A new gardening charity centre is being built in Battersea Park with a garden created by designer Sarah Price.
National charity Thrive commissioned architects Pedder and Scrampton to build the new facility to replace out of date portable structures.
The shape of the building is curved around the large London Plane tree that dominates the site and will have an open glass-walled Orangery on the inside.
The gardens surrounding the building will be planted by Thrive gardeners working to a plan created by Price, who won a competition to design the garden when still an up-and-coming designer.
Since she won she has designed a gold medal winning garden at RHS Chelsea Flower Show in 2012, was involved in creating the gardens at the Queen Elizabeth Olympic Park and worked with Thrive last year in the Old English Garden.
Thrive chief executive Kathryn Rossiter said the charity was looking forward to moving back to Battersea Park after being in New Covent Garden Market for two years.
"It will be fantastic for our gardeners and the extra space will allow us to help even more people.
"This will be a flagship building for us on East Carriage Drive which will also allow us to increase the number and variety of plants and herbs we can use and sell to members of the public."
Wandsworth Council’s cabinet member for environment and culture councillor Jonathan Cook said the council was happy to help Thrive.
"They have helped thousands of people with disabilities over the years and long may that continue."
Thrive uses gardening to enable people with disabilities and mental ill health to transform their lives.
