The £700,000 job at the new City Inn hotel site near the Tower of London will begin later this month.
Frosts Landscape Construction is using a modular living wall system planted by Aldingbourne Nurseries to create the wall, which will stretch up 10 storeys before wrapping around the building between the 10th and 12th floors.
Around seven to 10 staff from Frosts will work on the project, starting at the end of April. The first phase will take around two to three weeks, explained Frosts landscape construction director Aidan Lane. The team will then return in July for another three to four weeks to finish the project.
"It is the biggest living wall we've done to date," Lane told HW. "It will be the largest living wall in London on a building."
However, it will not be quite as large as the 1,400sq m wall at Westfield shopping centre in Shepherds Bush, although that is freestanding rather than attached to a building.
"This will be a fantastic scheme," added Lane. "Living walls are becoming more popular, but they are expensive. The key is water - there needs to be a regular supply."
