The bandstand installed by Octavia Hill at Red Cross Garden is to be rebuilt thanks to £18,000 of Cleaner Greener Safer funding from Borough, Bankside and Walworth Community Council.
Plans to rebuild the bandstand were announced by Bankside Open Spaces Trust chairman Tim Wood during Friday's Mayfest at Red Cross Garden.
Around 300 people enjoyed music, dancing, crafts and sunshine during the annual May day event.
The new bandstand will be the latest stage in the restoration of the Victorian garden laid out by social housing and urban garden pioneer Octavia Hill.
"We understand that Octavia believed, as we still do, that having a bandstand was not just a place for bands to be, but a visible demonstration of a commitment towards music and performance," said BOST director Helen Firminger.
Last year BOST hosted a number of events to mark the centenary of Hill's death.
