For the buyer who wants the mechanics of a pre-construction decision, stated plainly.
This page explains. Whether the building suits you is a separate conversation. Contact the desk at Miami Dossier for the current position on any building we cover.
The Ritz-Carlton Residences, South Beach is a 30-residence, 15-story oceanfront pre-construction project at 1671 Collins Avenue in South Beach. The developer is Sobe Sky Development, with Flag Luxury Group, and sales launched in February 2025 with delivery planned for 2027. Whether it suits your goals comes down to verifiable facts: the developer's delivered record, the construction timeline, the budget and reserve structure, the brand license terms, and how the unit compares to current South Beach inventory. This is mechanics, not advice. The desk does not predict appreciation; it verifies what can be verified.
Buying pre-construction is not buying a condo. It is buying a contract to buy a residence at a future date, at terms fixed today. That contract has moving parts, and each one is checkable.
First, delivery certainty. The building is pre-construction, which means the question is who builds it and on what schedule. Permits, the general contractor, and the developer's capitalization are the three things your counsel and the desk verify against the offering documents.
Second, entry terms relative to comparable resales. A 30-unit oceanfront collection in South Beach competes with existing branded inventory. The desk keeps the current file on pricing and availability as the developer releases it, so your comparison rests on live numbers, not launch-day material.
Third, carrying cost during construction. Deposits are staged across the construction period and held by the developer's escrow agent. You carry no mortgage until closing, but your capital sits in escrow. Florida condominium counsel can walk you through how escrow works for this project.
Fourth, exit optionality. A pre-construction contract can usually be assigned to another buyer, but only on the developer's terms. The assignment clause in the purchase agreement decides whether you can sell the contract before closing, and at what fee. Read it before you sign.
From the census record and the developer's factsheet, the confirmed facts:
Address: 1671 Collins Avenue, Miami Beach, FL 33139.
Scale: 30 residences across 15 stories, described as beach houses, from one-bedroom to five-bedroom layouts.
Two duplex penthouses with private rooftop terraces, each with an individual outdoor pool and kitchen.
Residences: private elevator with direct entry in most residences, wrap-around terraces with glass railings in most, 10-foot ceilings, floor-to-ceiling windows, custom French white oak floors, Lutron lighting control.

Hotel connection: direct access to the Sagamore, the newly renovated all-suite addition to The Ritz-Carlton, South Beach, with restaurant and beach club culinary programming by Michelin-starred chef José Andrés, two beachfront pools with 12 semi-private cabanas, and a residents' beach club with dedicated cabana service.
Owner benefits: residence owners receive benefits at more than 700 participating hotels in Marriott International's luxury portfolio, including the Ritz-Carlton, St. Regis, and Edition flags, based on availability.
This matters more than most buyers realize. The developer's own materials state it plainly: The Ritz-Carlton Residences, South Beach are not owned, developed, or sold by The Ritz-Carlton Hotel Company. Sobe Sky Development, LLC uses the Ritz-Carlton marks under a license.
A license is a contract with a term, conditions, and renewal mechanics. The buyer question is what the license covers, how long it runs, and what happens to services and branding if the license changes. These are document questions, answered in the offering materials and verified by counsel, not by a brochure. Your counsel should confirm the license term, the services conditioned on it, and any disclosure about changes to amenities or branding.
A serious buyer compares this project against its real competitors, not against the whole market. Two are worth naming.
The Shore Club Private Collection is also in South Beach, developed by the Witkoff Group with Monroe Capital and marketed by Douglas Elliman Development Marketing. It carries 45 to 49 residences under the Auberge Resorts Collection flag, is under construction, and is expected to complete in 2026-2027.
The Perigon sits at 5333 Collins Avenue in Mid-Beach, from Mast Capital and Starwood Capital Group, also marketed by Douglas Elliman. It topped out in March 2026, holds 73 residences, is reported more than 75 percent sold, and is expected to deliver in 2027.
The comparison to run is mechanical: unit mix and residence count, delivery date and construction status, the terms of the brand arrangement, amenity depth, and the current release terms. The desk holds the current file on all three, so the numbers in your comparison are live.
Reading the wider South Beach condo landscape helps too. South Beach remains the district where branded residences carry the strongest identity premium, and where the resale record for comparable buildings is the longest.
Before anything is signed, the buyer works through this list with counsel:
1. Developer record: what Sobe Sky Development and Flag Luxury Group have delivered, and on what timeline.
2. Offering documents: the budget, reserve funding, escrow terms, assignment clause, and the brand license.
3. Construction status: permits in hand, the general contractor, and the current milestone against the delivery target.
4. Comparable set: recent resales of comparable South Beach branded residences, with the desk's current file.
5. Insurance and flood: the elevation certificate, the master policy, and your own HO-6 quote from a licensed broker.
6. Entity and tax structure: if you plan to buy through a trust or entity, arrange it before you sign. Details are in our separate guide.
Verification is the whole job. Confirm the delivery target and the current construction milestone with the developer's own materials. Confirm the brand license term with counsel. Confirm the unit's release terms with the desk's current file. Confirm insurance quotes with a licensed broker before you rely on any assumption about cost. And confirm that the purchase agreement's assignment, escrow, and closing terms match what you were told. Anything you cannot confirm in writing does not count as a fact.
The desk keeps the current file on The Ritz-Carlton Residences, South Beach: plans, pricing, and availability as the developer releases them. If you want the private file, ask.
