Inhabitat is showing photos of Stefano Boeri's wonderful Bosco Verticale, or vertical forest, being completed in Milan.
In 2011 it was the rendering that launched a thousand blog posts; the Financial Times called it "The most exciting new tower in the world."
It is a wonderful idea; like a tree planted in front of a house, they provide shade in summer, penetrating sunlight in winter, protection from wind, cleaning the air, producing oxygen and reducing noise pollution.
If they thrive. Last year I worried that the planters might be too small for the trees to really grow. Speaking with a landscape architect who preferred to remain anonymous, the concern was expressed that the planters couldn't possibly support this kind of growth. The trees would live, but they wouldn't grow very much. However, Liz Eve at Inhabitat writes that "Every plant has been chosen by botanists to thrive in it’s particular orientation and microclimate within the structure. Moreover, a specialized maintenance company will keep the vertical forest in good health in the years to come."
It will take a couple of years before we know if the building comes close to the rendering, but even if it doesn't, it's pretty spectacular. More images at Inhabitat.
