Downtown Miami's skyline is about to get a new high point, and it will be impossible to miss. At 300 Biscayne Boulevard, the Waldorf Astoria Hotel & Residences Miami is rising as the first supertall in Florida — a stack of nine offset glass cubes that will top out around 1,049 feet, making it the tallest building south of New York. This is a deep-dive on what the building actually is, drawn from our building research, and on who it fits.
Florida's first supertall
"Supertall" is a defined term — a building over 300 meters, roughly 984 feet — and the Waldorf Astoria will be Florida's first to cross it, at a planned 1,049 feet and 100 stories. Designed by Sieger Suarez with Carlos Ott and developed by a PMG-led partnership, it is under construction with completion targeted for 2028. Height alone is a marketing hook, but here it also buys something concrete: views across Biscayne Bay and the Atlantic from a vantage no other Miami residence will match, because nothing else downtown will be this tall.
Nine cubes, and the engineering underneath
The building's signature is its form: nine offset glass cubes stacked and rotated up the tower rather than a single continuous shaft. It is a genuine architectural statement in a skyline full of glass rectangles, and it gives the residential floors setbacks and terraces a straight tower would not have. As with any distinctive form, the interesting question for a buyer is how the shape translates into the floor plans — where the cube junctions fall, which lines get the terraces — and that is exactly the kind of detail to study line by line before choosing a residence.
The residences above the hotel
The residences begin high up, on the 55th floor, above the Waldorf Astoria hotel that occupies the lower levels — a branded hotel-residence arrangement that puts five-star service at the residents' disposal. Our research lists the hallmarks: Peacock Alley, a signature spa, and à-la-carte residential services, across 360 residences ranging from studios to four-bedrooms with interiors by BAMO. The hotel-below, homes-above model is familiar in Miami's luxury tier, and the appeal is the same everywhere it appears: hotel service and amenities without running them yourself, in exchange for the dues that fund them.
What it costs, from our directory
Per our building research — directory figures, not live comps — residences here have been offered from roughly 1 million dollars to about 15 million dollars, averaging in the neighborhood of 1,550 dollars per square foot depending on line, floor and finish. That range reflects the breadth of the unit mix, from downtown studios to large high-floor homes with the trophy views. Current availability and pricing move as the building sells toward its 2028 delivery; our live market report at /market-stats carries the citywide picture, and the building's own listing page tracks what remains.
The deposit schedule, and buying at ninety percent sold
The Waldorf Astoria is a preconstruction purchase, and our research shows it roughly ninety percent sold ahead of delivery on a deposit schedule of ten percent at contract, ten at groundbreaking, ten at a structural milestone and the balance of seventy percent at closing. Two things follow from ninety-percent-sold. First, remaining inventory is thin and skews to whatever lines have not moved. Second, a nearly-sold-out preconstruction tower still carries the delivery-timeline risk that a finished building does not — 2028 is years out. The discipline is unchanged: understand the deposit structure, what each installment buys, and the delivery assumptions before committing.
Who the tower fits
The Waldorf Astoria fits the buyer who wants a trophy downtown address with hotel-branded service and the single best view in the market, and who is comfortable with preconstruction timing and the dues that five-star service requires. It fits pied-à-terre and international buyers who value a lock-and-leave home in a globally recognized brand. It fits less well if you want to move in now, or if downtown's dense urban energy is not your setting — the beaches and Brickell answer different questions. For the availability and pricing on a specific line, that is a building-level conversation we are glad to have.
