Miami’s First Supertall Reaches Historic Halfway Mark, 50 Floors and Four Cubes Now Stand

February 9, 2026

The Miami skyline is undergoing a monumental transformation as the Waldorf Astoria Hotel & Residences Miamiofficially hits its halfway milestone. Standing at 300 Biscayne Boulevard, the tower has successfully completed the concrete pour for its 50th floor, marking the midway point of its vertical ascent to becoming Florida’s first supertall skyscraper

Once completed, the Waldorf Astoria will soar to a height of 1,049 feet (319.7 meters). This stature earns it the “supertall” designation—a category reserved for buildings exceeding 300 meters—and will make it the tallest residential building south of New York City.

The project is a collaboration between Property Markets Group (PMG), Greybrook, Mohari Hospitality, S2 Development, and Hilton

Designed by Sieger Suarez Architects in partnership with Uruguayan architect Carlos Ott, the tower’s silhouette is unlike anything else in the region. The structure consists of nine offset glass cubes that appear to spiral upward.

Progress Update: As of early 2026, four of the nine cubes are structurally complete and visible against the skyline.
Construction Pace: Work is moving at a brisk average of one floor every 10 days.
Facade: Glass cladding has already begun to wrap the lower sections, giving onlookers a real-world look at the reflective “skin” that will eventually define the 100-storey landmark.

The mixed-use tower is set to house 387 private residences and 205 hotel guest rooms. Notable features include:

Peacock Alley: A signature Waldorf Astoria social space featuring a massive three-story Foucault pendulum.
The Amenities: Residents will have access to a private pool deck, a holistic wellness spa, and high-tech “smart building” integration via a custom app.
The Views: Due to its height and offset design, the building offers unobstructed 360-degree views of Biscayne Bay, Miami Beach, and the Atlantic Ocean.

While the original goal targeted 2026, the current construction trajectory points toward the tower topping off in late 2026 or early 2027, with an official opening expected in 2028. Despite the wait, the project is already a commercial juggernaut, with reports indicating it is more than 90% sold.

As the fifth cube begins to take shape, the Waldorf Astoria is no longer just a rendering; it is a visible signal that Miami’s “Manhattanization” has reached a new, record-breaking altitude.
