The garden aims to improve air quality in the area, whilst providing a tranquil oasis for visitors, workers and those passing through. Kate Gould, the designer of the garden and five-time Chelsea gold medalist, specifically chose certain plants in the garden for their contribution to air purification. The ferns and plants have been specifically chosen to help remove pollution, and include acers, Chinese dogwood trees and seven-son flower trees, all believed to have a beneficial impact on air purity. Lightweight trees will provide shelter and seclusion from the bustling urban surroundings, with vibrant low-level plantings beckoning in visitors off the street.

Kate Gould stated, “Many of the gardens I have put on the show ground at Chelsea have been related to this theme [of providing a public space and improve air quality] as I feel it is imperative to create healthier spaces for people living in an frequenting the city. I hope the garden thrives, is well used, and helps to improve the air quality for visitors and residents of the West End for the time it will be spending in this space.”

Simon Loomes, the strategic projects director of The Portman Estate, said: “For us it is a first step which, if successful, will see the creation of a number of more permanent pocket parks across the district. Our estate sits between Regent’s Park and Hyde Park and these new sites will help create ecological corridors allowing wildlife to migrate and benefit from a wider green network.”
