Would I be able to buy one (preferably cheaply and do it up) and hang it within the frame that's already there?
It's currently a puvc or whatever door with a skinny tall window next to it all in one iyswim - I want to just replace the door with something nice for now and rethink when we've saved enough to redo the double glazing.
Can I buy a wooden door and hang it on the plastic?
If I wanted a wooden door and that isn't an option, what would I need to do?
