Downtown Miami's skyline is rising fast. The Waldorf Astoria Hotel & Residences — a 100-story, 1,049-foot skyscraper that will become Florida's first supertall — has climbed past its 35th floor at 300 Biscayne Boulevard, clearing more than one-third of its final height as of mid-2025.

Who is building the Waldorf Astoria tower and when will it be finished?

Developers PMG and Greybrook Realty Partners, working in partnership with Hilton, are pushing toward a topping-out date in late 2026, with the full building slated for delivery in January 2028.

  • Construction still has roughly 65 stories to climb before reaching its crown.
  • Development team has approximately two and a half years of active construction ahead.

What records will the Waldorf Astoria tower set?

When complete, the Waldorf Astoria tower will hold the title of tallest residential building south of New York City, and will become Florida's first structure to cross the supertall threshold of 984 feet (300 meters) — a category that currently has no other representatives in Florida.

  • At 1,049 feet, the tower crosses the formal threshold defining a supertall structure — buildings exceeding 984 feet, or 300 meters.
  • The project places Downtown Miami in the same conversation as Chicago, New York, and a handful of other American cities that have crossed that benchmark.

How are sales and design shaping the project's profile?

The building contains 360 residences across its upper floors, with more than 90 percent already sold — a remarkable absorption rate reflecting sustained demand for ultra-luxury product in the Downtown market even as broader real estate conditions have cooled elsewhere.

  • Tower features a sculpted, stacked form — a series of offset volumes giving the profile a distinctive, almost crystalline silhouette against the Biscayne Bay backdrop.
  • That shape poses engineering complexity, making each floor gained a notable construction achievement.
  • Tower is already visible from Brickell, the MacArthur Causeway, and across the bay from Miami Beach.
