- • The estate occupies prime ocean-to-lake frontage on South Ocean Boulevard, approximately a quarter mile south of Mar-a-Lago, positioning it as the largest contiguous property holding in Palm Beach with 871 feet of oceanfront exposure.

Summary
The centerpiece of Griffin's estate development plan centers on an oceanfront mansion spanning approximately 44,000 square feet, designed for occupancy by his mother, family members, and guests. The Palm Beach Architectural Commission granted design approval for this residential structure in late June 2022, with construction planned for the northern section of the property fronting South Ocean Boulevard. This mansion project will utilize roughly 8 acres of the assembled landholding.
The estate's strategic positioning places it approximately a quarter mile south of former President Donald Trump's Mar-a-Lago compound along the coastal stretch informally known as "Billionaires Row." The property commands 871 feet of oceanfront exposure and represents the largest single estate in Palm Beach's real estate market. Griffin's acquisition approach—purchasing multiple individual parcels through separate legal entities—allowed him to systematically consolidate fragmented holdings into a unified, premium development site.
Griffin's Palm Beach real estate commitment occurs concurrent with his broader relocation of Citadel's operational headquarters from Chicago to downtown Miami, a move he has publicly confirmed. Despite the corporate relocation and family move to Miami, Griffin maintains substantial financial exposure to Palm Beach real estate, underscoring the continued appeal of coastal Florida properties for ultra-high-net-worth investors managing multi-billion-dollar asset bases.
