From housing to schools, from museums to infrastructure: exposed concrete is also part of Marti's DNA. Discover with #ExposedConcrete a selection of our projects where technical precision meets architectural ambition.
The new buildings are an addition to the existing school premises, which comprise an old, listed building and three buildings from the 1970s. The buildings' supporting structures are made of reinforced concrete. Thanks to a complex system of shear walls, a large part of the building's load is cantilevered, creating a roughly 8-metre-wide covered schoolyard along the entire length of the building. Inside, the cascading staircases immediately catch the eye, with steps finished identically to the walls and ceilings. The latter incorporate sound-absorbing elements with a harmonious colour gradient. The layout preserves generous circulation spaces between old and new buildings, creating an environment conducive to learning and social interaction.
