Ken Griffin’s Citadel has filed a key shoreline review for its revised 52-story Miami headquarters, transitioning the $2.5 billion project to office space.

Updated Oct. 8, 2026. On Sept. 14, an 85-foot drilling rig used for soil-improvement work at the site toppled into Brickell Bay Drive, sending three workers and a motorist to hospitals with injuries officials described as minor, ENR reported. OSHA opened an investigation. Miami-Dade County issued a stop-work order and requires a safety plan before construction resumes. As of Traded's Sept. 22 report, county officials had not announced a date for lifting the order. The schedule described below reflects plans before the accident.

On July 2, 2026, Ken Griffin's Citadel and Related Companies advanced their planned 52-story Brickell office tower by submitting a shoreline review application. The filing moved the $2.5 billion headquarters project forward as developers prepared for vertical construction in late 2026.

Regulatory Milestones on the Bayfront

Law firm Akerman LLP filed the request for a "No Need to Comply" determination on July 2, 2026, targeting Miami-Dade County's Biscayne Bay Shoreline Development Review process. The filing asks the county to confirm that the development already meets the shoreline standards for the Rapid Transit Zone Metromover Subzone, including the approved waterfront setback, required view corridors and a public baywalk.

The property at 1201 Brickell Bay Drive sits within the Metromover Subzone of the Rapid Transit Zone. Under these guidelines, the project avoids municipal minimum parking mandates. The developers will build 40 executive parking spaces.

In December 2025, the Miami-Dade County Board of County Commissioners approved the project's General Development Plan. The commissioners also approved a non-use variance that permits a 40-foot waterfront setback. This variance reduces the standard 50-foot setback requirement along the Biscayne Bay shoreline.

Design Revisions and Budget Escalations

The design team, led by Foster + Partners and architect of record AAI Architects, revised the building plans in mid-2026. The developers changed the project from a mixed-use development into a dedicated office tower. In April 2026, Commercial Observer reported that the developers were scrapping a planned 212-room luxury hotel on the upper floors and turning the 1.7 million-square-foot tower into a stand-alone office building.

The revision also altered the height of the tower. Revised plans submitted in mid-2026 reduced the elevation to 958 feet. The Federal Aviation Administration had approved a supertall height of 1,049 feet. This reduction drops the building below the internationally recognized 984-foot supertall threshold.

The Foster + Partners design features a tapered tower profile supported by exterior structural elements. These structures allow for column-free interior floor plates. The design maximizes natural light and bayfront views. It includes impact-rated glazing engineered to withstand high-velocity hurricanes. The tower also incorporates multi-level open-air terraces with native South Florida plants, offering space for outdoor meetings. A multi-story pedestrian podium will sit at the base of the tower, providing dining options and retail spaces along the public baywalk.

Project costs have escalated. The estimated budget for the headquarters has increased from its original $1 billion projection to $2.5 billion. To manage the financial and logistical scope, Citadel parted ways with Chicago-based Sterling Bay in 2023. The firm brought on New York-based Related Companies as a co-developer in January 2025.

Timeline and Active Groundwork

Crews began site preparation in March 2026. Under an $11 million soil improvement permit, contractors started deep soil mixing to stabilize the waterfront site. The development team filed foundation permit applications in mid-May 2026, and the team was targeting vertical construction in the fourth quarter of 2026. That target predates the September stop-work order described in the update above.

Citadel and Citadel Securities will occupy one-third of the office space, totaling 561,000 square feet. The joint venture plans to lease the remaining floors to external corporate tenants. Citadel’s roughly 500 Miami employees work from temporary offices at the 830 Brickell tower, where Citadel leases several floors, according to Bisnow and Miami New Times.

Expanding the Footprint and Regional Friction

Griffin acquired the 2.5-acre bayfront parcel in April 2022. He purchased the land for $363 million from Tibor Hollo’s Florida East Coast Realty. Griffin has since expanded his real estate footprint in the immediate area. In mid-2026, he completed a buyout of all units in the 22-story Solaris condominium across the street from the development site. Griffin plans to demolish the residential building, Miami New Times reported. Miami New Times describes his assemblage around the Solaris as 4.2 acres, while the Miami Herald reported that the Solaris purchase gives him about five acres in the area.

According to local planning documents, the broader master plan includes a 300-unit residential apartment building and a 1,420-space parking garage on these adjacent parcels. These buildings will support the primary office tower.

The expansion in Miami followed a political dispute in New York. In April 2026, New York City Mayor Zohran Mamdani filmed a video outside Griffin’s $238 million Manhattan penthouse to promote a proposed tax on second homes worth more than $5 million, ABC7 New York reported. Citadel objected to the video, and Commercial Observer reported that Griffin was weighing a larger footprint for his firms at the Miami tower. The Real Deal reported that the office expansion was planned before the dispute. Details regarding the design and zoning adjustments are documented on Florida YIMBY.

Foster + Partners leads the design with AAI Architects as architect of record, and the base adds dining and retail along the public baywalk.

What is the construction timeline?

Site preparation began in March 2026 under an $11 million soil improvement permit, and foundation permit applications were filed in mid-May 2026.
