Related Group has refiled Federal Aviation Administration height permits for its long-delayed third and final tower at One Brickell, signaling renewed movement on the final phase of the three-tower master plan along the Miami River. The FAA filings confirm a previously approved height of 897 feet above ground, or 901 feet above mean sea level, for the tower proposed at 444 Brickell Avenue. The refiling follows the expiration of height permits originally submitted in 2022 and does not indicate any changes to the project’s approved height or overall configuration. The tower was previously designed by Arquitectonica, planned to rise 80 stories, and programmed to contain approximately 420 residential units.
The site is currently occupied by a 13-story office building completed in 1972. The structure contains approximately 344,187 square feet of office and retail space and includes The Capital Grille at the ground floor. Portions of the building are currently used to store archaeological materials recovered during earlier excavation activity on the One Brickell site.
According to reporting in late 2024, demolition of the existing office building is not expected to occur until at least 2028. Related Group has indicated that selected archaeological artifacts will be incorporated into the future development, following approaches used in the Riverwalk components of the adjacent towers, including designated exhibition areas acknowledging the history of the Tequesta Tribe.
The 444 Brickell parcel has remained dormant for several years after expansive Tequesta artifacts and human remains were uncovered during excavation of neighboring sites within the One Brickell development. Those discoveries resulted in prolonged archaeological review and preservation discussions, contributing to delays on the final tower while construction advanced on adjacent parcels now occupied by Baccarat Residences and Viceroy Brickell.
As a result of the findings, the site was designated Archaeologically Significant. The designation requires enhanced oversight of excavation activities and mandates careful documentation, storage, and potential public display of archaeological materials. Miami’s Historic and Environmental Preservation Board retains review authority and may issue recommendations regarding how artifacts are managed during construction.
The designation does not prohibit development. Related Group retains vested development rights granted prior to the discoveries, allowing the project to proceed under existing approvals. However, any substantial changes to the approved plans, including modifications to height or design, would likely require resubmission and could trigger additional review and public process.
While updated plans have not been publicly released, prior renderings depict the tower with a massing and architectural expression closely aligned with both the Baccarat Residences and Viceroy Brickell towers. The visuals suggest a cohesive design language across the three-tower One Brickell master plan, with the third tower rising taller than its neighboring components.
