Vertical Garden Lives on Building's Wall

That garden was installed on the exterior of a new children's library in San Vicente de Raspeig, Sapin.
It uses cubic containers filled with substrate felt confined between two metal grids, one outdoor and one indoor. Containers are accessible from corridors located in the rear, where they can be replaced. The irrigation is possible by a metal structure built upon the deposit of concrete.
A lot of different types of flowers and herbs fill in the top layers of the garden. There is also a suspended scaffold in front that allows for pruning and replacing specific species.
