A new initiative has been launched to get more people involved in their local communities. To get the campaign underway, 24 charity projects across London are being transformed in less than 24 hours, with one being to change an disused rooftop space into a children's playground.
With hundreds of volunteers, it's a battle against the clock to show how much change can be made through a series of small actions. The aim is for the impact of the projects to leave a lasting effect and inspire people all over the country to get involved with their own communities.
Actress, Joanna Lumley was there to help launch the campaign and said: "This is huge. This is building a new kid's playground on top of a block of flats."
Working with the event, CEO of Marks and Spencer, Marc Bolland said he wanted to "spark something good" and believes these projects "will improve the communities".
