Curiously enough, here in Spain they're still pretty common nowadays, as lots of houses purposely incorporated green awnings, both to protect an exponentially-growing number of these houses from harsh sunlight during summer season, and to presumably 'soften' the arrival to the city of an increasing quantity of newcomers from rural Spain, as they already were very familiarized with them and, the designers thought, would find spots of green on the building more appealing comming from a greener countryside.
