A stack of glass cubes is rising in the heart of downtown Miami.
Builders of Waldorf Astoria Hotel & Residences Miami are making major strides in the creation of this unique skyscraper, according to a representative of the development partnership with PMG.
In an email to Miami Today this week, PMG offered details of the status of the sweeping mixed-use residential tower rising at 300 Biscayne Blvd.
The 1,049-foot tower will feature nine spiraling, offset glass cubes that distinguish the property’s architecture from anything else on the East Coast, say the developers.
The high-profile site is at the northwest corner of Biscayne Boulevard and Northeast Third Street, directly across from Bayfront Park.
Asked about progress or milestones in the project, PMG reports that by March the development team had successfully poured 19 floors and rapid progress continues with an average of pouring one floor every 10 days.
“The team has just begun pouring the pool level, which will be followed by the amenity level. They are also working on installing the glass facade in Cube One,” said the company email.
Official groundbreaking was in October 2022.

PMG said the historic foundation pour was led by John Moriarty & Associates alongside CAPFORM.
A major accomplishment was scored in June 2024 that helped kick off vertical construction in a major way.
National developer PMG, along with partners Canadian private equity firm Greybrook, global investment company Mohari Hospitality, S2 Development, and global hospitality company Hilton announced they had secured $668 million for the project.
PMG said it was the largest construction loan for a residential condominium development in Florida’s history, provided by Bank OZK and Related Fund Management.
The development team is currently working through Cube 3 out of 9 cubes.
The glass tower will be home to 387 private residences, in addition to 205 guestrooms and suites within the luxury hotel, which will be in the first three cubes of the tower along with the hotel’s signature spaces and private amenities.
The tower’s concept design is led by Sieger Suarez Architects, in collaboration with architect Carlos Ott and interior design firm BAMO.
PMG and Greybrook say that hotel guests and residents will have access to the Waldorf Astoria brand’s Peacock Alley; a specialty restaurant; indoor/outdoor pre-function and function event spaces; meetings and boardrooms; a resort-style pool deck with private cabanas; and a holistic wellness spa and fitness center.
Private residential amenities will include an owners-only lobby and lounge; hospitality suite for chef’s tastings and intimate soirees; billiard room; kid’s club; and elevated pool deck.
Each residence is to include smart-home technology with custom mobile app access to concierge services.
The private roof deck is to feature a pool, swim-up tiki bar, outdoor gym and courts for basketball, racquetball and pickleball.
Completion is targeted for 2028.
