I’ve been hearing about this for awhile and it is finally under construction!!
Excerpt:
The Bosco Verticale is a new superstructure designed to bring the world’s first vertical forest to Milan, Italy. While many were skeptical when it came to the feasibility of construction, Boeri Studio reports that the structure is certainly more than just a fantasy — in fact it’s well on its way to being completed this year. The project’s two towers have already reached full height, and since April of 2012 teams have been installing trees on the structure. Though construction has slowed due to rain and snowfall in Milan over the last couple months, things are anticipated to kick up again very soon to meet the late 2013 opening.
Milan is one of the most polluted cities in the world – the Bosco Verticale project aims to mitigate some of the environmental damage that has been inflicted upon the city by urbanization.
The two towers measure 260 feet and 367 feet tall respectively, and together they have the capacity to hold 480 big and medium size trees, 250 small size trees, 11,000 ground-cover plants and 5,000 shrubs (that’s the equivalent of 2.5 acres of forest). The types of trees were chosen based on where they would be positioned on the buildings’ facades and it took over two years of working with botanists to decide which trees would be most appropriate for the buildings and the climate. The plants used in the project were grown specifically for the building, pre-cultivated so that they would gradually acclimate to the conditions they would experience once placed on the building.
