The Swimming Centre completes a municipal sports facility composed of low quality constructions meshed by the passage of time, The unit, set north-east of the urban zone, is developed along Pine Promenade near the Henares River. Using an elementary working scheme, the Centre is organised in a linear structure, arranging its compositive elements in succession: link vestibule, changing rooms and amenities core, instruction vessel and multipurpose vessel.
The new construction materialises externally like a great basket composed of prefab concrete girders, set parallel to the Pine Promenade, linking the entrance to the three buildings of the sports c6mplex at the northern end of the new construction by means of a small porch that leads onto a common foyer.
Due to the proximity of the water table, the building is raised above ground level. The Swimming Centre is on the first floor, leaving the ground floor of the new building for storage and facilities. This solution mitigates the problems caused by the proximity of the Henares River, and makes the main hall predominate over the degraded surroundings while providing a clearer vision towards the horizon and the nearby mass of trees from inside,
The basket of prefab beams blurs the edge of the construction: by day, the hall and the lobby receive sunlight through the filter on the facade while at night, the building looks like an illuminated beacon, a waning reference point for people strolling along Pine Promenade.
