Patrick Blanc's green walls in London

 

His latest work is at the Atenaeum hotel in Picadilly. Construct Ireland previously mentioned some of Blanc's work here.

Journalist Stuart Jeffries explains how the walls are constructed:

[Blanc] attaches a metal frame supporting a PVC plate to a wall, then staples on layers of polyamide felt that support plant roots. His magical living walls thus have no need for soil. Watering and fertilisation are done automatically through pipe networks working on a closed circuit. He chooses plants according to available light and their ability to grow in particular conditions. He creates vertical gardens both outdoors and indoors (often using artificial lighting for the latter).
