Gregory Polletta and Sung Jang of iGNITIATE have designed Topiade, an "overlay facade," for existing Louis Vuitton stores.

It appears to be a new kind of intermixing of living walls with topiary. This is wonderful because everything Louis Vuitton does gets knocked off instantly.

Soon all of Canal Street in New York, Spadina Avenue in Toronto, countless cheap shopping streets around the world will sport green living facades.
