A pair of skyscrapers by Milan office Boeri Studio are nearing completion in the Italian city, featuring as many trees as could be planted in a hectare of forest.   The first project born from this concept is now nearing completion in the Isola area of Milan’s fast-developing Porta Nuova district. Two towers, measuring 80 and 112 metres, are set to open later this year and are already home to 900 trees.

A mixture of large and small trees have been planted on balconies on all four sides of the towers, accompanied by 5,000 shrubs and 11,000 floral plants. The design team claim these will absorb dust in the air, helping to depollute the city.
