but may host exclusive events during marquee gatherings such as Art Basel and the Miami Grand Prix.
A Landmark Development in Miami’s Evolving Waterfront
Griffin’s proposal will go before the Miami Beach Planning Board for conditional use review on November 4, 2025, with concurrent evaluation by the Miami-Dade Shoreline Review Committee.
The property spans approximately 1,400 feet of shoreline and has a storied development history. Once owned by The Related Group, earlier plans for an office complex were later abandoned. Lincoln Property Company acquired the site in 2023 for $77 million USD, with ownership records since updated to reflect Griffin-affiliated entities.
An Expanding South Florida Portfolio
The marina adds another layer to Griffin’s expansive South Florida holdings. In 2022, he relocated Citadel and Citadel Securities headquarters from Chicago to Brickell and later announced a $2.5 billion bayfront complex at 1201 Brickell Bay Drive—featuring office space, a luxury hotel, and world-class dining.
Griffin also owns residences on Star Island and a $106.9 million Coconut Grove estate, underscoring his deep investment in Miami’s ascendant luxury landscape.
Private Dock, Public Impact
While conceived as a private marina, Griffin’s One Island Park represents the ongoing transformation of Miami Beach into a global capital for superyachts and ultra-luxury waterfront living. Combining architectural excellence, maritime engineering, and exclusivity, the development further cements South Florida’s status as the world’s next great destination for modern yachting culture. Announced on the eve of Fort Lauderdale International Boat Show, it's sure to build some buzz. ⛵︎
