Stefano Boeri, the Italian architect, famous for his Bosco Verticale, a group of tree-covered skyscrapers in Milan, introduced his new plans to pioneer a similar project in the Chinese city of Nanjing．

The Chinese version of Boeri’s Bosco Verticale, or vertical forest, will be his first project in Asia． The project will consist of two neighboring towers that will be coated with 23 different species of trees and more than 2,500 kinds of bushes hanging down the sides of the buildings． The structures will be built with the ability to house offices and will feature a 247-room luxury hotel, as well as a museum and even a green architecture school． The towers are currently under construction and are set for completion within the next year．

But two buildings aren’t enough for the ambitious Boeri as he now has even bolder plans for China to create “forest cities” in a country that has become known as an urban center choking on poisonous gases and dust．

In an interview about his plans to “greenify” the city and country Boeri said, “We have been asked to design an entire city where you don’t only have one tall building, but you have 100 or 200 buildings of different sizes, all with trees and plants on the sides.” Boeri continued, “We are working very seriously on designing all the different buildings．I think they will start to build at the end of this year．By 2020 we could imagine having the first forest city in China.”

Although these towers will lend a huge hand in decreasing air pollution in China’s eastern city, Boeri has said, it will take more than a pair of tree-covered skyscrapers to really solve China’s pollution crisis．This is why the Italian architect hopes to repeat his design in other parts of the country, as well as in other places around the world．
