vertical greenery

"Architects and developers continue to inject greenery into high-rise buildings as the concept becomes far more common.

Beyond adding greenery to balconies, roof terraces or on the walls of skyscrapers, however, there is also a trend toward using building surfaces for urban agriculture as rapid urbanisation creates demand for affordable inner-city housing and accessible food.
