The St. Regis Residences Sunny Isles Beach: ten reasons buyers choose it

The St. Regis Residences, Sunny Isles Beach is two 62-storey oceanfront towers on roughly 4.7 acres with roughly 435 feet of beach at 18801 Collins Avenue, by Fortune International Group and Château Group, designed by Arquitectonica with interiors by Patricia Anastassiadis, residence only with no hotel. The South Tower foundation was poured in July 2026. Here is what the buyers who choose it are choosing.

Written by the desk at Miami Dossier from the developer's published material and the public construction record, cross-referenced across several sources, with anything unconfirmed flagged. The desk works in English, Spanish and Portuguese and does not represent the developer. All notes from the desk.

The Note
30 August 2026

The desk at Miami Dossier covers a small number of Miami buildings closely rather than the whole market lightly. The St. Regis Sunny Isles is one the desk is asked about every week, and this note is compiled from the developer's published material and the public record rather than from a brochure summary. It is the list of reasons buyers give when they choose this building, in the order we hear them, with the facts behind each one.

One. Roughly 435 feet of beach on 4.7 acres

The site at 18801 Collins Avenue carries roughly 435 linear feet of oceanfront on roughly 4.7 acres, which on the Sunny Isles strip, where most towers sit on narrow lots, is a wide piece of sand. The desk at Miami Dossier reads that as the first reason before the brand.

Two. A residence-only St. Regis, with no hotel

Two towers, both residential only, with no hotel and no transient use, managed by the St. Regis Hotel Company for the residents alone. Butler service, in-residence dining and the brand's traditions come to the residents rather than the residents living above a hotel lobby.

Three. Arquitectonica's twin elliptical towers

Arquitectonica designed the two towers as curvilinear, yacht-inspired forms of 62 storeys and roughly 750 feet, oriented so that most residences see the ocean, the Intracoastal and the city at once.

Your situation is specific. Tell the desk in one message and we will say what applies to you, what does not, and who to speak with.

Four. Patricia Anastassiadis on the interiors

The São Paulo designer, best known for five-star hospitality across Brazil and beyond, designed the residences, the amenity and the common rooms. It is one of the few Miami towers with a Brazilian design lead, and it shows in the warmth of the palette.

Five. Roughly 320 residences across two towers

Published counts sit around 170 in the South Tower and 150 in the North, roughly 320 in all, from two to four bedrooms with Sky Villas and penthouses above. Plans are reported from roughly 1,850 to 5,700 square feet in the typical lines and from roughly 6,600 to more than 10,000 in the villas and penthouses.

Six. More than 70,000 square feet of amenity

A private residential resort in the published material: pools, a beach bar and grill with beach service, a spa and wellness programme, a business club with a boardroom, private offices and a traders' room, and, in the North Tower, an infinity pool described as the longest in South Florida.

Seven. Marriott's residences reservation service

Ownership includes the opportunity to join Marriott International's residences hotel reservation service, with status and privileges at hotels worldwide, per published material.

Eight. Between Bal Harbour Shops and Aventura

Sunny Isles Beach sits between Bal Harbour Shops to the south and Aventura Mall and the marinas to the west, roughly equidistant from Miami and Fort Lauderdale airports, on the tallest oceanfront row in South Florida.

Nine. Two towers, two timelines

The South Tower broke ground first and is guided for late 2028; the North Tower is scheduled to break ground in late 2026 and is guided for 2029. A buyer chooses between sooner keys and the tower with the headline pool.

Ten. Fortune and Château, with the foundation poured

Fortune International Group and Château Group have delivered together before in Sunny Isles, with Coastal Construction as general contractor. The South Tower's mat foundation was poured over three days in July 2026, roughly 10,000 cubic yards of concrete, and the tower goes vertical later this year. The desk at Miami Dossier holds the delivery history and shares it on request.

The questions around the building

Most of the people who ask the desk at Miami Dossier about The St. Regis Residences Sunny Isles Beach are not only choosing a building. They are moving to Miami from New York, California, London, Bogotá, Mexico City or São Paulo, or adding a Miami position to a portfolio held elsewhere, and the building question sits inside a larger one: how to buy new construction in Miami, how to hold it, and what changes when you do.

The desk keeps short notes on the parts that come up every week: how buying preconstruction in Miami actually works, what a normal deposit schedule looks like, whether you need to be in Miami to buy, whether a foreign buyer can get a mortgage, what taxes a foreign buyer pays on a Miami condo, and the Florida state income tax question for anyone relocating from a high-tax state. For buyers arriving from a specific market there are notes for Bogotá, Mexico City and London, and a broader one on why so many wealthy families are moving to Miami.

Read the ones that apply, then bring the rest to the desk at Miami Dossier. It usually takes one conversation to see how The St. Regis Residences Sunny Isles Beach fits the move, or whether another building fits it better.

A Note on Advice

This note is general information for people considering Miami, written by a real estate desk, not by a law or accounting firm. Nothing here is legal, tax, immigration or investment advice, and it is not a substitute for advice on your own circumstances. Rules change, treaties differ by country, and the right answer for one family is the wrong answer for another.

Speak with your own attorney and CPA before you commit to anything. If you do not have one who works with international buyers in Florida, the desk is glad to recommend an attorney, a CPA or an adviser suited to your situation, and to sit in the first conversation so that nothing is lost in translation.

The Desk

Everything in this note has a solution.

Structure, financing, currency, timing, the right building and the right line: the desk works through these questions with international buyers every week, and the answer is nearly always that it can be done, in order, without surprises. If Miami is on your mind, as a home or as an allocation, we would be glad to share what we are seeing, privately, and to start with the question this note did not answer.
