The Spanish Pavilion for the Brussels Exhibition was developed by the Spanish architects Corrales and Vazquez Molezun in 1958, after winning the competition for that.

The building was asked to be flexible and re-usable after the exhibition in Brussels and so it was. Nowadays it is displayed in Madrid. The project is solved using hexagonal structures as a repetition. The project itself is melt with the surroundings adapting to the trees and changes in the terrain.

The lighting, structure and constructive problems are solved at once using the same module. In the end the project grows in a light and natural way. It is made out of 130 structural hexagonal modules (2.95 m length and heights between 3.5 and 9 m. All the envelope is solved using a 'screen-like' skin with wraps the irregular shape of the floor plan.
