24/07/2025

SANJOSE Constructora has been selected to carry out the construction of the largest wave park in Europe, Gemswell Surf Madrid, promoted by Stoneweg InfraSports (a joint venture between Stoneweg and Teras Capital) and Atlético de Madrid. The project will be located in the upcoming Atlético de Madrid Sports City, adjacent to the Metropolitano Stadium in the San Blas–Canillejas district of Madrid.

The construction works for Gemswell Surf Madrid, an ambitious project by Stoneweg InfraSports with an investment of over 50 million euros, will begin immediately and are expected to be completed by the last quarter of 2026.

Once the earthworks and compaction of the land have been completed, the foundation of the building that will house the surf academy, the surf shop of more than 400m², and several food service points will begin.

Later, in October of this year, the foundation of the lagoon platform will begin so that in April 2026 the wave generation machine can be installed, which will feature the technology of the Spanish company Wavegarden. It is estimated that the lagoon will begin to be filled in November of next year.

The surf lagoon, which will be the largest in Europe, will have a surface area of 23,000 m² and a maximum depth of 2.85 meters. Visitors will be able to enjoy more than 20 types of waves up to two meters high, with up to 120 people surfing in 60-minute sessions.

Gemswell Surf Madrid will also feature a 700 m² skate park to perfect surf techniques and other related activities. The facilities will include five food service points, amounting to approximately 3,000 m² dedicated to gastronomy, with beachfront terraces. Each restaurant will offer a concept aimed at different audiences and inspired by iconic surf destinations.

Stoneweg InfraSports forecasts that Gemswell Surf Madrid, which will operate year-round, will receive around 500,000 visitors annually, in addition to creating more than one hundred direct jobs, with the goal of positioning Madrid as one of the leading surf capitals of the world.

Regarding sustainability, Gemswell will integrate different strategies to minimize environmental impact through sustainability solutions that range from space design to operational aspects. The park is designed under the requirements of BREEAM Very Good, an international environmental sustainability certification, thus prioritizing the reduction of the environmental footprint throughout the complex’s life cycle. In addition, it includes renewable energy systems, such as solar panels, and an architectural design that optimizes natural light, minimizing electricity consumption. Water management is also a fundamental pillar: it features solutions such as rainwater reuse and efficient irrigation systems.
