I’ll take three, please. Construction has already started on a pair pf buildings in Milan, Italy that incorporate massive planters on the outside of the building which will give homes to about 900 trees and shrubs. This vertical forrest is supposed to help air quality in Milan.
Interesting to see such a lofty, concepty project enter the actual building stage. However, I think the real trick will be to actually correctly cultivate the plants when the building is completed. In my experience working with Friend of the Highline on the NYC Highline project, I noticed that the final element that was the hardest to fully realize was getting the mix of plants just right to fulfill the architects vision, and to actually work in a sustainable manner.
