Waldorf Astoria Hotel and Residences Miami

The Waldorf Astoria Hotel & Residences Miami will be Florida’s first supertall when it tops out, and the tallest residential building south of New York City. The 100-story, 1,049-foot tower at 300 Biscayne Boulevard cleared the 60th floor in early 2026 and is on track to top out in late 2026, with final completion scheduled for January 2028.

Project Scope

The tower stacks 387 private condominium residences above 205 Waldorf Astoria hotel keys, separated vertically with dedicated lobbies, amenity floors and service cores. The exterior reads as nine offset glass cubes that step and rotate up the tower’s height, a massing strategy designed by Sieger Suarez Architects and Carlos Ott that breaks the supertall slab into discrete volumes and gives the upper residences private outdoor terraces where the cubes meet.

Property Markets Group is leading development alongside Greybrook Realty Partners, Mohari Hospitality, S2 Development and Hilton as the hotel operator. Plaza Construction is delivering the project under a design-bid-build model. The structural system uses a high-strength reinforced-concrete core with outrigger framing into the perimeter columns; the slab system is post-tensioned to keep floor-to-floor heights compatible with the cube geometry.

The build sits on a downtown Miami waterfront parcel at the south edge of Bayfront Park, with direct sight lines down Biscayne Bay. The hotel keys are on the lower floors, residential units above; the highest condos occupy the upper cubes near the 1,000-foot mark.

Why It Matters

The Waldorf Astoria is the first time Miami has gone above 1,000 feet, and the regulatory path to a supertall in the city has been more difficult than the buyer demand would suggest. The FAA’s protected airspace around Miami International Airport caps a wide swath of downtown construction, and 300 Biscayne sits inside one of the few corridors where a supertall envelope is even achievable. The project effectively reopens a height ceiling that has held in Miami for decades.

On the demand side, the build is also a barometer for ultra-luxury residential pricing in South Florida. Pre-sales have run well ahead of comparable Manhattan projects per square foot, which is the structural reason Sieger Suarez and Carlos Ott were given enough budget to push the cube concept rather than design a more conventional supertall slab. If the sellout holds through delivery, expect a second wave of supertall proposals along Brickell and the bayfront within the next 24 months.
