The towers, called the Bosco Verticale, are under construction in the city of Milan .
Towering over the city skyline, these are the world's first forest in the sky apartments.
With trees equal to one hectare of forest spanning 27 floors, these 365 and 260-foot emerald, twin towers will be home to an astonishing 730 trees, 5,000 shrubs and 11,000 ground plants.
Michele Brunello, 35,director of Boeri Studios, explained “The idea for a vertical forest came when we were involved in a local tree planting project.”
“We imaged a building that allowed the landscape to enter it. By creating a tower that truly becomes a home for the landscape we have a powerful tool.”
Brunello's concept is designed to save on land, which, he said, is a precious resource in the centre of a major city.
“We can provide the quality of life of expensive housing without consuming the resources that conventional housing would demand. On top of this we have a building that is a world symbol for sustainable living.”
Bosco Verticale has been designed as a home to a variety of plant life, which planners hope will act as a filter to pollution from traffic, shade people from the Mediterranean sun and will change its appearance each season.
Apartments range in price from £560,000 for a low level 80 square meter apartment to £1.7 million for a 200 square meter penthouse with commanding views of the city.
