The Twentieth Century Society has discovered plans to demolish Bradley House, a social housing block by Denys Lasdun in Bethnal Green, east London.
The building sits next to the recently renovated Keeling House, which is Grade II*-listed, and caseworker Cordula Zeidler told the AJ that the threatened block adds to its context.
The local council, the London Borough of Tower Hamlets, this week closed consultation on its demolition proposals, having won planning permission for a replacement scheme some years ago.
Zeidler - who was told of the demolition plans by a local campaign group - hit out at the council's proposals, arguing that the new scheme was simply 'short-termism' and a commitment to 'make a profit from the site'.
'A third building [Connet House] has already gone and it would be a real shame if the second is demolished, ' she said. 'What makes it worse is that the replacement scheme is awful.'
Keeling House was renovated in 2000 by the London-based practice Munkenbeck + Marshall Architects.
