The Waldorf Astoria Hotel & Residences in Miami is approaching topping out, with a design built around nine offset cubes that has created unusual structural and concrete construction challenges for the builder.

The project is identified in the source as a Waldorf Astoria Hotel & Residences tower and is being built in Miami, US.

Engineering News-Record reported that the tower’s form is driving the construction complexity, with the offset cube arrangement shaping how the structure and concrete work are being carried out.

The article frames the project as a supertall tower, and the report focuses on how the geometry of the building is influencing the construction process as it moves toward completion of the top section.

The source is Engineering News-Record, in an article published Oct. 21, 2026, titled “Miami Supertall Tower's Daring Design Takes Builders to New Heights.”

Why it matters for AEC

The tower’s geometry shows how highly irregular supertall designs can add structural and concrete execution complexity during construction. For AEC teams, the example underscores the delivery challenges that can come with pursuing distinctive massing at extreme height.

What this signal may mean for staffing or delivery capacity

The project’s unusual structural and concrete demands may increase coordination and technical workload for the construction team, which warrants monitoring as topping out approaches.
