Developers behind The St. Regis Residences, Sunny Isles Beach have secured $463 million in financing to push forward the oceanfront condominium project under construction at 18801 Collins Avenue in Sunny Isles Beach. The new loan, provided by Madison Realty Capital, refinances existing debt from Bank OZK and adds capital for continued work on the development’s 62-story South Tower.
The financing arrives as vertical construction is underway following the completion of foundation work on the South Tower this summer. The tower is now more than 80 percent sold and is planned for 170 condominium residences, underscoring continued demand for ultra-luxury waterfront homes in one of Miami-Dade County’s most active high-end residential markets.
The transaction was arranged by Berkadia Miami and comes as the project advances through a two-tower program that will eventually total 320 residences across both phases. The development team also recently relocated the sales gallery across Collins Avenue as preparations move ahead for the project’s second tower.

Financing supports the next stage of construction
The $463 million financing package is designed to support the next phase of work at the South Tower while also refinancing prior debt tied to the project. The loan was arranged as the tower moves into its vertical construction phase, following completion of foundation work earlier this year.
For a project of this scale, securing construction capital after reaching the vertical stage can be a critical milestone. It allows the developers to continue building while maintaining momentum in sales, coordination with contractors, and planning for the broader two-phase delivery schedule.
The South Tower is the first phase of the St. Regis-branded project in Sunny Isles Beach. Its financing also reflects the level of lender confidence in the project’s sponsors and its location on one of South Florida’s most valuable oceanfront corridors.
What is being built at 18801 Collins Avenue
The St. Regis Residences, Sunny Isles Beach is planned as a two-tower condominium development on a 4.7-acre oceanfront site with approximately 435 linear feet of Atlantic Ocean frontage. The project calls for two 62-story towers rising to roughly 750 feet along the beachside property.
The South Tower, now under construction, will include 170 residences. A future North Tower is planned with 150 residences, bringing the full development program to 320 units. The North Tower has already secured separate financing, with a $113.75 million development loan from City National Bank of Florida earlier this year to support pre-development activity for the second phase.
With both towers, the project is positioned as one of the larger luxury condominium ventures underway in Sunny Isles Beach, a submarket that has long attracted high-rise residential development because of its beach frontage, limited land supply, and proximity to Bal Harbour, Miami Beach, and Aventura.
Design team and project partners
The development team includes Fortune International Group and Château Group, two South Florida firms that have been active in the region’s luxury residential market. The project’s design architect is Arquitectonica, with Anastassiadis handling interior design, EDSA serving as landscape architect, and Coastal Construction acting as general contractor.
The financing was arranged by Berkadia Miami, with a team led by Managing Director Scott Wadler and Director Michael Basinski. Additional Berkadia participants included Senior Managing Director Mitch Sinberg, Managing Directors Matt Robbins and Brad Williamson, and Senior Analyst Matthew Monahemi.
The lenders and advisers involved in the transaction point to the combination of oceanfront location, brand affiliation, and project scale as key factors behind the financing structure. The project’s service model is also designed to blend residential living with hospitality-style offerings, a format that continues to appear in the highest end of South Florida’s condo market.
Amenities and residential programming
More than 70,000 square feet of amenity space is planned across the property. The development is expected to include two restaurants, a full-service spa, swimming pools, fitness and wellness areas, and additional hospitality and resident programming.
While full residential details have not been publicly disclosed in the provided material, the amenity package suggests the project is being positioned for buyers seeking a branded, resort-style ownership experience rather than a conventional condominium program. In Sunny Isles Beach especially, projects of this type often compete on service, privacy, and direct ocean access as much as on unit design and tower height.
The developers have said the project has continued to evolve as the overall concept has taken shape. That includes adding hospitality components and dining concepts intended to become part of the property’s long-term identity.
Sales progress and project timeline
The South Tower is now more than 80 percent sold, a notable milestone for a project still under construction. The current schedule lists 2028 for completion of the first phase and 2029 for the second phase.
As the North Tower moves closer to its next stage, the developers have relocated the sales gallery across Collins Avenue to 18590 Collins Avenue. That shift signals continued preparation for future marketing and sales activity tied to the second tower.
The separate financing already secured for the North Tower earlier this year indicates that the project is being advanced in phases rather than as a single all-at-once buildout. That approach can help manage construction timing, capital deployment, and sales absorption across a large oceanfront site.
Why the project matters in Sunny Isles Beach
Sunny Isles Beach has remained one of the most closely watched luxury condominium submarkets in South Florida because available oceanfront land is limited and new supply tends to be concentrated in large, high-profile towers. The St. Regis Residences, Sunny Isles Beach adds another major branded project to that corridor, where developers continue to pursue buyers interested in new construction, hotel-level services, and direct beach access.
The size of the financing package also underscores the scale of the development and the level of capital still flowing into prime coastal residential projects in Miami-Dade County. For lenders, sponsors, and buyers alike, the deal reflects continuing interest in top-tier oceanfront product that can support high price points and long delivery timelines.
At the neighborhood level, the project adds to the ongoing transformation of Collins Avenue in Sunny Isles Beach, where many of the area’s newest luxury towers are reshaping the skyline and the residential market. The St. Regis project stands out not only for its branding but also for its two-phase structure, substantial ocean frontage, and the amount of amenity space planned across the site.
