St Clement Danes
St Clement Danes is in the heart of the city, by Covent Garden, making the roof top playground an air pollution hot spot. Ivy green screens and planters were installed around the perimeter of the playground, helping to improve air quality, privacy, and add greenery to the playground (turning the grey green).
Before the installation the school had no minimal to no greenery, making the planters and green screens have a dramatic difference.
