The St. Regis Residences, Miami is a 50-story branded tower under construction at 1809 Brickell Avenue on the Biscayne Bay waterfront in South Brickell. Co-developed by Related Group and Integra Investments with architecture by Robert A.M. Stern Architects and interiors by Rockwell Group, the St. Regis Brickell project broke ground in late 2024 and is targeting a 2027 delivery. The tower will hold 152 bespoke residences including penthouses, sky villas, and two stand-alone garden villas on the bayfront grounds. St. Regis Brickell floor plans run two- to seven-bedrooms with private elevators and entry foyers, 11-foot ceilings, floor-to-ceiling glass, and deep private terraces oriented to Biscayne Bay. The South Brickell address places the St. Regis Residences below the SE 15th Road waterfront, a quieter, lower-density stretch of Brickell Avenue closer to the Rickenbacker Causeway than to Brickell City Centre. The site holds direct Biscayne Bay frontage and a planned private marina, with Brickell City Centre, Mary Brickell Village, and the Brickell Metromover loop a short drive north. Key Biscayne is across the causeway, and Coconut Grove sits a few minutes south, giving St. Regis Brickell residents access to multiple waterfront enclaves from a single bayfront base. The St. Regis butler service is the centerpiece of the amenity program, delivering personalized service in every residence including on-premises house car, in-residence dining, packing and unpacking, and shoeshine. The St. Regis Residences Miami amenity package spans more than 50,000 square feet across indoor and outdoor levels: a professional-grade fitness center with pilates and yoga studios, a full-size pickleball court, an indoor lap pool, a resort-style pool deck with a poolside bar, a private marina, a holistic wellness center with a salt spa room, the brand's signature Tea Room and Cognac Room, a private restaurant, a beach club, a children's entertainment room, a teen video game lounge, and a business center cafe.
