This 5-Story Apartment Building Is a Huge Urban Treehouse

There are 150 trees built into and around this building!

It's as close as you can come to living in an Ewok village in the middle of a city. Luciano Pia designed 25 Verde, an apartment building in Turin, Italy. It's designed so that the difference between inside and outside is blurred. There are 63 units in the 5-storey structure. The 150 trees provide shade and, the designer claims, help clean the air.
