The Rey Juan Carlos Hospital is located to the north of the Madrid town of Móstoles, bordered by the Extremadura highway, a university and the back street of a low-density residential area. The area of the whole complex is about 95,000 square meters, is composed of several mayor elements: a large prismatic horizontal lower volume that hosts the sanitary areas with two ovoid crown towers, visible from the highway. This are the hospitalisation rooms that with its superior elevated position and an interesting abstract design of their facades, which employees translucent pieces of curved modulated glass, that have become landmarks easily identified from the highway which runs by it, and gives access to the complex from distant parts of the whole city. A clean and light architectural composition in alignment with the ideals in health systems, of minimal white and clean spaces that invites to light and quiet well being, and contemplation. A singular, very different project for its typology, however now a building reference not only in the Spanish Health Sector, but also at an international level.
