The two proposed constructions (i.e., vertical garden and urban garden) are part of a relatively new eco-landscape concept. According to statistics, over 80% of this kind of buildings were created after 2007, and over 93% of the urban gardens were built after 2009. They can be built indoors as well as outdoors.

This concept is relatively new because although it was patented in the US in 1938, in Europe it has only started to become popular in the 1980s. The largest project of this kind, consisting of a wall covered with vegetation with an area of approximately 2700 square meters, can be found in Mexico.
