Few addresses in Miami carry the kind of quiet gravity that 1809 Brickell Avenue now does. Rising along the Biscayne Bay waterfront in South Brickell, the St. Regis Residences is shaping up to be one of the most consequential luxury developments the city has produced in a generation. The tower is not just tall. It is deliberate, restrained, and built around the idea that a small number of people should have something genuinely extraordinary.
The project brings together a team that reads like a shortlist of the best in the business. What makes the priciest homes here worth examining is not just the numbers – it is how every layer of design, service, and location compounds into something that is genuinely hard to replicate elsewhere in Miami.
The Tower Itself: Scale, Scarcity, and Intention
Co-developed by Related Group and Integra Investments, with architecture by Robert A. M. Stern Architects and interiors by Rockwell Group, the St. Regis Residences, Miami will rise 50 stories and feature 152 ultra-luxury residences with floor plans ranging in size from 2,600 to 10,000 interior square feet. That last figure is worth pausing on. Ten thousand square feet in a Brickell condo tower is not a common thing.
Related Group and Integra Investments have broken ground on the tower, which features 152 bespoke residences including penthouses, sky villas, and two exclusive stand-alone garden villas. Over 65% of the homes at the 50-story ultra-luxury tower are already in contract, a figure that says as much about buyer confidence as it does about scarcity.
The $45 Million Penthouse: Miami’s Most Talked-About Listing
A $45 million duplex penthouse at the St. Regis Residences Miami, one of just two penthouses coming to market within the tower, is split across the 48th and 49th floor with a 50th-floor rooftop deck of the 50-story tower. That rooftop position alone separates it from practically everything else on the Brickell waterfront.
The unit includes a 2,842-square-foot rooftop deck that incorporates a sky-high swimming pool, spa, and a summer kitchen. Five bedrooms and seven bathrooms are spread throughout the home, and the primary suite occupies a wing of its own, complete with a sitting room, a midnight bar, and two bathrooms with split stone-top vanities, spacious natural stone showers, and a freestanding bathtub.
The $32 Million Garden Villa: A House Within a Tower
Priced at $32 million, the four-floor villa offers 7,617 square feet of indoor living space and an additional 2,726 square feet of stunning outdoor areas, including a rooftop terrace with a swimming pool overlooking Biscayne Bay. This is one of only two such villas in the entire building, which makes it genuinely rare even within a project defined by rarity.
Each of the home’s five bedrooms includes an en suite bath, and the primary bedroom, situated on the upper level, offers direct access to a 518-square-foot terrace, two oversized walk-in closets, and a midnight bar. The villa also includes a private garage, a windowed service suite, and an internal elevator – details that push it closer to a private estate than a traditional condominium.
The Legacy Collection: Seven Homes, Starting at $25.5 Million
A newly unveiled Legacy Collection at the St. Regis Residences, Miami introduces just seven upscale waterfront homes starting at $25.5 million, including sprawling penthouses and garden villas. The collection was launched in early 2026 and immediately drew attention for how it was positioned within the broader tower offering.
The lineup includes two stand-alone Villas, three multi-level Sky Villas, and two full-floor Penthouses, each designed as a distinct product rather than a repeated floor plan. Sizes range from approximately 7,600 to 9,900 square feet, placing these homes among the largest new-construction condo offerings in Miami. The Legacy Collection leans into larger, more customized residences that function closer to private homes than traditional condos, all paired with the St. Regis brand’s signature service model.
Price Per Square Foot: Where the Numbers Land
Brickell’s average price per square foot has nearly doubled over the past decade, from approximately $750 in 2015 to over $1,400 by 2024, driven by a combination of domestic relocation from high-tax states, Latin American and European capital seeking U.S. dollar-denominated assets, and a consistent undersupply of genuinely distinctive product at the top of the market.
