Eco-friendly, sustainable, solar powered and so on are just a few and probably the most common features of an eco-friendly architecture. However, the Vertical Park is entirely different and I must say it stands out amongst them. Being an eco-friendly stackable skyscraper is new to me. It might be existing way back then but I must admit this is the first time I have heard about it. Designed by Jorge Hernandez de la Garza for Mexico, the vertical park is made up of a series of stacking units, a solar powered one, houses sky-gardens and recycles all of its own water. Amazing!
