Green Cast is the name given to this plant-filled Japanese pharmacy and clinic. The building was designed by Japan's Kengo Kuma and Associates, and also contains an apartment and offices. The facade of the building is covered in aluminum panels, with the plants growing from between them. Green Cast's plants are nice to look at, but they also serve a more functional purpose. The plants are used to conceal the building's ventilation shafts and rainwater downpipes.

Japan's urban areas are notoriously cramped and devoid of greenery, so it's nice to see a building with a little bit of living color on it. This design also proves that plants can be incorporated into almost any urban structure. You just have to use your imagination sometimes.
