Summary
Ken Griffin, founder and CEO of Citadel, is pursuing the acquisition of a historic Miami cottage that would complete his assembly of an entire Brickell city block. Miami city commissioners are scheduled to consider selling the city-owned property at 190 Southeast 12th Terrace to a Griffin-affiliated LLC for $2.98 million. The 1905 white wood-frame cottage, built on a 6,000-square-foot lot with 1,800 square feet of interior space, is currently leased to the Dade Heritage Trust and appears on the National Register of Historic Places.
The property carries historical significance as the former office and surgical center of Dr. James M. Jackson, Miami's first resident physician who arrived in 1896. The Dade Heritage Trust secured a 10-year lease with a five-year renewal option in 2021, which was approved by the city commission after administrators scaled back an original proposal for a 90-year lease. Under the proposed sale terms, Griffin would assume landlord obligations and maintain the existing lease agreement with the heritage organization, according to city documents.
Griffin's pursuit of this final parcel completes an extensive and methodical real estate consolidation strategy in Brickell. Most notably, he acquired all 138 units of the 22-story Solaris condominium building, which Bloomberg reported represented an approximately $125 million outlay. That purchase left only the historic cottage standing between Griffin's control of the entire block. The cottage sits directly across from his planned Citadel headquarters location, making it strategically significant to his development vision. A Citadel spokesperson stated the company is in active discussions with both the Dade Heritage Trust and the City of Miami regarding a long-term preservation plan for the property.
This acquisition aligns with Griffin's established real estate investment philosophy. His team has indicated that acquisitions focus on "one-of-a-kind properties and oceanfront lots that are inherently of limited supply and therefore likely to keep increasing in value," while also targeting geographic areas where he maintains operational centers. Griffin's broader real estate portfolio exceeds $1 billion in value and spans multiple states and international locations, including Miami, Palm Beach, New York, Southampton, and London. As of January 2026, Griffin's estimated net worth stands at $51.2 billion, making him the world's 34th-richest individual.
