Summary
Billionaire Ken Griffin is pursuing acquisition of a city-owned historic cottage in Miami's Brickell neighborhood for $2.98 million, marking the final piece of a methodical real estate consolidation strategy centered on his hedge fund Citadel's new headquarters location. Miami city commissioners are scheduled to vote on the proposed sale of the property at 190 Southeast 12th Terrace, a white wood-frame cottage constructed in 1905 that is listed on the National Register of Historic Places.

The structure carries significant historical weight: it formerly housed the office and surgical center of Dr. James M. Jackson, Miami's first resident physician who arrived in 1896. The property encompasses 6,000 square feet of land with an 1,800-square-foot building currently leased to the Dade Heritage Trust, a nonprofit organization that has maintained its headquarters there since 1978. The trust signed its current lease in 2022 under terms negotiated following city commissioners' 2021 decision to scale back a proposed 90-year lease to a 10-year term with a five-year renewal option.

Griffin's acquisition strategy reflects a deliberate approach to block consolidation. He previously purchased all residential units of the adjacent 22-story Solaris condominium, which he plans to demolish for future development. The cottage acquisition would eliminate the last remaining property preventing Griffin from owning the entire city block opposite Citadel's future headquarters. According to Bloomberg's earlier reporting, the Solaris purchase positioned Griffin one property away from total block control.

A key condition of the sale requires Griffin to maintain the existing lease with Dade Heritage Trust and assume all landlord obligations following closing, preserving the nonprofit's operational continuity. Citadel's spokesperson stated that the company is actively engaged in discussions with both Dade Heritage Trust and the city of Miami regarding a long-term preservation plan, suggesting an intent to balance development ambitions with historical stewardship considerations. The timing and strategic sequencing of acquisitions underscore Griffin's long-term investment thesis in Miami real estate as a hedge fund operator establishing significant operational presence in the city.
