The Metropol Parasol has displayed a new innovative way to use timber in construction. First of all, it is the largest wooden structure in the world. The building spans over 10,500 square meters, encasing 5,000 square meters and standing about 26 meters high. Not only that, but it also displays complex geometry rather than rectangular. This waffle-like timber structure serves as a canopy while also housing multiple bars and restaurants. The site called for a structure that would not ruin the historical grounds. Therefore, Roman and Moorish ruins discovered on site are displayed to the public on a floor underground and the structure itself only connects to the ground in a few locations. After many years of delay in construction, in order to accomplish these goals and make the structure stand, the timber and steel was bonded with high-performance polyurethane resin, a foam seal. This “glue” was tested to ensure it could withstand the highest possible temperatures. The structure stands on a concrete foundation with an interior of concrete, steel, and granite.
