Jolly good: another green living wall is being installed in London and TreeHugger has the first shots of it.

Located at a busy, noisy and ugly intersection in downtown London, the new vertical garden, which is 180 sq. metres in size, will cover one side of the Edgware Road Tube station.

Last week the finishing touches were added, in time for its unveiling this week.

Workmen from Biotecture, the company installing it, were just putting in the last plants. It is planted with a mixture of evergreen and perennial plants selected to survive in a roadside environment, plus trap dirt particles.

Biotecture will experiment with a variety of plants having smaller leaves and different textures and growth habits to understand their ability to trap small particles. Plants in the wall include Munsted lavender, geraniums, lamb's ears, heuchera and veronica.

Plants will be grown in a hydroponic, soil free substrate and the structure that supports the plants includes a waterproof backing called Ecosheet -- which is manufactured in the UK from recycled materials.

Here are the main characteristics of the system:

Independent units of 600mm x 445mm
Units irrigated by 4 drippers at 150mm spacing
Construction cost: £600 - £800 per m2
Hydroponic system
Integrated design enables moisture control to reduce water consumption
Includes sun resistant plants such as lavender, geranium and Stachys
Modular system which allows quick construction
The wall panels comprise horticultural rockwool manufactured by Grodan within a regenerated plastic case
Each panel has capillary breaks for water descent control

The wall will be monitored every week for dirt particle absorption from the traffic emissions. It is drip-fed twice a day. Using a SIM card, the Biotecture offices can monitor the irrigation from an off-site location.

The wall is part of a series of green measures the city is introducing in order to reduce pollution from traffic emissions.

The government has given Transport for London a grant from a new Clean Air Fund specifically designed to help London comply with legally binding European targets for reducing pollution.

In addition, there are plans for approximately 500 new street trees and shrubs to be planted at busy intersections.