St. Regis Residences Miami sits at the top of that market, at $1,770 to $2,200 per square foot, but the pricing is supported by factors that justify the premium: the brand, the architecture, the 152-unit exclusivity, the bayfront land, and the Rockwell Group finish levels. For context, listings tracked by brokers in early 2026 ranged from $4,600,000 to $12,404,000 for tower residences, with the most expensive homes pushing well above that ceiling.
The Architecture: RAMSA’s First Miami Residential Project
This property marks the first residential development in South Florida for Robert A. M. Stern Architects (RAMSA), who drew inspiration from the elegant aesthetic of golden-age ocean liners at sea, merged with the modern allure of skyscrapers. The reference is visible in the building’s composition: layered, proportioned, and deliberately different from the glass-box towers that dominate the Miami skyline.
The building marks a significant milestone for Robert A. M. Stern Architects, as it represents the firm’s first residential project in Miami and one of the final projects overseen by Robert A. M. Stern before his passing in 2025. RAMSA’s approach to modern classicism epitomizes timeless design at its most elegant, and its buildings have a track record of selling at a premium to the market.
Interior Finishes: What the Prices Actually Buy
Residences feature private elevators and entry foyers, 11-foot ceilings, floor-to-ceiling glass, and expansive private terraces. Interiors showcase custom Italian cabinetry, European marble flooring, integrated smart-home technology, Sub-Zero and Wolf appliance packages, and spa-inspired bathrooms with freestanding soaking tubs, oversized marble vanities, and Toto fixtures.
A gourmet kitchen in the penthouses offers bespoke Rockwell Group-designed Italian cabinetry with custom lighting and fully integrated Sub-Zero and Wolf appliance suites. The primary suites across the upper-tier residences are built around the concept of the midnight bar, a St. Regis signature that provides a private, stocked bar within the bedroom suite itself. It is a small detail that signals exactly what kind of living experience the project is after.
Amenities: 50,000 Square Feet of Shared Infrastructure
Residents have access to St. Regis’s signature butler services, as well as 50,000 square feet of indoor and outdoor amenities, including a professional-grade fitness center, Pilates and yoga studios, a full-size pickleball court, a private marina, a spa, a holistic wellness center, and an indoor lap pool.
On the 31st floor, residents will discover the Sky Lounge, an elegant social retreat featuring the St. Regis Cognac Room, St. Regis Tea Room, and signature lounge areas designed for relaxation and intimate gatherings. In true St. Regis fashion, there is also a St. Regis Tea Room and a resident-only fine dining restaurant helmed by chef Fabio Trabocchi, who owns Michelin-starred restaurants. Additional lifestyle features include a double-height grand lounge, wine vault, golf simulator, business center, media room, and pet spa.
Notable Buyers and Market Positioning
The building drew attention from high-profile buyers, including Formula 1 driver Sergio “Checo” Pérez, marking the tower’s first notable celebrity transaction. That kind of early buyer activity tends to shape the perception of a building before it even opens, and in Miami’s luxury market, perception matters considerably.
Related Group and Integra Investments secured a $527 million construction loan for the St. Regis Residences, the latest in a string of half-a-billion-dollar loans for top-tier projects across the city. Currently under construction, the St. Regis Residences, Miami is scheduled for completion in Q4 2027, bringing the legendary sophistication of St. Regis hospitality to the scenic Brickell waterfront.
Location: South Brickell’s Waterfront Advantage
South Brickell is distinct from Brickell’s urban core – quieter and more residential, with direct bayfront access that the denser blocks to the north simply don’t offer. The address at 1809 Brickell Avenue sits between the Coconut Grove waterfront to the south and the Brickell financial district to the north, offering walkable access to restaurants and offices while remaining removed from downtown congestion.
The property spans across three waterfront acres with breathtaking vistas of Biscayne Bay and swift connectivity to Downtown Miami, Brickell, and Coconut Grove. The secure, private setting offers residents peace and exclusivity while remaining minutes from Coconut Grove, Downtown Miami, and the Miami Design District. South Beach and Miami International Airport are less than 15 minutes away. For buyers whose lives span multiple cities, that kind of operational ease is rarely incidental to the purchase decision.
