A light self-supporting vegetated wall includes globally prismatic boxes, designed to be juxtaposed and/or stacked, the adjacent boxes being assembled together. Each box includes latticed or meshed surfaces, lined internally with a web, and filled with a cultivating substrate, such as humus. A network of water pipes and a network of air vents may be incorporated in the thickness of the structure, these networks passing through the parting lines between the boxes. The structure is designed for urban enhancement, as well as for producing noise screens, partition walls, hoardings and the like.
