St. Regis Residences, Sunny Isles Beach: The Oceanfront Buyer's Guide (Pre-Construction 2026)

Sunny Isles Beach has spent the last two decades becoming South Florida's densest concentration of branded oceanfront towers — Porsche, Armani, Bentley, Aston Martin, Ritz-Carlton, Acqualina. Into that skyline comes one of the most storied names in luxury hospitality, and it arrives directly on the sand.

The St. Regis Residences, Sunny Isles Beach is rising at 18801 Collins Avenue as a two-tower, ~62-story oceanfront development on roughly 4.7 acres with about 435 linear feet of beach frontage. Developed by Fortune International Group and Château Group, designed by Arquitectonica with interiors by Patricia Anastassiadis, it brings the 120-year-old St. Regis name — and its signature butler service — to the Sunny Isles shoreline for the first time.

Unlike some St. Regis properties, this is a residential-only interpretation of the brand — there is no on-site hotel sharing the amenity deck. The roughly 70,000 square feet of wellness, dining, and entertainment space, the private beach club, and the full-time staff exist for owners, not transient guests. For the oceanfront luxury buyer, that distinction is a large part of the pitch.

Two Towers, One Oceanfront (Read This First)

St. Regis Sunny Isles is delivered as two matching oceanfront towers — a South Tower (broke ground first, addressed 18801 Collins) and a North Tower (18805 Collins). Both rise to roughly the same height and share the same architect, interiors, and brand service standard.

The most important thing to understand as a buyer is timing and exposure, not a hard product split between the towers:

• The South Tower broke ground first (site work began in 2024) and is currently targeting an earlier delivery — the natural choice if you want to take occupancy sooner.
• The North Tower follows on a later timeline and is home to the headline amenity: developer materials describe the longest infinity pool in South Florida on its deck.

Because the towers are phased, "St. Regis Sunny Isles pricing" and availability will read differently depending on which tower and release you are looking at. Always confirm you are comparing the same tower, line, and exposure.

The Architecture: Arquitectonica on the Sand

Arquitectonica is arguably Miami's most consequential architecture firm — the studio that helped define the modern South Florida skyline, from Brickell to the beaches. For St. Regis Sunny Isles it delivers a pair of tall, slender oceanfront towers engineered to maximize water views and cross-ventilation, with deep terraces and floor-to-ceiling glass across the ocean exposures.

Interiors are led by Patricia Anastassiadis, the acclaimed Brazilian designer known for warm, textural, hospitality-grade interiors. Her work sets the tone across the residences and the amenity spaces — a softer, more residential counterpoint to the tower's glass-and-steel envelope.

The combination — a globally recognized Miami architect, a hospitality-forward interior designer, and the St. Regis brand standard — is the differentiator St. Regis is selling against a Sunny Isles corridor already thick with branded product.

Location: The Branded-Tower Stretch of Sunny Isles

18801 Collins Avenue sits mid-island in Sunny Isles Beach, on the ocean side of Collins, in the heart of the city's branded-tower corridor.

The trade-off versus a Brickell or downtown address is deliberate: Sunny Isles is a beach-first, resort-paced enclave rather than an urban core. In exchange for being further from Miami's business district, you get direct sand, wide ocean exposures, and proximity to two of South Florida's premier shopping destinations — Aventura Mall and Bal Harbour Shops — both a short drive away.

---

The Residences

Across both towers, residences are delivered fully finished with Anastassiadis-specified interiors and wide ocean or Intracoastal exposures. Signature features generally include:

• Private elevator access and entry foyers on most residences
• Floor-to-ceiling impact glass with direct ocean views
• Expansive private terraces with summer kitchens on many lines
• Deep floor plans engineered to bring ocean light through the home
• Italian kitchens with premium integrated appliance packages
• Primary baths with marble finishes, freestanding tubs, and oversized showers
• Sky Villas and Penthouses — full-floor trophy homes with private pools, jacuzzis, summer kitchens, and dual east/west terraces

Floor Plan Mix (approximate)

• Two- to four-bedroom residences: roughly 1,785 to 5,674 sq ft across the towers (2BR from the high-1,000s / low-2,000s; 4BR into the mid-4,000s)
• Half-floor residences: larger combined layouts offered in the upper stack
• Sky Villas & Penthouses: roughly 7,500 to 10,000+ sq ft, full-floor, with private pools and separate entrances

Unit dimensions and line counts vary between the two towers and by release — confirm the exact square footage and layout for the specific line you are considering.

---

Amenities: A Private Oceanfront Resort

With no hotel sharing the building, the roughly 70,000 square feet of amenities are private to residents and their guests. Published and expected amenities include:

• Private beach club with cabanas, loungers, umbrellas, a bar and grill, and direct beach service
• Multiple pools — including a members' pool, a lap pool, and a tower pool, plus a kids' splash zone
• The longest infinity-edge pool in South Florida on the North Tower's sunset deck, with a sunken lounge, dining terrace, and pool bar
• Spa and wellness center with treatment rooms, sauna, steam, and hammam
• Oceanfront fitness center
• Signature restaurants and lounges, a wine vault, and a cognac room
• Landscaped events lawn and pavilion

St. Regis Butler Service

The operational signature of the brand is the St. Regis Butler Service — a tradition introduced at the original St. Regis New York in 1904 by John Jacob Astor IV. In a residential context it means the anticipatory, personalized service owners value most: packing and unpacking, garment pressing, in-residence dining coordination, and a standing point of contact who has the residence ready before you arrive. For seasonal and lock-and-leave owners, this is a core part of what the brand premium buys.

