This might just be the coolest most organic building to ever be built within an urban area. We've covered some pretty amazing treehouse's before, but they have all shared something in common - they are located somewhere deep in the countryside or wilderness.
This building however, designed by Luciano Pia, an architect in Italy, imagines what a treehouse might look like if it was right in the middle of a thriving city, such as Turin, Italy.
The 5-story-high structure is a mixture of trees, wood and steel that lets those lucky enough to live inside feel as if they were in a tropical rainforest. In total there are 150 trees that surround the building, absorbing sound pollution as well as keeping the air cleaner. This is one building we would love to live in!
