Quite futuristic, I find...
I think this is an 11-storey residential building. It must actually be the largest so called vertical garden in the world for now.
The Colombian capital city seriously lacks greenery. Only 4 m2 per dweller, if I recall correctly.
So this would be an effective solution (among others) to this problem.
