The Bermondsey building is being redeveloped by Vantage, a joint venture London partnership between Legal & General Capital and PGGM.
London architect SPPARC hs designed the scheme, which will see a seven-storey modern office block oversail the retained three-storey Victorian warehouse.
Work is due to start on site during 2019.
Nigel Fuller, Senior Fund Manager at Legal & General, said: “The redevelopment of 47 Tanner Street will be a strong example of how we can transform existing buildings in prime urban locations into much needed modern office space.
“There is a huge demand for this type of office space from occupiers who recognise the importance of their work environment to improve their staff’s well-being and productivity.”
Trevor Morriss, Principal at SPPARC said: “Our proposed scheme is characterised by the oversailing additions being brought to the street in an angled brick prow.”
