St. Regis Residences Sunny Isles: Oceanfront New Build vs. Sunny Isles Beach Resale Condos

St. Regis Residences Sunny Isles is an oceanfront condominium development at 18801 Collins Avenue in Sunny Isles Beach, directly on the Atlantic Ocean. According to the official project website, it is being built by Fortune International Group and Chateau Group and designed by Arquitectonica. The website describes it as a private residential resort in two towers, and states that the project is under construction and now selling the North Tower Collection. The same site notes that the project is not owned, developed or sold by Marriott International; the developer, La Playa Beach Associates, LLC, uses the St. Regis marks under license.

That framing shapes the comparison with older buildings. Sunny Isles Beach is a narrow barrier-island city, with the ocean on one side and the Intracoastal Waterway on the other, and most of its oceanfront towers were delivered in earlier building cycles. A buyer weighing St. Regis Residences Sunny Isles against a resale tower is not choosing between two versions of the same product. The choice is between a building still being completed and one that already has years of operating history.

This article sets the two side by side on four points: building age, amenities, layouts and the water itself. It does not forecast how any building will perform. Pricing, delivery schedules and availability for a project under construction change, so those are best confirmed directly with the developer.

The most basic difference is age. The established oceanfront towers of Sunny Isles Beach have been occupied long enough to show how they are run. Buyers can read recent association records, see how common areas have been maintained, and walk the building as it actually operates. Legacy luxury towers in the city are typically described as established oceanfront buildings with a long operating history, larger floor plans and full-time staff, which suits buyers who value proven service over the newest design language.

St. Regis Residences Sunny Isles offers something different. The official website lists the project as under construction. Public project materials describe a South Tower that began site work first and a North Tower that follows on a later schedule, and the website says the North Tower Collection is the one now being sold. A buyer here is reasoning from plans, renderings and a developer's track record, not from a lived-in building. Delivery dates for each tower, deposit schedules and the terms of the purchase contract should be requested from the developer in writing.

There is a practical effect on due diligence. With a resale condo, the questions concern the past: reserve planning, past repairs, rules and the condition of the unit. With a pre-completion purchase, the questions concern the future: when each tower is expected to be finished, which residence lines remain, and what the governing documents will say once an association takes over. Neither path is inherently safer. They call for different questions.

The official project website says the amenity program at St. Regis Residences Sunny Isles spans more than 70,000 square feet across wellness, fitness, dining and entertainment, and presents the development as a private residential resort. Developer materials also describe an oceanfront infinity pool on the North Tower deck, which they call the longest in South Florida. A buyer guide on branded towers in the city notes that there is no hotel component. The St. Regis hospitality team would instead operate what is essentially a large, fully serviced private condominium, with butler service as a hallmark of the brand.

Established towers deliver their own versions of service. Legacy oceanfront buildings in Sunny Isles Beach commonly offer 24-hour security and valet, multiple pools, on-site dining, housekeeping and an oceanfront spa. Newer branded neighbors add beach service, cabanas and club lounges. What matters in a comparison is whether the amenities are ones you will use. Guides to the city's oceanfront tiers make this point directly: look past the view first and weigh building operations, reserve planning and the level of service you will actually use.

One caution applies to every amenity list on a building not yet finished. Descriptions reflect the developer's plans. Ask which spaces sit on which tower's deck, since the North Tower is where the headline pool is described, and ask what is shared between the two towers. In a resale building, by contrast, you can visit every amenity and see whether it is in use, in good repair and open when you would want it.

Floor plans are where new construction most often departs from older oceanfront towers. Buyer guidance on St. Regis Residences Sunny Isles describes residences with Italian kitchens, generous terraces, and many flow-through plans that capture both sunrise over the Atlantic and sunset to the west. The project's own materials mention private elevator and entry foyer access and fully finished residences, and some plans are described as having terraces with private pools or jacuzzis. Larger plans are reported to include service quarters and true family rooms, reflecting owners who expect long stays.

Resale towers vary widely. Some established oceanfront buildings in the city offer large three-, four- and five-bedroom homes, and a buyer can often find sizable plans there. The trade-off tends to be design vintage: ceiling treatment, kitchen configuration, window systems and terrace depth reflect the era in which a building was designed. Many resale owners renovate to bring a unit closer to current taste, which adds a step that a newly finished residence typically does not require.

For either path, read the plan itself rather than the marketing description. Check which direction the living areas face, how deep the terrace is, where the bedrooms sit relative to the water, and whether the layout is a corner or a through-line. Ask the developer for the specific residence line and its floor range. For a resale unit, ask for the as-built plan and any alterations approved by the association.

The water is the reason to look at this stretch of coast at all, and here the comparison is concrete. The official project website says the development takes in 435 linear feet of oceanfront, with soft white sand and the Atlantic directly in front of the towers. Sunny Isles Beach as a whole is a thin barrier island, framed by white sand on the ocean side and the Intracoastal Waterway behind it, so a tower's position and orientation determine whether a given residence looks to the ocean, to the Intracoastal, or both.

In practice, exposure is a line-by-line and floor-by-floor question. Guidance on the project notes that the choice of tower and then floor drives delivery timing and which amenity deck a buyer is buying into. Within either tower, an east-facing residence and a west-facing residence give very different daily experiences of the water. Buyers comparing against resale should also check how neighboring towers sit relative to a given unit, because an existing building has fixed neighbors, while a project under construction depends on how the surrounding skyline looks when the work is done.

The beach itself is worth examining on site. Standing at each address at different times of day shows how the sand, the shade and the sound of the surf compare. The St. Regis project describes a private beach club and gardens shared by its towers. Established buildings each have their own relationship to the beach, and visiting several in person is the most reliable way to understand the differences.

A useful comparison starts with priorities, not buildings. Decide how important occupancy timing is, how much you value a unit that is already finished and visible, and how much you want a brand-managed service culture. If you want to see exactly what you are buying, an existing tower allows it. If you want current design and a single hospitality operator across a large amenity program, a branded new building speaks to that.

Next, ask for documents rather than descriptions. For St. Regis Residences Sunny Isles, request the current residence lines available in the tower you prefer, the delivery schedule for that tower, the amenity plan by tower, and the draft condominium documents. For a resale building, request the association's governing documents, recent meeting minutes, the reserve information the association provides, and the rules on use and occupancy. Treat any number on a marketing page as something to verify with the seller or developer.

Finally, view as many of the contenders as you can. Seeing a finished residence at an established tower and a sales gallery or model for the new project on the same day sharpens the contrast in ceiling heights, glass, terrace depth and sound.
