Bosco Verticale will be the World's First Vertical Forest (Milan, Italy)

A forest in the form of a skyscraper  (Milan, Italy). Each apartment has a balcony with its own little mini-forest. These provide the pollution-filtering benefits of plant life and the energy-saving benefits of shade, but in a small area.

The Bosco Verticale is a system that optimizes, recuperates, and produces energy. Covered in plant life, the building aids in balancing the microclimate and in filtering the dust particles contained in the urban environment (Milan is one of the most polluted cities in Europe). The diversity of the plants and their characteristics produce humidity, absorb CO₂ and dust particles, producing oxygen and protect the building from radiation and acoustic pollution. This not only improves the quality of living spaces, but gives way to dramatic energy savings year round.

Each apartment in the building will have a balcony planted with trees that are able to respond to the city’s weather — shade will be provided within the summer, while also filtering city pollution; and in the winter the bare trees will allow sunlight to permeate through the spaces. Plant irrigation will be supported through the filtering and reuse of the grey water produced by the building. Additionally, Aeolian and photovoltaic energy systems will further promote the tower’s self-sufficiency.

The design of the Bosco Verticale is a response to both urban sprawl and the disappearance of nature from our lives and on the landscape. The architect notes that if the units were to be constructed unshackled as stand-alone units across a single surface, the project would require 50,000 square meters of land, and 10,000 square meters of woodland. Bosco Verticale is the first offer in his proposed BioMilano, which envisions a green belt created around the city to incorporate 60 abandoned farms on the outskirts of the city to be revitalized for community use.
