Sir Terence Conran has been granted the honorary freedom of the Borough of Southwark in recognition of his role in the regeneration of Butler's Wharf at Shad Thames.
The commemorative scroll was collected by Sebastian Conran on behalf of his father.
The citation for Sir Terence's award, delivered by Michael Cleere, included these words: "His pioneering role in the regeneration of the north of Southwark has demonstrated that regeneration can involve the refurbishment and renewal of existing buildings as well as demolition and rebuild.
"His vision for the north of this borough has inspired businesses and residents alike."
Sir Terence is also the founder of the Albion restaurant group which has a branch at Neo Bankside.
The famous designer was one of four recipients of the freedom of the borough on Saturday.
Also honoured were past mayor Sam King MBE, actress and Camberwell resident Jenny Agutter and the Camberwell squadron of the Air Training Corps.
The Freedom of the London Borough of Southwark was last awarded in 2012.
