The project will use 1,110 trees, 2,500 shrubs, and a total 23 local tree species.
With little space for cultivating plants on a large scale in the Chinese city of Nanjing, this architect has a plan to help an urban garden grow up—literally. By 2018, Italian architect Stefano Boeri will complete his vertical forest installation upon the Nanjing Towers, a pair of skyscrapers each looming 656 feet and 354 feet above the city.
The project will use 1,110 trees, 2,500 shrubs, and a total 23 local tree species, to cover the facade of the two buildings and help revitalize the region's ecology. "Vertical Forest is a model for a sustainable residential building, a project for metropolitan reforestation that contributes to the regeneration of the environment and urban biodiversity without the implication of expanding the city upon the territory," Boeri wrote on his website, discussing the concept of Vertical Forest in general.
The Vertical Forest can also be colonized by birds and insects, helping to reinvigorate the city's vegetation and animal life, he added, which will lend itself to improving the city's other environmental corridors, like parks or gardens. The project will also contribute to a micro climate and will filter dust particles in the urban environment. As Boeri wrote: "The diversity of the plants helps to create humidity, and absorb CO2 and dust, produces oxygen, protects people and houses from the sun's rays and from acoustic pollution."
