Construction crews working on the Waldorf Astoria Hotel & Residences Miami have begun work on the tower's ninth and final glass cube, a milestone that puts the 100-story supertall on track to top out this winter at 300 Biscayne Boulevard in Downtown Miami. The tower reached level 85 as work began on the final segment, inching the project closer to its planned height of 1,049 feet.
According to Florida YIMBY, writer Oscar Nunez reported that the tower now has eight structurally legible glass cubes complete, with curtain wall installation extending through the seventh cube. New construction signage at the site tells passersby to look up, according to Joel Franco, and the same signage indicates the tower will top off in winter. Once finished, the building will surpass the 300-meter threshold required for supertall status and, according to the outlet's reporting, become the first supertall skyscraper in Florida.
A Fast Climb Since February
The pace of construction has been notable. The project reached its sixth cube after concrete work passed the 60th floor in February, meaning crews advanced roughly 25 additional levels in about six months before starting the ninth cube in late August. A Reddit user, u/ant0n61, shared construction images of the final cube on the site earlier in the week, capturing public interest in the tower's rapid rise.
The tower broke ground in 2022 and is anticipated to be completed in the second quarter of 2028. Behind the project are developers Property Markets Group and Greybrook Realty Partners, working alongside development partners Hilton, Mohari Hospitality, and S2 Development. Sieger Suarez Architects designed the building in collaboration with Carlos Ott, while BAMO is handling interior design, per the same outlet's reporting.
Record-Setting Foundation Work Set the Stage
The tower's foundation work made headlines of its own back in June 2024, when general contractor John Moriarty & Associates and Capform completed a continuous mat foundation pour lasting 31 hours. That single pour used approximately 12,400 cubic yards of concrete, required 1,240 truck deliveries, and involved 195 workers, according to Florida YIMBY's earlier coverage. Capform is delivering the turnkey concrete scope for the project, which secured $668 million in construction financing from Bank OZK and Related Fund Management in 2024.
The tower's final height of 1,049 feet is not an arbitrary target. Per a regulatory explainer, that figure represents the absolute maximum elevation permitted in Downtown Miami under Federal Aviation Administration rules meant to protect flight paths into Miami International Airport. That same ceiling now applies to Citadel's planned 62-story Brickell headquarters tower, which received FAA height approval for the identical 1,049 feet in July 2025, according to Miami Condo Investments. Once complete, the Waldorf Astoria tower will also become the tallest building in the Southern United States, surpassing Austin's 1,034-foot Waterline tower and Atlanta's 1,020-foot Bank of America Plaza, as reported by Newsweek.
Hotel Rooms Below, Luxury Condos Above
The finished building will contain both the Waldorf Astoria Miami hotel and the Waldorf Astoria Residences Miami, with 387 luxury branded private residences occupying floors 40 through 100 above a 205-room hotel in the lower cubes. Condominium offerings span from fully furnished 516-square-foot studios up to multi-bedroom suites and custom penthouses, according to Florida YIMBY's December 2025 reporting. The hotel base will feature the brand's signature Peacock Alley lounge, a resort pool deck, and a wellness spa, while condo owners get their own private residential lobby, lounge, and elevated pool deck.
Luxury demand for the project has already produced eye-popping numbers. A top-floor penthouse spanning more than 12,000 square feet in the tower's ninth cube sold for $50 million, a transaction PROFILEmiami described as a major benchmark for South Florida luxury real estate. The unit reportedly includes 360-degree views of Biscayne Bay and the Atlantic Ocean along with a private gym, theater, and wine room. Pre-construction sales launched back in May 2021, with developers projecting total residential sell-out revenue topping $1 billion, according to Miami Condo Investments.
Clearing a Troubled Site
The one-acre site at 300 Biscayne Boulevard has its own backstory. Developer Property Markets Group purchased the parcel for $80 million in November 2014 after the previous owners lost it following a fraud conviction that scuttled their proposed 93-story Empire World Towers, according to The Real Deal. The City of Miami Building Department later issued a phased vertical construction permit for the current project in January 2024, placing the structure's valuation at $426 million across 1.72 million gross square feet.
Once finished, the Waldorf Astoria will surpass Florida's current tallest completed building, the 85-story, 868-foot Panorama Tower in Miami's Brickell district, by 181 feet, per Wikipedia. Panorama Tower has held the statewide title since topping out in late 2017 and opening the following year. The Waldorf Astoria's rise is part of a broader building boom reshaping Downtown Miami and Brickell, a trend Hoodline has tracked with another supertall demolition nearby and rising towers along Biscayne Boulevard.
