The strong and convincing vision of this project consists of creating a large green island on an empty piece of land at the interface of three mainly residential districts in Madrid in order to achieve a considerable improvement of the climatic conditions. Usually such projects are not feasible due to the extremely high cost of land in urban centers. The striking idea of the project is to combine the positive effects of huge plantations on health, air and water quality with the economic potential of the industrialized production of trees and pot plants for private and public use. The open plantations and the greenhouses will be designed as a public park and enriched with a multitude of cultural, sports, health and educational facilities.
