The idea of this preschool was to evoke a forest. In a newly developed part of Orense’s university campus, the building for use and accessibility reasons is one-story, and it is built with the structural economy of vernacular architecture. Four screens of reinforced concrete – with basic services imbedded in them – support two slabs of the same material, which is also used for floors and ceilings. Completed with a wall of blocks of lightened clay 19 centimeters thick, the complex is clad with a lattice of cedarwood treated with lasurs for greater durability, painted green. The design and the choice of wood address requirements that are aesthetic, mechanical, and climate-related: to give unity to the complex, lighten the load in the structural cantilevers, and combat the local climate – with its temperature leaps of up to 40 ºC between summer and winter –, improving protection against the sun’s rays and creating the conditions for cross ventilation.
