Two high rise residential tower blocks in Milan, where trees and humans coexist

Milan’s Bosco Verticale (Vertical Forest) is a new approach to high-rise buildings in which trees and humans coexist. Bosco Verticale is an architectural concept which replaces traditional materials on urban surfaces using the changing polychromy of leaves for its walls. The project consists of two towers of 80m and 112m, planted with almost 17,000 trees, shrubs and plants. This provides the equivalent greenery – over an urban surface of 1,500m² – of 20,000m² of forest and undergrowth.

Bosco Verticale increases biodiversity by promoting the formation of an urban ecosystem where various plant types create a distinct vertical environment. The diversity of plants creates a microclimate, which produces humidity, absorbs CO2 and particles, produces oxygen and protects against solar radiation and noise pollution. The choice of species and their distribution according to the orientation and height of the facades is the result of three years of studies carried out by the practice alongside a group of botanists and ethologists. The green facades will help boost the city’s flora and fauna, with an initial estimate that 1,600 birds and butterflies will find homes there.

The biological architect rejects a narrow technological and mechanical approach to environmental sustainability. Bosco Verticale is a model of vertical densification of nature within the city. This is an approach to metropolitan reforestation that contributes to the regeneration of the environment and urban biodiversity without expanding the territory of the city.
