Infrastructure Transformation in Marbella: How New Projects Are Changing the City and the Real Estate Market

Marbella is changing, and not only through new residential projects and the arrival of global brands. Behind the glamour, a less visible but no less important transformation is unfolding: a large-scale upgrade of infrastructure. Water supply, roads, public spaces, urban planning—everything is riding a wave of investment that will shape the city’s look for decades to come. For buyers and investors, this is an important signal, because the quality of infrastructure directly affects both everyday life and property values. In this article, we will look at the key areas of Marbella’s infrastructure transformation and what they mean for the market.

Why infrastructure matters to the buyer

Before moving on to specific projects, it is worth understanding the connection between infrastructure and real estate. It is direct and tangible.

Luxury housing is closely tied to infrastructure at the destination level. When a neighborhood attracts investment in roads, water, public spaces, and five-star hotels, the overall level of service and convenience rises. In turn, this means that buyers of premium housing expect—and are willing to pay for—areas that provide this level.

The formula is simple: location plus infrastructure equals a premium. A home in a good location, next to an area attracting serious investment, is essentially a purchase of future value. That is why it is important to monitor infrastructure transformation not only for city authorities, but for anyone considering buying property.

Water: an investment in resilience

One of the most significant, though also the least visible, areas is water infrastructure. After several years of drought along the coast, the issue of reliable water supply moved to the forefront.

Major changes are underway here. The European Investment Bank has approved a loan of 175 million euros to modernize the Costa del Sol water infrastructure, which is managed by the company Acosol. These investments will affect about one million residents across eleven municipalities, including Marbella, and in the summer season the number of people who benefit exceeds 1.4 million.

The program covers a wide range of work: modernization of water production and distribution systems, upgrading wastewater treatment plants, replacing more than 30 kilometers of water pipes, and building a new water storage reservoir. Special attention is given to Marbella’s desalination plant, which will be able to generate renewable energy for its own consumption. Water reuse networks are also being expanded.

These measures are part of a larger plan. In 2024, an investment plan of 348 million euros was approved to address the region’s water challenges following a series of droughts. All of this is intended to strengthen the resilience of water supply to climate change, reduce water losses, and ensure reliable water supply for the future.

For a property buyer, this is an important signal: the region is making a serious investment in solving one of the few real long-term problems on the coast, strengthening its resilience and appeal.

Urban planning transformation: a new plan

The second fundamental direction is urban planning. As we discussed in detail in a separate article, Marbella is receiving a new master urban planning plan, PGOM, the first modern document of this kind in decades.

The importance of this is hard to overstate. The new plan involves reclassifying about 12 million square meters of land, which will open up opportunities for developing new residential areas, commercial spaces, and infrastructure. Among the plan’s goals are reorganizing traffic in the center of Marbella and improving traffic flows.

One consequence of this transformation is that Marbella is expanding inland, away from the coast. Neighborhoods a few kilometers from the sea, where property is more affordable today and life is calmer, may in the long run see a noticeable increase in price as infrastructure develops. For a forward-looking buyer, this creates opportunities to enter early.

Public spaces and the coastal area

The third direction is the quality of the urban environment: public spaces, promenades, and green areas.

A clear example is the Las Dunas area urbanization project in the Las Chapas district in East Marbella. Approved works worth about 23.5 million euros include not only the resort project itself, but also the creation of new public spaces, pedestrian areas, cycle lanes, drainage systems, improvements to roads, and upgrades to engineering networks. Special attention is paid to restoring the dunes of the natural reserve and protecting biodiversity.

This approach is indicative: modern projects in Marbella increasingly combine private investment with improvements to public infrastructure and care for the environment. This reflects a more mature development model in which not only the developer benefits, but the city as a whole.

Neighboring Estepona set a high standard here by updating the promenade and turning it into a single coastal route of more than 15 kilometers, as well as renovating the historic center. Marbella is moving in a similar direction.

Roads and connectivity: an unresolved issue

Not everything in the infrastructure picture is unambiguously positive, and a honest discussion requires mentioning the challenges as well.

Road connectivity remains a challenge. The main coastal highway, A-7, is the artery of the coast, connecting Malaga with Torremolinos, Benalmádena, Fuengirola, and Marbella. During peak hours, it experiences heavy congestion, and a number of projects to expand it and modernize complex interchanges were postponed. For drivers, this means that for the near future, it is worth allowing extra time on the road, especially during morning and evening peak hours.

There is also a paid alternative, the AP-7 highway, which is usually freer and saves time, although it is not free. The question of canceling or reducing the toll for this road is periodically raised and remains a topic of discussion.

For those who value connectivity, it is also useful to know about the Cercanías rail line connecting Malaga with Fuengirola, which allows you to bypass coastal traffic jams. There is also discussion of the long-standing idea of extending the railway along the coast to Marbella and Estepona, which would be a significant improvement, although specific timelines for such a project have not yet been set.

The honest picture is this: connectivity is an area where the coast still has room to grow, and a potential buyer should take into account the transport situation of the specific location.

A hotel renaissance as part of the transformation

Another direction closely linked to infrastructure is a wave of investment in the hotel sector. Marbella is experiencing a real hotel renaissance: iconic hotels are being updated, global brands are arriving, and branded residences are being built.

Upgrading such landmark properties as hotels in East Marbella, the arrival of world-class brands—everything raises the overall level of service in the area: better restaurants appear, higher standards are introduced, and more conveniences are offered. And this directly affects the attractiveness of surrounding real estate and its value.

What this means for the real estate market

If we put everything together, Marbella’s infrastructure transformation brings several important takeaways for the market.

Strengthening long-term resilience. Investments in water, engineering networks, and urban planning solve real problems and make the city more resilient to future challenges. This strengthens the market’s foundation.

Growth in the value of neighborhoods affected by investment. Locations next to major infrastructure and hotel projects gain direct benefits for property values. East Marbella, with its projects, is a good example.

New opportunities in inland areas. As the city expands inland through urban planning transformation, it opens up growth potential in areas that are more accessible today than the coastal ones.

A practical guide when choosing. For buyers, understanding the infrastructure context of a location is an important tool for evaluating it. You should look not only at the property itself, but also at what projects are being implemented or planned nearby, and what the connectivity situation is like.

That is why, when choosing property, it is especially valuable to have specialists who monitor infrastructure development and understand how it affects different neighborhoods and the future value of properties.
