Angry residents have condemned 'a mistake' by the Crown Estate that threatens a conservation area in Hackney.
Conservation campaigners last week hit out over the inadvertent destruction of Victorian windows in a property last year, and deemed their replacement with double glazing as 'the thin end of an insidious wedge'.
The local authority granted post-hoc planning permission for the gaffe after Victorian sash windows were replaced by modern double-glazed windows at 104 Gore Road in east London.
In a letter to Hackney council's head of planning, Sue Foster, the angry residents wrote: 'In the event your actions have authorised the fitting in a conservation area of modern pastiche to a single property in the middle of a Victorian terrace - where all the other properties have had their original windows repaired and repainted.'
In correspondence seen by the AJ, Hackney councillor Muriel Purkiss said: 'A meeting of the Crown Residents' Association on 20 May 2004 was attended by Ross Houston, area manager of the Crown Estate, and Giles Clarke, head of residential Estates at the Crown Estate.
'Both these officers confirmed the facts in the foregoing paragraph and that the modern windows had been used 'by mistake', ' she added.
