Aston Martin Residences, by the numbers

Aston Martin Residences is the clearest example in Miami of a design-branded building, and the distinction is worth more than the badge. The brand was applied once, at delivery, and cannot be withdrawn. There is no operator contract to expire, no management agreement to renegotiate, no third party who can walk away and take the name with them. Whatever happens to the company, the building is unchanged. Very few branded residences can say that.

The specification conflict, published rather than smoothed over
Two credible primary sources give different numbers for this building, and most coverage silently picks one.



| Aston Martin (30 Apr 2024) | Coastal Construction (GC) | |
|---|---|---|
| Storeys | 66 | 70 |
| Residences | 391 | 393 |
| Architect | Rodolfo Miani, Bodas Mian Anger | Revuelta Architects International |
The likely explanation, stated as a likelihood rather than a fact: the storey difference is almost certainly residential floors versus total floors including amenity and mechanical levels — a routine discrepancy in Miami towers. The unit-count difference is consistent with a late reconfiguration of one or two residences, which happens frequently in the final year of construction. On the architect, both names may be correct: Miami projects commonly carry a design architect and a separate architect of record, and the two sources may simply be naming different roles.
None of that is confirmed, so none of it is asserted. If the exact count matters to your purchase — and for a resale valuation built on price per unit or per floor, it does — pull the recorded declaration of condominium rather than relying on any published figure, including this one.
Why “design-branded” is the whole story here
Branded residences are usually sold on a name and priced on an assumption. The assumption is that the name is permanent. Frequently it is not.



A service-brand is a live operating relationship. A hotel or hospitality operator runs the building under a management contract with a term. It can be renegotiated. It can end. The staffing, the service standard and the name over the door are all contingent on a third party continuing to show up — and the premium you paid assumed they would.
A design-brand was applied once, at delivery. The architecture, the interiors, the specification and the identity are fixed. They cannot be withdrawn. Aston Martin Residences is design-branded in the strictest sense: this was the marque’s first real estate project, the design language is built into the structure, and there is no ongoing operating agreement whose expiry could change what you own.
Both models can justify a premium. They carry completely different long-run dependency, and the market frequently prices them as though they were identical. That is the single most useful thing to understand before paying a brand premium anywhere in Miami.
What completion in 2024 means in the 2026 market
This building is finished and was 99% sold before it opened. That makes it a resale market now, not a launch, and it changes which questions matter.



The milestone advantage, and it is a real one
Florida Statute 553.899 requires a milestone structural inspection of any condominium building three habitable stories or more by 31 December of the year it reaches 30 years of age, then every ten years — with a local enforcement agency able to require the first at 25 years where conditions such as proximity to salt water warrant it.
Aston Martin Residences opened in 2024. Its first milestone inspection therefore falls around 2054, or roughly 2049 if the 25-year discretion is applied. That is decades of no milestone exposure, in a market where a great many desirable buildings are at or past their first inspection and carrying the assessment risk that follows. For a buyer weighing this against an older waterfront address, that gap is worth real money and is almost never quantified. ⚠️ But statutory milestone timing is not the same thing as an absence of structural questions, and on this building it is important not to confuse the two. The condominium association filed a construction-defect action against the developer in March 2026, described below.
The financing questions that still apply
Being new does not exempt a building from the 2026 lending regime. Since 3 August 2026, Fannie Mae has retired the Limited Review process for established projects under Lender Letter LL-2026-03; a Full Review now applies at every down-payment level unless a project has ten or fewer units. Since 1 July 2026, a master policy deductible above $50,000 per unit breaks eligibility. From 4 January 2027, minimum reserves rise to 15% of annual budgeted assessment income.
A four-year-old tower should clear all of this comfortably — but “should” is not “does”. Ask for the master policy deductible and the current reserve allocation before you assume it. With 48.5% of Miami-Dade condominium sales closing in cash, the other half of your future buyer pool depends on the answer.
🔴 The two lawsuits between the owners and the developer
This is the part of the building’s record a buyer most needs and is least likely to be shown. The condominium association — the owners, collectively, after turnover from the developer — has filed two separate actions in 2026 against the developer, Riverwalk East Development LLC, and related parties.



January 2026 — the amenities and self-dealing action. It alleges that promised amenities including a private marina, a helipad and concierge services were not delivered, together with allegations of self-dealing and financial mismanagement.
March 2026 — the construction-defect action. As reported, the claims include crumbling concrete balconies with exposed reinforcement steel, unsealed concrete and shattered glass on balconies, corrosion and rust from water intrusion, a drooping balcony, loose fire-sprinkler joints causing leaks, and corrosion and cracking in the seawall. Reporting describes a turnover inspection by an outside forensic engineering firm identifying concrete cracking, water intrusion and issues with the building’s post-tension system. The association is reported to be seeking damages and an order compelling repairs.
The developer denies the allegations and is contesting both actions. A spokesperson told CBS Miami: “The association has made allegations that we believe are unfounded and appear to divert attention from unresolved obligations on their part.” The same statement expressed the developer’s commitment to quality construction and confidence that the legal process would reach a fair outcome.
Everything above is an allegation in pending litigation, and nothing has been decided by a court. I am not telling you the defects exist, that the claims will succeed, or that anyone acted unlawfully. I am telling you the actions were filed by the owners themselves and that they are live — which is a material fact about a building, and one a page recommending this tower should not omit.
What to do about it. Have your attorney pull both complaints from the Miami-Dade docket and read them. Then request from the association: the current reserve study, the litigation disclosure on the estoppel certificate, any special-assessment history or proposal, the turnover inspection report, and the master insurance policy with its deductible. A pending construction-defect action can affect financing availability, insurance pricing and future assessments — all three of which you carry as an owner regardless of how the case ends.
What the county record shows about the marina
The public record does not resolve the marina dispute, but it documents something specific and checkable. The marina exists in the declaration as its own commercial condominium unit: folio 01-4206-071-3980, UNIT CU-M, classified by the county as DOCK — COMMERCIAL CONDO, 982 square feet, carrying a 0.1140% share of the common elements. It sold on 23 September 2024 for $1,080,000 on a qualified deed, and the owner of record is a private limited-liability company. The building’s three retail units conveyed the same day to a different private company.
So the marina was created as a separate saleable commercial unit inside the condominium and conveyed to a private owner, rather than held as a common element belonging to all the residences. Whether that is what buyers were promised is exactly what the litigation is about, and this page does not take a position on it. I could not establish from the public record whether the purchasing company is connected to the developer, and I am not implying that it is. If you are buying here partly for marina access, this is the fact to put in front of your attorney.
What is actually at Aston Martin Residences?
The amenity programme is 42,275 square feet of “Sky Amenities” across four levels, floors 52 to 55 — a two-floor fitness centre, art gallery, two cinemas, a virtual golf simulator, business centre and conference room, children’s playroom, spa, beauty salon, barber shop, infinity pool, sky bar and lounge, chef’s kitchen, ballroom and private dining rooms.


















