Hi there - having an old house within a conservation area would normally mean that I'd have to fit nice wooden sash windows, but, some previous owner has fitted UPVc everywhere in modern styles. I now wish to replace and re-size openings back to typical sash type but think it will be hugely expensive to fit timber. Due to planning rules I can go with what is in already and use UPVc again - this would be far cheaper I think so a happy medium would be to get some kind of replica of old but new materials - does this sound crazy ? or can this sort of window be found? any thoughts or recomendations would be welcome
