Cities' Answer to Sprawl? Go Wild.
Urban forests, plant-festooned buildings and other ‘rewilding’ efforts can help bolster climate resilience, biodiversity, even moods
In a neighborhood of right-angled stone, stucco and brick buildings not far from Milan’s central train station, two thin towers stand out. Green and shaggy-edged, they look like they’re made of trees. In fact, they’re merely covered in trees — hundreds of them, growing up from the towers’ staggered balconies, along with 11,000 perennial and covering plants, and roughly 5,000 shrubs.
The greenery-festooned towers, called the Bosco Verticale, or Vertical Forest, are residential buildings in a broader-than-usual sense. The 18- and 26-story structures are “a home for trees that also houses humans and birds,” according to the website of architect Stefano Boeri, who has built tree-covered buildings elsewhere and is working on similar projects in Antwerp, Belgium, and Eindhoven in the Netherlands.
