When someone asks us which is the most exclusive gated estate in the Maresme, the answer is almost always the same: Supermaresme. And although the name sounds familiar, very few people really know what it is like to live there, what kind of properties it holds or why it has established itself as one of the most sought-after residential areas in Spain.
Interest in this estate has grown noticeably in recent months, especially after the announcements about the refurbishment of Port Balís and the publication of the international report by the estate agency Barnes, which places the Maresme among the luxury locations most in demand by foreign buyers in 2026.
In this guide we explain in detail what Supermaresme is, what its history is, what kind of properties you will find there and why more and more international wealth-focused buyers are looking towards this private estate.
What Supermaresme is and where it is
Supermaresme is a private luxury estate located between the municipalities of Sant Andreu de Llavaneres and Sant Vicenç de Montalt, right on the Maresme coast, about 30 minutes by car from central Barcelona.
It was founded in 1973 by the Ferrer Klein family, who have run and managed the estate ever since. More than 150 houses have been built since its creation, a small gated residential community that has stayed true to its original philosophy: privacy, exclusivity and extreme care for the setting.
Unlike other residential areas of the Maresme that have grown organically, Supermaresme was born as a planned development project, with generous plots, private roads and its own planning code that has protected its character for more than five decades.
Why they call it “the Beverly Hills of Barcelona”
The nickname is no accident. Supermaresme brings together characteristics that very few European estates can offer at once:
- A concentration of income per capita among the highest in Spain
- Total privacy guaranteed by its gated layout
- 24-hour security and concierge
- Open views of the Mediterranean from most plots
- A privileged microclimate, mild all year round
- Genuine proximity to Barcelona, the airport and Port Balís
Its residents include business owners, athletes, diplomats and figures from the cultural world, drawn by the unusual combination of discretion and quality of life.
In that sense, Supermaresme fits perfectly with the trends in the luxury property market in the Maresme: less display, more genuine privacy and an increasingly wealth-focused buyer profile.
The features that make this estate unique
Plots of at least 2,000 sqm
The Supermaresme planning code sets a minimum plot size considerably larger than that of any other estate in the area. This guarantees generous distances between homes, mature gardens and a sense of space that is hard to replicate.
On the largest plots it is not unusual to find areas of more than 5,000 or even 10,000 sqm, with private woodland, several separate garden areas and no immediate neighbours at all.
Security and integrated services
The estate has 24-hour security and concierge, professional maintenance of roads and communal areas, and its own team to handle any issue arising in the homes.
This level of service is particularly attractive to international buyers who do not live in the property all year round and want the peace of mind of knowing the house is well cared for in their absence.
Microclimate and natural setting
Supermaresme sits on a south-facing hillside, with sea views and sheltered from northerly winds by the coastal range. That position creates an exceptional microclimate, with mild temperatures all year and many more days of sunshine than the local average.
A genuine connection to Barcelona
Although it feels secluded, Supermaresme is perfectly connected. The C-32 motorway gets you to central Barcelona in approximately 30 minutes and to the airport in under 45.
That genuine proximity is precisely what has allowed many families to stop using Supermaresme as a second home and settle there all year round.
Types of property in Supermaresme
One of the estate’s great strengths is its architectural variety. Carefully updated houses from the seventies and eighties sit alongside recently built contemporary villas.
The most representative types include:
- Classic Mediterranean villas, with a pool, generous terraces and a mature garden
- Contemporary houses with clean lines, large windows and architecture that opens onto the outside
- Properties with a spa, heated indoor pool and private gym
- Houses with a winter and a summer kitchen, multipurpose rooms and separate guest suites
- Estates with a tennis or padel court or small plantations
The common denominator is build quality, high-end finishes and careful integration with the setting.
How much a house in Supermaresme costs
The price in Supermaresme depends on three main factors: plot size, the quality and aspect of the views, and the condition of the house.
According to the Global Property Handbook 2026 published by the international agency Barnes, in the highest luxury segment of the Maresme the square metre sits between 5,500 and 7,500 euros, while premium villas with sea views and large plots can exceed €8,500 to €10,000/m².
Applied to Supermaresme, the indicative ranges are as follows:
| Property type | Price per sqm | Indicative total price |
|---|---|---|
| Standard villa | €5,500 – €7,500/m² | €2.5m – €5m |
| Premium villa with views | €8,500 – €10,000/m² | €5m – €12m |
| Exceptional transactions | Over €10,000/m² | up to €17m |
These ranges are indicative. The reality is that in Supermaresme every transaction is highly particular and the micro-location within the estate itself can move the price significantly.

Port Balís: the change that is coming
The Port Balís concession, in force since the 1990s, ends in 2026. The new concession provides for more berths for large vessels, a commercial refresh and an updated dining offer.
This transformation matters to Supermaresme for two reasons:
- Port Balís is the reference marina for residents of Supermaresme and Rocaferrera
- A thorough refurbishment of the marina strengthens the appeal of the whole area and, predictably, its property values
The sector is already reacting: recent analyses suggest the new concession will boost property investment in the surrounding estates, especially in the premium villa segment with sea views.
A comparison with other luxury estates in the Maresme
The Maresme has several high-end estates. Each has its own profile and strengths. This comparison helps place Supermaresme within the wider picture:
| Estate | Town | Dominant property type | Privacy |
|---|---|---|---|
| Supermaresme | Sant Andreu de Llavaneres | Villa with plot from 2,000 sqm | 24-hour concierge |
| Rocaferrera | Sant Andreu de Llavaneres | Villa with a generous plot | High |

| Mas Coll | Alella | Villa | High |
| Sant Berger | Teià | Villa | 24-hour security |

Who buys in Supermaresme today
The buyer profile has changed a great deal in recent years. It used to be dominated by the second home of Barcelona families who spent seasons and holidays in the area. Today, a growing share of buyers have made the property their main residence.
We see three main profiles:
- International families looking to settle near Barcelona, with children in international schools and flexible or remote work
- National wealth-focused buyers who see the estate as a long-term safe-haven asset
- Premium second-home investors, who keep the house as a secondary residence but use it for more months of the year than before

How buying in Supermaresme really works
One important characteristic: a significant share of transactions close away from open portals. This is down to the priority the families themselves place on discretion.
That has three practical implications for a buyer:
- The supply visible on portals does not reflect everything that is genuinely available
- Access to local information and established relationships in the area is decisive
- A well-planned purchase requires time, judgement and professional guidance
At Maresme Realtors we handle a good share of these transactions confidentially, and we understand that in this segment the quality of the process matters as much as the quality of the asset.

Conclusion: an estate where luxury is measured in privacy
Supermaresme does not compete with other estates on size, number of properties or visibility. It competes on what is no longer being built: generous plots, planned development, integrated services and a setting that has been protected for decades.
In a Maresme going through deep transformation, with the Port Balís refurbishment and the constant arrival of international buyers, this estate stays true to what made it a benchmark: the unusual combination of discretion, exclusivity and genuine quality of life.
For many buyers, that is precisely what defines real luxury today.
