The restored artworks by post-war artist William Mitchell were unveiled at Foxborough Gardens Estate as part of his centenary year.
The murals, located inside the entrances of the two tower blocks, were saved by the Heritage of London Trust (HOLT) working with local people.
Dr Nicola Stacey, director of HOLT, said: “So much of London’s 1950s and 1960s public art is now under threat or neglected.
“We’re thrilled to have been able to help rescue and restore these murals.
These are the fourth and fifth LCC Patronage of the Arts projects we have completed in under two years and we have four more coming up shortly.
“We look forward to a burgeoning interest in London’s wonderfully eclectic post-war art.”
Involving more than 240 young people through HOLT’s Proud Places youth engagement programme, the project introduced participants to conservation techniques.
Children from Beecroft Garden Primary School helped paint the concrete mural during their visit and also attended the unveiling ceremony.
Speeches were made by Dr Stacey, Lewisham councillor Jacqueline Paschoud, tenants’ association chairman John Keidan, and Beecroft Garden Primary School’s head boy and head girl.
The ribbons were cut by councillor Paschoud, Elliot and Ranielle.
One mural, made from wood offcuts and furniture fragments, depicts birds, fountains, castles, and sunbursts.
The other is a brightly painted abstract concrete relief.
Mr Keidan, chairman of the Foxborough Gardens Tenants and Residents Association, said: “This has been a wonderful project, we have put in a lot of effort to help make this happen and it’s been a real success.
“You can really see the difference it makes to have these murals looking so vibrant again.”
The wooden mural was removed, sanded, and losses were filled with newly cut pieces of wood, using molds from the original shapes.
The concrete piece was cleaned, stripped of old paint, and repainted with UV-resistant cement paint.
Restoration was carried out by Temple Studios and Taylor Pearce Ltd.
William Mitchell’s public works are found across the UK and include the doors of Liverpool’s Metropolitan Cathedral and the Egyptian Staircase at Harrods.
The project was made possible with funding from the Heritage of London Trust and the Pilgrim Trust, and was nominated by the Foxborough Gardens Tenants and Residents Association.
