@greg_harvey @pluralistic I've lived in areas like that, but they were at least reasonable about it. You could install double glazing, so long as it was in the style of the original sash windows. There's an little Georgian town near to where I live now, very restrictive, cannot replace windows in the old part of town at all, can only install internal secondary double glazing. Windows have to be maintained as they are and if replace, single glazed wooden windows. I don't have a problem with retaining the look of buildings, but this restrictive bollocks needs to fuck right off. Keep the style and construction of the windows for example, but allow double glazed glass to be installed. Before they introduced those restrictions in my old town... every old victorian terraced looked a mess with a hodge podge of mismatched and ugly cheap windows. They couldn't force you to change ones that were already changed, and placed no restrictions on the rear of the property. But new installs had to look victorian with modern materials.
