UK company Biotecture have created a green wall for the side of Edgware Road Underground station in London which sits near the busy, and very polluted, Marylebone Road. It is hoped that the new wall will help eradicate some of the air pollution in the area.
Buildings with green walls are popping up all over the UK thanks to companies like Biotecture. This one is on a library in the town of Grimsby in northeast England.
Green wall pioneer, Patrick Blanc created this flourishing facade for the Musee du quai Branly, Paris in 2005.
He also oversaw the creation of a vetical garden on the side of the CaxiaForum, Madrid in 2007.
The WestBlaak Building (bottom left) in Rotterdam was recently fitted with a green facade which its developers, Rotterdam Climate Intiative, hope will cover large sections of the car park. It has also been created to aid water management and reduce CO2.
