"On the other hand it gives each bedroom a unique personality thanks to a colour range that achieves unity and uniqueness at the same time."
The 10 bedroom suites can accommodate 20 children, while the glazed base and basement provide a new entrance and offices respectively.
Ventilation ducts and underfloor heating means the temperature of each room can be kept stable, while vinyl siding and PVC flooring mean cleanliness is easier to maintain. Wide doors and 3.7-metre-tall ceilings are designed to be spacious enough for wheelchairs, stretchers and technical equipment.
A 200-square-metre roof garden sits above the dormitory to provide thermal and acoustic insulation, helping to reduce the building's energy consumption.
The Madrid firm, which was set up by Camino Alonso, Ignacio Lechón and Carlos Alonso in 1998, has a background in creating energy-efficient homes. The office previously converted a crumbling stone stable in a remote area in western Spain into a self-sufficient family home and also designed a cement-clad micro home that can be transported on the back of a flatbed lorry.
Cacti are displayed on plinths in the foundation's glazed lobby. Here, sections of carpet are wrapped around the white columns that support the ceiling slab, softening the effect of the raw concrete, glazing and strip-lighting.
"The ground floor consists of a glassed-in multipurpose hall for stimulation above which are small houses where the children sleep from which they can see, and be seen, " said the architect. "The intention is to highlight the presence of the building in its environment, becoming a feature in its area."
A glass and concrete cube at one end of the block provides a new entrance and a visitors' room, while a basement containing utility rooms and offices features large windows that opens onto a concrete-lined patio.
