I've re read the document and now it seems a bit ambiguous ; does anyone else think re the reference to article 4 and discussion on reinstatement of ie sash windows, this is saying that they will make people change back, or is it saying that if people apply to change their windows then sashes which resemble the originals will be encouraged. I can't see the point of the latter to be honest as it would be self evident so my take on this is that it is indeed talking about getting people to reinstate stuff. Any opinions welcome! Could be that its just badly worded.
