Last week there was a visit to the excellent Lagos, Peckham, Repeat exhibition at the South London Gallery. It is housed in the John Passmore Edwards building (1893) and the marvellous Fire Station annexe, which was created in 2018 in the former Peckham Road Fire Station (1867, above in 1905). So this week on the Post we look at arts organisations which are in interesting buildings saved from demolition by clever, creative, and thoughtful owners and architects.
