Buyer Beware: Aston Martin Residences Faces Two Lawsuits

The world's first Aston Martin-branded residential tower in Downtown Miami is now facing two separate lawsuits filed within ten weeks of each other. One alleges fraud. The other alleges construction defects. Here's what's actually happening.

Key Takeaways

• The condo association filed two lawsuits against the developer and contractors in February and April 2026.
• The first lawsuit alleges fraud, self-dealing, and the omission of amenities, including a marina and a helipad.
• The second lawsuit alleges construction defects including cracked balcony concrete, waterproofing failures, and seawall corrosion.

Aston Martin Residences at 300 Biscayne Boulevard Way in Downtown Miami is a 66-story, 391-unit tower that opened 99% presold in April 2024. According to The Real Deal, the condo association has now filed two lawsuits against the developer and construction team, raising questions about what buyers at this price point need to investigate before closing.

The building is one of the tallest all-residential towers on the East Coast at 817 feet. The triple penthouse was priced at approximately $59 million. The sellout reportedly exceeded $1 billion. Developer G&G Business Developments (led by Argentinian grocery magnate Germán Coto) partnered with Aston Martin for the branding.

What does the first lawsuit allege?

In February 2026, the 300 Biscayne Boulevard Way COA sued the developer for running what it called "an immense shell game." The lawsuit alleges fraud, self-dealing through contracts with vendors with close ties to the developer, and the failure to deliver promised amenities, including a marina, helipad, and beach club. The association is seeking more than $5 million.

According to The Real Deal, the self-dealing contracts were allegedly signed immediately before the developer turned over control of the association in March 2025. The new COA president, Michael Diaz Jr. (a condo owner who is also a Miami attorney), hired lawyers and forensic accountants to review the association's finances after taking control.

A spokesperson for Riverwalk East Developments (the LLC that developed the project) told The Real Deal: "We are concerned that ongoing litigation may not serve the best interests of residents. We remain confident that the legal process will lead to a fair outcome."

What does the second lawsuit allege?

On April 15, 2026, the COA filed a second lawsuit under Florida Statute 558, alleging construction defects. The defendants include an affiliate of G&G Business Developments, Coastal Construction (the general contractor), Revuelta Architecture International, DeSimone Consulting Engineering, Shamrock Engineering, Capform, and approximately a dozen subcontractors.

The defect allegations are based on a forensic engineering report by Epic Forensics & Engineering. According to Bisnow, the report identified cracked concrete on balconies, exposed post-tension tendons, waterproofing failures, seawall cracks and corrosion, elevator defects, fire system leaks and corrosion, pool and spa waterproofing failures, a drooping balcony, loose fire sprinkler joints, and water intrusion.

COA attorneys David Haber and Daniel Levin of Haber Law told The Real Deal the lawsuit serves as a "buyer beware" for condo purchasers. Haber added: "The system of giving TCOs is flawed. The system of inspections is flawed. Developers are building these things as fast as they can. Quality construction is less important than getting it sold."

Coastal Construction responded: "Reviewing the allegations for merit and will defend accordingly... Coastal prides itself on always working with developers and HOAs to swiftly resolve any issues."

What do construction defect lawsuits actually mean?

As Larry Mastropieri explained on the Discover South Florida Podcast: "When people hear construction defects, they immediately think the worst, but that is not usually the case. A lot of the time, it is balconies that need touch-up work, vents installed incorrectly, roof leaks, or other building issues that need to be corrected. It is not always a Surfside-type structural concern."

The defects listed in the Aston Martin lawsuit range from cosmetic issues to potentially more serious structural and waterproofing problems. These are allegations in an active lawsuit, and no liability has been found. The legal process will determine which claims have merit and what remediation is required.

Mastropieri added: "The lawsuit serves as a buyer-beware warning, and I think that is fair. If you are buying in a building delivered recently, you may not know there are defect discussions or potential litigation unless someone flags them for you. A lawsuit makes that issue visible."

Is this part of a broader pattern?

The turnover report (a standard engineering assessment conducted when a condo association takes control from the developer) is what exposed the defects at Aston Martin Residences. This same independent inspection process, strengthened by Florida law after the Surfside collapse, has exposed problems in other recently completed buildings across South Florida.

One Thousand Museum, a Zaha Hadid-designed tower half a mile from Aston Martin Residences, faces similar legal exposure. The COA filed a construction defects lawsuit in February 2025 and a second lawsuit in April 2026, alleging that the developer waived reserve funding because it "didn't have the money to pay."

The pattern suggests that post-Surfside structural reviews are surfacing issues that might have gone unnoticed in previous market cycles. For buyers, this means due diligence on recently delivered buildings should include reviewing association meeting minutes, reserve studies, and any pending or threatened litigation.

What does this mean for the branded residence model?

Aston Martin Residences is the world's first Aston Martin-branded residential building and a flagship of the growing global trend of luxury brand licensing to real estate developers. The legal issues here carry reputational weight beyond this tower alone.

As Propmodo reported: "Branding is not a substitute for execution... when it doesn't work, it becomes a liability that magnifies legal, financial, and reputational damage."

Branded residences are marketed as a step above typical luxury, tying lifestyle aspirations to the brand's identity. When the brand's promise collides with missing amenities and construction defect allegations, the gap between marketing and reality becomes a legal and financial issue for buyers.
