Downtown and Worldcenter · Miami

Aston Martin Residences

At the mouth of the Miami River, the water is not the view. It is the property line. The developer publishes this as the only tower downtown with its own deep-water marina attached.

The water is the property line

Most Miami towers sell you a view of the bay. This one sells you the edge of it. Aston Martin Residences occupies the spit of land where the Miami River empties into Biscayne Bay, which means water on more than one side and an outlook that runs east past Brickell Key to the Atlantic, south over Brickell, and west up a working river that never quite goes quiet.

The developer, G&G Business Developments, publishes the site's defining feature as a deep-water marina built into the property — berthing described as capable of taking superyachts, at the river mouth, with the Miami Riverwalk running along the tower's southern edge. G&G also publishes a helipad on the roof. Those two claims are the developer's own, and they are the reason this address is not interchangeable with anything else downtown. Nowhere else in the Central Business District can you walk from a lobby to your own vessel.

The form follows from the site. Bodas Miani Anger, working with Revuelta Architecture International, drew a tapering sail that narrows as it rises to 817 feet across 66 storeys — a shape that reads differently from the bridge, from Brickell, and from the water itself. Aston Martin describes the completed building as the tallest all-residential tower south of New York.

The engineering matched the ambition. The 2019 foundation pour was reported at the time as the largest single concrete pour undertaken in the Miami region. The tower topped out on 1 December 2021 and opened in April 2024.

What the roll says, and what the brochure says

The Miami-Dade County Property Appraiser records this building as 300 BISCAYNE BLVD WAY CONDO, year built 2024. On the completion date, county and developer agree cleanly — the roll's 2024 lines up with G&G's published April 2024 opening. That is rarer than it sounds.

On the unit count they do not agree. The roll carries 392 residential folios. The developer publishes 391 residences. It is a difference of one, and it is the sort of gap that usually resolves into a staff unit, a manager's residence, a guest suite or a folio split that never made it into the sales collateral. We give both numbers because we would rather you knew the record than read a rounded figure.

Worth holding onto if you are underwriting: the roll is the operative document for taxes, for the declaration and for anything a lender asks about. The brochure is the operative document for what the building was designed to be. Both are true. They are answering different questions.

Four floors in the sky, and what they actually feel like

The amenity programme is not scattered through the podium. It is lifted and stacked — 42,275 published square feet across levels 52 to 55, five hundred feet in the air, which changes what using them feels like. You do not swim next to a parking ramp here.

Level 55 is the top of it: a heated infinity pool with spa tubs and cabanas, a pool bar, a grand living room and a chef's kitchen for when you want to hand off dinner. Level 54 holds two private cinemas and a golf simulator, and the fitness centre begins here, running down through 53 as a two-storey volume rather than a room with a mirror. Level 53 adds the spa proper — sauna, steam, a meditation room — plus a beauty salon and barbershop, and the art gallery and art lobby.

Level 52 is the floor that gets used on a Tuesday: kids playroom, teen centre, game rooms, business centre and conference rooms. It is a sensible piece of planning, keeping the noisy end of the programme one floor below the quiet end.

Ten destination-dispatch elevators move the building, which matters when your pool is on 55 and your car is in the podium. Valet runs 24 hours, parking is covered, and EV charging is installed.

The residences

The tower is banded, and the bands are named. Levels 3 to 14 are the River Residences, sitting low over the water and the Riverwalk. Levels 15 to 45 are the Panoramic Residences. Levels 46 to 51 are the Sky Residences, immediately below the amenity stack. Penthouses occupy 56 to 62, and a triple penthouse crowns 63 to 65.

Floor plans run from 698-square-foot studios through one- to five-bedroom layouts, with the developer publishing a top end past 18,000 square feet in the largest penthouse configurations. Ceilings are 10 feet in the residences and 12 feet in the penthouses, and every plan is glazed floor to ceiling with sliding doors onto balconies finished in porcelain rather than painted concrete.

Interiors are white marble through the living areas, kitchens and bathrooms, with custom Bulthaup cabinetry and Gaggenau appliances, quartz and marble counters, and Duravit fixtures. Buyers were offered three bespoke schemes developed with Aston Martin's designers — the marque's own language rather than an interpretation of it. Reichman has described that language as built on the honesty of materials, and the detailing bears it out down to the door hardware.

Seven penthouses were released in total. The triple penthouse at the top was published as a 27,000-square-foot residence delivered with an Aston Martin Vulcan track car included.

The neighbourhood, on foot and by car

Downtown Miami runs from the river north to the I-395 flyover and from Biscayne Bay west to I-95, with the Central Business District at the southern end — which is where this tower sits, at the very bottom of it, on the river.

Zuma is essentially next door at 270 Biscayne Boulevard Way. Il Gabbiano is at 335 South Biscayne. The Miami River's north bank is a restaurant row of its own within a few minutes — Seaspice at 422 NW North River Drive, Kiki on the River at 450, Garcia's Seafood Grille at 398. North on foot, Bayfront Park opens 32 acres redesigned by Isamu Noguchi at 301 Biscayne, with an amphitheatre, a rock garden, a dog park and a fountain of more than 800 synchronised jets; Bayside Marketplace at 401 Biscayne carries roughly 100 waterfront shops and restaurants alongside Miamarina, which holds 125 wet slips for vessels between 55 and 230 feet with fuel, pump-out and customs clearing.

Groceries mean a Whole Foods in the Central Business District, or the Publix at Brickell City Centre one Metromover stop south. The Metromover is free, runs 21 stations over 4.4 miles from 5 a.m. to midnight, and interchanges with Metrorail at Government Center. Brightline's MiamiCentral at 600 NW 1st Avenue runs to Fort Lauderdale, West Palm Beach and Orlando. Further afield but still walking distance: Kaseya Center at 601 Biscayne, the Freedom Tower at 600 Biscayne, and Miami Worldcenter's 300,000 square feet of street-level retail around World Square.

By car, Miami International is about 7 miles west, typically 15 to 25 minutes via SR-836. Fort Lauderdale-Hollywood is about 28 miles north, 35 to 50 minutes on I-95. South Beach is across the MacArthur Causeway and the Design District is roughly 10 minutes north on Biscayne Boulevard.

Who it suits

Anyone whose life includes a boat. That is the honest headline. The published marina at the river mouth is the single hardest amenity in this market to replicate, and if berthing a vessel a lift ride from your kitchen changes how you use a home, nothing else downtown competes on the same terms.

It suits the collector, and not only in the obvious branded sense — covered valet parking with EV charging, a design partnership with a car company, and a building that was conceived around the idea that how you arrive is part of the architecture.

It suits the second-home owner who wants to close the door and leave. Full-time valet, 24-hour attendance, a self-contained amenity stack on four floors and a brand-new 2024 building mean very little of your attention is required between visits.

And it suits entertaining. A chef's kitchen and grand living room on 55, a pool bar, two cinemas, a sky lounge and conference rooms give you somewhere to put fourteen people that is not your dining table — which is exactly what the larger floor plans and penthouse levels were drawn for.
