A wall or facade covered with plants. It can be a facade of climbers growing from the ground on cables or mesh, or a living wall with substrate and irrigation on the vertical face itself.

What it solves

It shades the wall and keeps it cooler, so less heat gets inside. It offers food, shelter and nesting places to birds and insects in cities where almost no open ground is left.

Today

Choose native climbers planted in deep soil at the foot of the wall, with cables or mesh set away from it. If you choose a living wall with substrate, plan the irrigation, drainage, access for pruning and who will look after it every month.

Common mistake

Installing an eye-catching vertical garden without an irrigation plan or a maintenance budget, which dries up in a few months and is left as an empty structure.

Tomorrow

In hot neighborhoods, boundary walls and blank facades can become green corridors for birds, bees and butterflies, cared for by neighbors. Watering them with rainwater or treated gray water saves the drinking water they use today.

Fact Thanks to transpiration, the leaf surface does not rise more than 4 to 5 °C above air temperature. Sometimes it stays below it.

Where it comes from

  • 1University landscape architecture Urbana, Illinois, United States, 1938
    A landscape architecture professor patented a planted wall system, which never went beyond prototypes in his backyard.
  • 2Contemporary vertical garden City of Science and Industry, Paris, 1986
    A botanist, an architect and an engineer achieved there the first large indoor living wall that worked successfully.
  • 3Study of urban birds Staffordshire, England, 2010 and 2011
    On 27 walls with climbers, birds nested, fed and took shelter, while on 27 bare walls they were never seen.

Masters

  • Geoffrey Bawa Kandalama Hotel, Dambulla, Sri Lanka, 1994
    He designed a long building resting on the rock, with a green roof and facades that the jungle gradually covered with climbers. The vegetation shades the rooms and blends the building with the forest.
