Clara Campoamor Library is a small facility with the programme requirements of a local library. It is located on a lot next to the Canal de la Infanta park, a green space that both separates and connects two neighbourhoods with very different realities. The building, on a single floor, is elevated above the ground to account for an important condition: the plot is crossed by a collector which, under exceptional circumstances, can overflow and cause flooding. The main entrance, from the square and from public transport, leads into an atrium that opens onto the different interior spaces and the facility’s central courtyard. From there, it descends in a series of steps to connect with the park, which sits on a lower level, passing under the building.
