Plans for another major high rise at Miami Worldcenter are quietly grinding forward, with new federal filings now putting the project under aviation review. On May 21, 2026, FAA paperwork was submitted for a roughly 695-foot tower at 20 NE 8th Street in downtown Miami, part of Miami Worldcenter's Block E. The notices, filed by MWT X LLC, an affiliate of Lalezarian Properties, have triggered a formal aeronautical study by the Federal Aviation Administration. A City of Miami master construction permit filed in late February and accepted for review in March shows the proposal has already moved into the permit-review phase.
FAA filings put tower under aeronautical review
According to Florida YIMBY, the FAA submissions were logged as ASN 2026-ASO-8298-OE through 2026-ASO-8300-OE after being filed on May 21. The filings list a top elevation that translates to roughly 707–708 feet above sea level, which has prompted an FAA OE/AAA aeronautical study to assess any impact on navigable airspace. That review can end with a no-hazard determination or with conditions such as specific marking, lighting or design tweaks aimed at reducing risks for aircraft. In other words, the tower is now on the FAA's radar, literally and figuratively.
Design, height and public listings
The Council on Vertical Urbanism's SkyscraperCenter identifies the project as Miami World Towers 2B at 10–20 NE 8th Street, with an architectural height of about 694 feet and roughly 66 floors. The listing credits Nichols Architects as the tower's designer, consistent with renderings shared in earlier filings and public materials. The height numbers in the design listings and the FAA paperwork differ only slightly depending on measurement method, which is typical and helps explain why public documents reference both 694 and 695 feet for the same project.
Permit filing outlines program and price
City permit records reviewed by Florida YIMBY describe a 65-story multifamily rental tower with about 705 residential units, a 13-level parking garage and roughly 393,161 square feet of new construction. The estimated construction cost comes in near $220 million. The master construction application was filed on Feb. 25 and accepted for review on March 12, 2026, and is currently listed as under review pending applicant corrections. No general contractor is named yet on the active record, although Coastal Construction Group served as general contractor for the first phase of Miami World Tower, which is already complete. Whether Coastal returns for a sequel is one of several unanswered questions.
Where the tower fits in the larger plan
Block E sits within the 27-acre Miami Worldcenter master plan, a district that has rapidly filled in with towers, retail space and thousands of new units as downtown continues to densify. Reporting by CoStar and project materials outline Lalezarian's longer-term vision for multiple towers on Block E and nearby parcels. This latest filing is one more piece of that puzzle, and neighbors, transit planners and local businesses are likely to watch the FAA's decision and the city's permit review closely for clues on timing, construction logistics and any mitigation requirements.
What's next
The FAA's OE/AAA portal notes that aeronautical studies can run from several weeks to multiple months before yielding a formal determination that the developer must address prior to moving ahead with tall-structure construction. At the same time, the city permit remains under review, and developers typically need both a favorable FAA ruling and accepted, corrected permit filings before serious vertical construction can begin. For now, the filings by MWT X LLC and the active master permit application signal that Lalezarian is setting the stage for Block E's next major build phase, as Miami's downtown skyline keeps edging higher.
