The shop had been derelict for a long time and the Council eventually intervened, repairing the roof and seeking costs from the owners. That prompted speculation in January that the property could be put up for auction. We're not sure what happened after that - if you know, please tell us.
UPDATE: TM has pointed us to the planning application, which was for:
The demolition of the existing extension and construction of a single storey extension to the rear of 63 Loampit Hill SE13, together with an extension to the rear roof slope, installation of roof lights to the front and side roof slopes, elevational alterations to the rear and new shop front to facilitate conversion of the property to provide a shop (Use Class A1) and 1 one bedroom self-contained flat on the ground floor, 1 one bedroom self-contained flat on the first floor and a self-contained studio flat on the second floor.
As TM says, this means the retail floor space has been significantly reduced, which will limit the shop's versatility when the unit is finished.