The Developer Team

• Fortune International Group — a Miami-based developer, brokerage, and sales-and-marketing powerhouse with a long South Florida track record across Sunny Isles and Miami Beach. Its in-house sales arm gives the project deep local market reach.
• Château Group — a family-run developer with a multi-generational track record on the Sunny Isles oceanfront, known for delivering high-end branded and boutique towers along Collins Avenue.
• St. Regis / Marriott International — the brand operator, bringing the service standard and brand standards on a residential (non-hotel) license.

The partnership has continued to secure construction financing as the project advances — the North Tower reached a significant construction loan in 2026, a signal that the towers are being underwritten through delivery rather than stalling at the sales phase. A proven, locally rooted development team is one of the most underrated factors in pre-construction risk.

---

Construction Status & Timeline

As with any phased project, the two towers are on different delivery clocks. Confirm the specific closing timeline for the exact tower and unit you are considering — it drives your deposit schedule and carrying-cost planning.

---

Pricing Reality

• Entry pricing for two-bedroom residences has been offered from roughly $3.9M–$5M, depending on tower, floor, and exposure.
• Three- and four-bedroom residences run into the $8M–$11M+ range as size and elevation climb.
• Half-floor residences have been offered from around $15M, with Sky Villas and penthouses commanding materially more.

Published pre-construction pricing is a snapshot, not a quote. The two towers price differently, availability and developer incentives shift with each release, and the best current pricing rarely matches what circulates on aggregator sites. Confirm live numbers through the sales gallery and your buyer's agent.

Who This Building Is For

1. The Oceanfront Primary-Residence Buyer

You want to wake up on the sand with wide ocean views, full beach-club service, and butler support — in a residential-only building that isn't shared with hotel guests. The larger three- and four-bedroom lines and Sky Villas are built for you.

2. The Brand-Loyal Seasonal Owner

You want a lock-and-leave oceanfront residence under a name you trust, with butler service that has the home ready on arrival. A two- or three-bedroom in whichever tower delivers on your timeline is the efficient way in.

3. The Sunny Isles Investor

You are betting on the durability of Sunny Isles' branded-oceanfront niche. Branded residences by proven developers have historically defended value better than unbranded product through cycles — though the premium HOAs on a fully amenitized oceanfront tower absorb part of gross rent, so model income conservatively and confirm the building's leasing rules.

---

Cost of Ownership

Beyond purchase price, budget for:

• HOA fees: A branded, heavily amenitized oceanfront tower with a beach club and full butler staffing sits at the higher end of Sunny Isles dues. Model your specific unit's monthly assessment carefully before contracting.
• Property taxes: Miami-Dade ad valorem taxes generally run ~1.6–2.0% of assessed value annually.
• Insurance: Condo HO-6 plus wind coverage varies by floor and unit size; oceanfront exposure matters here.
• Deposit schedule: Florida pre-construction typically stages deposits from contract through closing — understand exactly what is at risk and when, and note the two towers may run different deposit calendars.

A realistic all-in carrying cost for a branded oceanfront residence like this lands in the low-single-digit percentage of purchase price per year. Build the full model — HOA, tax, insurance, and the opportunity cost on staged deposits — not just the headline price.

Frequently Asked Questions

Is there a St. Regis hotel in the building?

No. St. Regis Sunny Isles is a residential-only development — there is no on-site hotel. The amenities, beach club, and staff serve owners and their guests, not transient hotel guests. (This is different from the St. Regis Bal Harbour, which is an oceanfront hotel-and-residences property nearby.)

How many towers and units are there?

Two towers, each roughly 62 stories and about 750 feet tall, with approximately 170 residences per tower (~340 total). Published counts vary somewhat by source and release as plans finalize.

Who is the architect and interior designer?

Arquitectonica is the architect; Patricia Anastassiadis designs the interiors.

When will it be delivered?

Guidance points to roughly Q4 2028 for the South Tower and Q4 2029 for the North Tower. Confirm the date tied to your specific unit and tower.

What's the deal with the infinity pool?

Developer materials describe the longest infinity-edge pool in South Florida on the North Tower's sunset deck — one of the project's headline amenities, alongside a private beach club and multiple additional pools.

Are residences delivered furnished?

Fully finished but unfurnished — kitchens, baths, flooring, and fixtures are included; furniture is the buyer's responsibility. Some penthouse and Sky Villa offerings include designer-selected furnishing packages; confirm per unit.

Can I rent my residence out?

Long-term leasing is generally permitted subject to the condo documents; short-term/hotel-style rentals are not part of this residential building. Review the declaration for exact minimum lease terms before you buy for income.

How to Buy at St. Regis Residences, Sunny Isles

Pre-construction at this level is a multi-year commitment with staged deposits and real tax, insurance, and HOA implications. Before contracting:

1. See the actual current inventory and pricing — by tower, line, and exposure. The public numbers are rarely the live ones.
2. Decide South Tower vs. North Tower first, then choose the floor. The tower decision drives your delivery date, deposit calendar, and which amenity deck you're buying into.
3. Compare head-to-head with the other ultra-luxury Sunny Isles oceanfront pre-cons — see the top luxury Sunny Isles condos and the Estates at Acqualina guide. Each targets a slightly different buyer.
4. Contrast it with the brand's Miami sibling — The St. Regis Residences, Miami in Brickell is bayfront and residential-only in an urban core, while Sunny Isles is directly oceanfront and resort-paced. Same brand and butler service, very different setting.
5. Model the full cost of ownership and understand your deposit at risk under Florida pre-construction law.
