The project takes advantage of the own inclination of the structure to turn it into an artificial mountainsides. Hanging the new vegetation of the concrete porticos, the mechanism includes three different levels: the exterior landscape, continously interconnected to the interior by the prefabricated framing and grandstands which were not discarded; the two-layer bags, the metal bags that contain individually the roots of each tree and it arids, and the fiber bags that receive the drained water of group of trees; and the lowest level at the street, were the water from above is carried by canals to the pumps.

Before, a stadium with future of demolition. Now, a double-vision of vegetative bags at 30 meter high. A general system which could be used in more cases in order to recycle and provides the revolution of nature.
