In Turin (Italy) a new house took root (literally): it is called 25 Verde and it is a forest-building. Designed by Luciano Pia, the five-level building resembles a giant tree and its 63 flats seem burrows into the bark. The structure contains 150 tall trees and 50 smaller plants that, every hour, produce around 150 thousand liters of oxygen and absorbe 200 thousand litersof CO2 and fine particulate.
It is a giant green lung. In addition to the benefits presented above it is useful to remember that plants are able to keep under control the temperature and the strips of wood that cover the terraces are able to filter the sun's rays in summer and let the sunlight pass during winter. Nature and urban environment seem to coexist in a green building project.
