The developers behind the St. Regis Residences at 1809 Brickell Avenue are advancing the 47-story tower as Miami's luxury condo market continues to draw attention.
According to latination.com, the St. Regis Residences project is spearheaded by Related Group and Integra Investments. The project is discussed alongside broader questions about yacht-space shortages in South Florida.
A Tower Already Drawing Record Money
A penthouse at St. Regis Residences entered contract for $47 million, a sale that ranked among the highest residential deals in the market that year, per the same account. That figure builds on a market already reshaped by ultra-luxury pricing — Hoodline previously reported on the $47 million deal, noting that mainland Miami's prior condo price record was set in March, when two penthouses at the Residences at Mandarin Oriental on Brickell Key each sold for $49.9 million.
Construction at the site was not without complications. St. Regis Residences construction experienced delays linked to the discovery of a Native American archaeological site, later confirmed as a 3,500-year-old Tequesta Indigenous settlement containing fire pits, pottery, stone tools, and human burial remains, according to Florida YIMBY. The site was later determined eligible for listing on the National Register of Historic Places, yet the City of Miami confirmed in March 2026 that it had no plans to designate the parcel as an official historic landmark, as reported by The Art Newspaper, which noted that Related Group had previously faced controversy over a separate 2,000-year-old Tequesta site at its nearby 444 Brickell Avenue development.
Why Public Waters Are Suddenly in Play
Florida requirements for docks or marinas on state-owned sovereign submerged lands include applicable approvals and environmental requirements, per the seed reporting. State rules add another layer: under Chapter 18-21 of the Florida Administrative Code, private developers building docks or marinas on state-owned sovereign submerged lands must obtain a lease from the Board of Trustees of the Internal Improvement Trust Fund, according to the Florida Department of Environmental Protection.
National boat registrations are part of the broader maritime context. The article also discusses maritime developments across the county, while the original report addresses regulatory requirements that can apply to such projects.
Competing Projects Reshape the Bay
The St. Regis proposal is far from the only megayacht project reshaping Biscayne Bay. Terra Group has submitted plans to construct a superyacht marina with 325 wet slips and a 500-boat dry stack facility at the former Miami Seaquarium site on Virginia Key, with about 90 slips able to accommodate yachts longer than 80 feet, according to The Real Deal. David Martin planned to invest between $75 million and $100 million in the project. Florida DEP regulators have since issued a six-page request for detailed plans on dredging, water quality, and coral protections tied to that project.
Miami voters will also weigh in directly this fall: a November 3 ballot measure asks whether to authorize a long-term municipal lease of 27.62 acres on Virginia Key, letting developer Virginia Key LLC carry out an $80 million privately funded renovation of the Rickenbacker and Marine Stadium marinas, per WLRN. The measure's placement on the ballot was reported by WLRN.
Even Miami's most famous yacht owners are chasing custom infrastructure. Billionaire Ken Griffin secured approval for a private Terminal Island marina designed for his 308-foot superyacht. The broader story includes related coverage.
What's Riding on Approval
The discussion concerns Miami's waterfront. The broader industry context in the cited NMMA material concerns national boat registrations.
Construction at St. Regis Residences continues, while Terra's Seaquarium project and the Virginia Key ballot question represent other waterfront developments playing out along Miami's waterfront.
