The Residences at The St. Regis Costa Mujeres Resort

Under construction

The residences

The name licensed to this project and carried on the building. A brand is not a company: it holds no title, builds nothing and runs nothing.
St. Regis
The business the brand comes from — hotel, fashion, design, automotive, restaurant, club, or a developer’s own name.
Hotel
The larger planned community, resort or named development this project sits inside. A standalone building sits in none.
Costa Mujeres
How many separately titled homes this project sells, counting every kind it sells. Where it sells more than one kind, each is named and its own count given.
80
The kinds of home offered — villas, condos, penthouses, lots — and how they break down. Not how many, and not what interest is sold.
2–5BR residences and two-storey penthouses
Whether a hotel shares the site, the building is mixed-use, or it is residences only.
Hotel on site
When the project was first made public.
The developer's own project page and the November 2025 residences release were both read; neither states when the project was first made public. The earliest opened page describing it is a trade report of April 2024.
When its residences were first released for sale.
AB Living's own St. Regis Costa Mujeres page and the November 2025 residences release describe the residences without stating when they were released for sale.
When ground was broken on the site.
No opened page — developer project page, November 2025 release, April 2024 trade report — states a groundbreaking date.
Every handover date the project has been given, oldest first.
2026
When the residences were handed over to buyers.
Every opened page places the opening in the future; none records the residences as handed over.

How this project is structuredAB Living Group, the Spanish developer behind SHA Wellness, owns and develops the residential component beside its own St. Regis resort at Costa Mujeres. St. Regis is Marriott-licensed — the residences are not owned or developed by Marriott. Sordo Madaleno is the architect of record.

These projects carry a coordinate that is not their own site — a district node, or the nearest mapped feature — because pre-construction sites are not mapped.

Projects
  • Shared pins are real clustering, not errorSLS Harbour Beach and SLS Marina Beach carry the Novo Cancún district node, having previously been placed on the node OpenStreetMap identifies as the SLS Cancun hotel building itself; Mayaliah and AZULIK Residences both state Aldea Zamá as their location and share that district node. Where projects overlap on the map they genuinely overlap on the ground.
  • Two are proxies to an adjacent featureMondrian Residences Cancun is placed on Boulevard Kukulcan because Bay View Grand is not mapped; the Ritz-Carlton Punta Nizuc is placed on the Club Med Cancun node, the nearest mapped feature on the same point. Both are proxies to an adjacent feature, not the parcel itself.
  • Costa Mujeres and Aldea NizucThe three additional AB Living residential components share the Playa Mujeres district coordinate already used for the St. Regis; Aldea Nizuc carries the Punta Nizuc stretch of Blvd. Kukulcán, its published address being a kilometre marker.

These projects were announced to open on dates that have now passed, with no source confirming delivery.

Projects
  • Announced dates have passedSt. Regis Costa Mujeres was scheduled for early 2026, Mondrian Tulum for 2025, Mayaliah Tulum for 2024 and Nobu Tulum for the first quarter of 2025.
  • Each is held at the more conservative stageNo opened source confirms any of the four has delivered, so none is recorded as operating. Stage is set from the most recent source rather than the announcement, which means these four will move as soon as a post-opening source is found.

Should Sordo Madaleno be one company record nationally, or stay separate from the SOMA composite that carries it in Los Cabos?

Projects
  • Separate: different rolesHere Sordo Madaleno appears purely as architect of record on projects it does not own. In Los Cabos the credits carry SOMA · FibraSOMA · Sordo Madaleno as one record, a developer, architect and REIT combination that owns what it builds. Merging them would credit an architecture practice with ownership it does not hold.
  • One nationally: same practiceThe architecture practice is the same firm wherever it is credited. Left separate, the national registers show Sordo Madaleno twice and understate its footprint across Mexico; the combined record is credited on no project at all, because each of its three members is credited on its own.
