Brainchild of Italian architecture firm, Stefano Boeri Architetti, the Bosco Verticale(literally, “vertical forest” in English) is two residential apartment buildings peppered with cantilevered terraces. Each terrace is specially designed and engineered to support a small community of trees, shrubs, and other greenery.

When complete, Bosco Verticale will house 730 trees from three to six meters (10 to 20 feet) in height and irrigated primarily by the buildings’ grey water—runoff from baths, sinks, washing machines, and dishwashers. 5,000 shrubs and 11,000 plants will keep the trees company. A true forest.

Milan is the second biggest city in Italy and one of the most polluted in Europe. Bosco Verticale, an “anti-sprawl measure,” is intended to set a new course for the fashion capital. Vertical green spaces expand biodiversity without expanding city limits.

Trees and other green things filter dust and carbon dioxide and breathe out fresh oxygen. They’ll also produce humidity and shield residents from city noise. Along with all that, of course, they’ll bring a touch of nature into central Milan.
