The world’s first vertical forest is rising in Milan. The Bosco Verticale, the project’s official title, will be completed later this year, marking a significant step in development of green architecture. The plan consists of two apartment towers festooned with a series of concrete decks, staggered and offset from each other to give the structures their Jenga-like appearance. Once completed, nearly 2.5 acres of “forest” will have been planted in these balconies. Incredible!
