The owners of a development site on Tower Bridge Road - where work began 16 years ago and has never been completed - say they have held early talks with council planners about a 32-storey tower proposal.
This summer Southwark Council's planning committee approved plans by First Base and Starwood Capital to strip the unfinished buildings at 151-157 Tower Bridge Road back to their concrete frames and re-clad them.
Now the site is up for sale with a £60 million price tag and the suggestion that a "landmark" 32-storey tower could be built as a "gateway" to SE1 from Tower Bridge.
After Southwark approved further plans in 2009, construction ceased in 2010 when the developers went bust.
Starwood Capital and First Base bought the plot in 2015 and appointed architects Arney Fender Katsalidis to draw up plans to complete and enhance the scheme.
In May this year those plans were approved by Southwark councillors.
However, the sales blurb for the site says that "informal discussions / pre-application advice has been sought with Southwark regarding a tower option on the existing site to create a landmark 32 storey structure providing a gateway scheme entering from Tower Bridge into SE1".
