St. Regis Residences Sunny Isles: Developer, Architect and Oceanfront Design

St. Regis Residences Sunny Isles is planned as a pair of oceanfront condominium towers at 18801 Collins Avenue in Sunny Isles Beach, the barrier-island city north of Miami Beach where Collins Avenue runs along the Atlantic. The site is the starting point for everything else about the project, because the design team had to resolve two questions at once: how to place two tall residential buildings on a single beachfront parcel, and how to give both of them a real relationship with the ocean.

According to the developer's press page in an item dated November 1, 2025, the project occupies 4.7 acres and is made up of two curvilinear towers designed by Arquitectonica. Haute Residence describes the parcel as 435 linear feet of Atlantic beachfront and calls it one of the last significant oceanfront sites of this scale in the Sunny Isles corridor. For a buyer who cares about the water, that frontage is the fact to understand first, since it shapes tower placement, the beach club and the amenity decks.

Sunny Isles Beach has become known for branded and design-driven towers along the shoreline, and the project sits within that context. MILLION's Journal notes that the same developer team previously delivered The Ritz-Carlton Residences, Sunny Isles, and it points to the nearby Bentley Residences as evidence of the neighborhood's appetite for bold design. Reading the St. Regis against those neighbors is a useful way to see what the new project is trying to do differently.

The St. Regis Residences are being developed by a partnership between Fortune International Group and Château Group, as the project's official website and the developer's own materials state. Fortune International Group is a South Florida firm with a long list of Miami condominium projects, and MILLION's Journal credits the developer team's earlier Ritz-Carlton Residences in Sunny Isles as a benchmark for service-led living on this coastline. That earlier tower is relevant because it was also an oceanfront, hotel-branded residential building in the same city.

A point worth understanding is how the brand relates to the developer. The official project website states that the residences are not owned, developed or sold by Marriott International, Inc. or its affiliates. According to that disclosure, La Playa Beach Associates, LLC uses the St. Regis marks under a license from Marriott, and Marriott has not confirmed the accuracy of the statements made on the site. In practice, the developer builds and sells the homes, while the St. Regis name and service standards come through a license. Buyers should ask for the documents that explain how that service relationship is structured and for how long.

Another detail is the project's two-phase structure. A later item dated April 27, 2026 described the North Tower as a 62-story, 150-unit building and the second phase of the project. Unit counts and delivery dates for pre-construction towers can be revised, so it is sensible to confirm the current numbers for each tower directly with the developer's sales team.

Arquitectonica, the Miami-founded firm led by Bernardo Fort-Brescia, is the architect of record for the towers. Haute Residence reports that the firm's portfolio spans 59 countries and that it designed the project as a pair of soaring ellipses. The choice of a curved plan, rather than a rectangular slab, is the central design decision, and the architect ties it directly to the place.

Fortune International Group's project page carries Fort-Brescia's own explanation: "The sun defines Miami. The Sunny Isles name is not accidental. The Earth's elliptical path is depicted in the towers' shapes. The monumental ever-changing curvature creates a form identifiable from afar against the open skies." Haute Residence relates the shape to Earth's orbital path around the sun. Whether or not a buyer finds the astronomical reference persuasive, the practical result is a silhouette that reads as sculptural from the beach and from a distance.

MILLION's Journal frames the architecture as sculptural rather than graphic, and says the choice of Arquitectonica fits the contemporary vertical profile of Sunny Isles Beach. That is an editorial judgment, not a measurement, but it points to a real distinction. Curved towers tend to present changing faces to the ocean and the sky through the day, and they avoid a flat wall of glass facing the shoreline. Prospective buyers should look at the floor plans and orientation for the specific residences they are considering rather than assume every line has the same exposure.

A beachfront tower succeeds or fails at the point where the building meets the sand. The official project website describes the development as a private residential resort, with wellness, fitness, dining and entertainment amenities spanning more than 70,000 square feet. It also says the residences are designed to evoke harmony with nature, including the ocean breeze, the soft white sand and the sound of the surf.

The amenity program is where that intent becomes concrete. MILLION's Journal highlights a beachfront club and what it calls a dramatic infinity-edge pool deck as part of the resort offering. The developer's press page, in an item dated April 27, 2026, reported plans for a 10,000-square-foot, full-floor spa on the fifth floor, designed by Patricia Anastassiadis. Raising the wellness program to a dedicated floor suggests the design team is treating the podium as a place to enjoy the coastal setting, not only as a base for the towers.

Landscape matters too on a site like this. Haute Residence names EDSA as landscape architect, citing the firm's work across resort, luxury residential and mixed-use projects worldwide. The material from the developer does not detail dune treatment, shoreline protection or elevation strategy, and those physical questions are best put to the developer directly. Buyers on any Atlantic oceanfront parcel are right to ask for the specifics of how the building and grounds are designed to handle the coastal environment.

Interiors are by Patricia Anastassiadis of São Paulo, who, according to Haute Residence, has a portfolio that includes Four Seasons, The Ritz-Carlton and Fairmont properties. For this project she drew directly on private yacht design, introducing a curvilinear language, couture-grade craftsmanship and organic materials throughout the common areas and residences. Haute Residence summarizes the result as simultaneously cosmopolitan and coastal, refined without rigidity.

The yacht reference is a sensible fit for a waterfront address and echoes the curved geometry of the towers. MILLION's Journal describes the interiors as prioritizing warmth and craftsmanship over ostentation, and its commentary on the project's first tower notes that composed, globally fluent interiors are a better approach than a themed or overly literal coastal palette. That restraint is a design position, and it gives buyers a clear basis for judging the finished spaces when sample residences or mockups become available.

Interior credits can differ between materials, so it is worth confirming who designs which spaces. The developer's press page attributes the spa design to Anastassiadis, and the project website and Haute Residence name her for the interiors. Ask the sales team for a current list of design credits covering the residences, the amenity floors and the landscape.

The St. Regis brand is central to the daily experience the project describes. The official website and MILLION's Journal both highlight the brand's butler service, and the developer's press page describes the amenity program as combining wellness, dining and signature St. Regis butler services. The developer's press page, in an item dated November 1, 2025, describes estate-like residences with panoramic views, and the project is intended as residences only, per Fortune International Group's materials.

Because this is pre-construction, details can change, and published sales materials do not always agree with one another. Sizes, bedroom counts and starting prices vary across public listings, and the figures that matter are the ones in the developer's current price list and offering documents. For price, the developer's press page, in an item dated December 2, 2025, said remaining residences started at $5 million; ask whether that is still current and which stacks and floors it covers.

For buyers focused on the water, a short list of questions can be useful. Which residences have direct ocean exposure and which look along the coast? How are the beach club, pool deck and spa placed relative to the sand? What is the timing for each tower, and how does the service program operate before and after delivery? Denis Smykalov and the team at Wolsen Waterfront can help organize those questions for oceanfront buyers comparing new developments in Sunny Isles Beach.
