St. Regis Marbella: New Hotel & Branded Residences
IN SUMMARY
St. Regis Marbella will be a beachfront hotel and residential complex in Las Dunas, East Marbella. It will include a 169-room hotel and 151 branded residences with two to five bedrooms and sizes starting from 150 m². Developed by Sierra Blanca Estates and Platinum Estates under Marriott's St. Regis brand, the project represents an investment of more than 500 million euros and is expected to open in 2031. Prices and reservation terms have not yet been published, and it should not be confused with St. Regis Residences Casares, which is already on the market in Finca Cortesín.
St. Regis Marbella now has a date: the hotel and residential complex in Las Dunas, East Marbella, is expected to open in 2031 with a 169-room hotel and 151 branded residences. The news was confirmed on 20 October 2026, when the mayor attended the signing of the agreement between the developers and Marriott International.
It will be the first St. Regis hotel on the Costa del Sol and a new addition to a branded residences market that continues to grow.
Below, we explain what is known about the project, what remains unconfirmed, how it differs from St. Regis Casares and what options are currently available if you are looking for a branded residence in Marbella.

Las Dunas: the site and the history of the project
A beachfront site in East Marbella
The development will occupy more than 160.000 m² of land by the sea in the Las Chapas area. According to the mayor, around 110.000 m², close to 69%, will be allocated to public spaces. The privately owned hotel and residences will be built on the remainder. This is significant because it will influence both the density and character of the development. Marbella Town Hall also links the project to improved connections in the area and reduced traffic pressure.
A project with a long history
The hotel was first announced in 2016 under another Marriott brand, W Hotels, and its planning process continued for years, as reported by local media including Marbella24horas. The agreement between Platinum Estates and Sierra Blanca Estates was announced in June 2025, and St. Regis has now been confirmed as the brand. During that time, the planned investment has risen from around 300 million to more than 500 million euros.
The 151 residences: what we know
The residences will have between two and five bedrooms and range from 150 to 1.000 m². According to the information released so far, they will have independent access and will be able to benefit from hotel services.
That is the defining feature of branded residences: privately owned homes with the services associated with a five-star hotel, managed by an international brand. If you would like to understand the model in more detail, you can read our guide to branded residences on the Costa del Sol.
What is still unknown
As far as we know, prices have not yet been published. The distribution of property types by building, reservation and payment terms, and the sales launch date also remain unconfirmed.
Timeline: when will St. Regis Marbella open?
The hotel and residences are expected to open in 2031. According to the announcement, work is also expected to begin this year.
What we will be watching closely
At Marenco Real Estate, we will monitor the release of prices, floor plans and reservation terms, and we will inform you as soon as the developer makes them public.
St. Regis on the Costa del Sol
It is important not to confuse the two St. Regis projects on the Costa del Sol. St. Regis Residences Casares is a collection of 46 residences within the Finca Cortesín resort. It is already on the market, with prices starting from 2,8 million euros. There is no St. Regis hotel attached to the project: the residences form part of a resort with its own hotel, Hotel Finca Cortesín. Las Dunas, by contrast, will combine a beachfront hotel and residences, but has not yet published prices or a sales launch date.
Although there is no hotel under the St. Regis brand, the Casares project has more than 1.200 m² of amenities dedicated to residents:
- Residents' club: lounge, library with fireplace, cinema room, billiards and games room, children's room and meeting room.
- Dining and social life: bar, fully equipped kitchen for private events, wine cellar and outdoor fire areas.
- Sport: heated outdoor pool, indoor pool, gym, and yoga and Pilates rooms.
- Wellness: spa with hammam, sauna, massage room, halotherapy room and experience shower circuit.
Residents also benefit from the wider Finca Cortesín resort, with its golf course, beach and tennis clubs, and several restaurants. If you are interested in the area, do not miss our Finca Cortesín Area Guide.

What this means for the Marbella market
A new benchmark in East Marbella
The arrival of St. Regis confirms the interest of major international hotel brands in Marbella and draws attention to East Marbella. Until now, this area has been less closely associated with the ultra-prime segment than the Golden Mile. In our view, the project will strengthen the perception of the wider area and support demand for high-quality property nearby.
If you are looking for a branded residence with a clear timeline
With Las Dunas still around five years away and no prices announced, buyers looking for this type of property already have alternatives on the market. One is Armani Residences in Nagüeles, where construction has started and planning permission has been granted. It is developed by Sierra Blanca Estates, one of the developers behind St. Regis Las Dunas. In our complete analysis of the Armani project, you will find indicative prices, payment terms and the timeline. You can also view the available units in Nagüeles.
