Southwark Council's planning committee has approved proposals for a new library as part of the £11 million regeneration of Camberwell.
The building, set to be constructed in front of the Magistrates Court on D’Eynsford Road, will boast meeting rooms, study areas and public-access computers in addition to ground-floor books sections for adults and children.
Councillor Veronica Ward, Soutwark’s culture lead, said the approval marked a milestone for the area.
"We currently have a very poor library service in Camberwell so this granting of planning permission is a big step forward,” she said.
“Not only does it give the go ahead for a new, much needed library but it helps to realise our ambition of regenerating Camberwell and its surrounding areas."
The planning permission for the new library also includes repaving the area, tree planting, the creation of new outdoor seating, and improvements to local lighting.
"We've already surpassed one degree of global warming," said Kristen Buida, manager of the London Climate Change Partnership.
