Help please! This saga started when we decided we'd get a new front door, the fitter came along, started work and it quickly became apparent that the 30yr old single storey extension which it leads into was in a fairly poor state structurally and needs to be replaced.
The question is, can we just knock it down & replace it or do we need planning permission? We've managed to find a builder who has a good reputation who is satisfied that, as we're doing a like for like replacement (other than the door & window which we were already changing), we can just go ahead. We're sticking to the original plans (well, plus foundations and steels), original footprint and the same materials. That seems to make sense to me but all of the guidance I can find about permitted developments is all about new extensions & changes, not replacing existing one or about porches and, whilst we call this the porch, it's more substantial than that.
