Walls in cities deliver an huge amount of space. Mostly this kind of space is very often unused. Vertical Gardening could be an approach for making this kind of space used for a more sustainable city infrastructure. In my installation I focused on walls, which are close to canals and rivers.
Vertical Gardening approaches with lifting functionality.