The feature that genuinely distinguishes the building is the superyacht marina with direct water access — a rare thing for a Downtown tower, and the reason this address competes with waterfront addresses rather than with other Downtown product. If a slip is part of why you are buying, confirm the specific slip, its dimensions, its ownership structure and its transferability in writing, because marina rights vary enormously and are not always what a listing implies. ⚠️ On this building that is not a generic caution. The county records the marina as a separately owned commercial condominium unit that sold for $1,080,000 in September 2024, and the association’s pending action alleges the promised marina was never delivered to residents. Both are set out below.
⚠️ A note on this page’s URL. It sits under /new-construction/ for historical reasons. The building was completed in April 2024 and is not new construction. The path is retained deliberately — it holds inbound links and search history — but the building’s status is complete.
Aston Martin Residences — common questions
Is Aston Martin Residences finished?
Yes. It officially opened on 30 April 2024 at 300 Biscayne Boulevard Way in Downtown Miami, developed by G&G Business Developments, with 99% of the residences sold before completion. It is a resale market now, not a launch.
How many units and floors does it have?
Sources conflict, and this page publishes both rather than picking one. Aston Martin’s own completion announcement says 66 storeys and 391 residences. Coastal Construction, the general contractor, records 70 storeys, 393 residences and a height of 821 feet. The storey gap is most likely residential floors versus total floors including amenity and mechanical levels; the unit gap is consistent with a late reconfiguration. Neither explanation is confirmed. If the exact count matters to your valuation, pull the recorded declaration of condominium.
Who designed it?
Also disputed between sources. Aston Martin credits Rodolfo Miani of Bodas Mian Anger; Coastal Construction credits Revuelta Architects International. Both may be correct, because Miami projects commonly carry a design architect and a separate architect of record, and the two sources may be naming different roles.
What does design-branded mean, and why does it matter here?
A design-brand was applied once at delivery: the architecture, interiors and specification are fixed and cannot be withdrawn. A service-brand is a live operating relationship, with an operator running the building under a contract that has a term and can end. Aston Martin Residences is design-branded in the strictest sense, as the marque’s first real estate project, with no ongoing operating agreement whose expiry could change what you own. Both models can justify a premium; they carry very different long-run dependency and are frequently priced as though identical.
When is its first milestone inspection?
Around 2054. Florida Statute 553.899 requires a milestone structural inspection by 31 December of the year a building reaches 30 years of age, then every ten years, with a local agency able to require the first at 25 years near salt water, which would bring it to roughly 2049. The building opened in 2024, so it carries decades of no milestone exposure. Against older waterfront buildings at or past their first inspection, that is a genuine and rarely quantified advantage.
Do the 2026 condo financing rules affect it?
They apply, though a four-year-old tower should clear them comfortably. Since 3 August 2026 a Full Review applies at every down-payment level under Fannie Mae Lender Letter LL-2026-03; since 1 July 2026 a master policy deductible above $50,000 per unit breaks eligibility; and from 4 January 2027 minimum reserves rise to 15% of annual budgeted assessment income. Ask for the deductible and reserve allocation rather than assuming, because 48.5% of Miami-Dade condo sales close in cash and half your future buyer pool depends on the answer.
What about the marina?
The superyacht marina with direct water access is the feature that makes this address compete with waterfront buildings rather than with other Downtown product. Marina rights vary enormously, so confirm the specific slip, its dimensions, its ownership structure and its transferability in writing before assuming anything a listing implies.
Are there lawsuits at Aston Martin Residences?
🔴 Yes. The condominium association filed two actions against the developer in January and March 2026 — one alleging that promised amenities including a private marina, a helipad and concierge services were not delivered, together with self-dealing and financial mismanagement; the other alleging construction defects including cracked balcony concrete, exposed reinforcement steel, water intrusion, seawall corrosion and problems with the post-tension system. These are allegations in pending litigation. The developer says they are unfounded and is contesting them, and no court has decided either case. Have your attorney pull both complaints and read them before you sign.
Who owns the marina at Aston Martin Residences?
The county records the marina as its own commercial condominium unit — UNIT CU-M, classified as a commercial dock, 982 square feet — which sold on 23 September 2024 for $1,080,000 to a private company. So it is separately owned rather than a common element belonging to all the residences. ⚠️ Whether that matches what buyers were promised is the subject of the association’s pending action, and this page takes no position on it. Confirm any slip rights in writing.
