Sorry, it's a bit complicated! So we have just finished our loft conversion. It was a long process getting PP because it was a joint application with our neighbour and required a legal agreement ( we are a pair of semis and needed to raise the ridge height to get a decent head height). After nearly a year we finally, got permission. EXCEPT there were some conditions on the PP. We had to submit a building schedule outlining stages of the work which then had to be approved, which might take weeks. Given that our builders were booked in and the conditions had never been mentioned during all our many conversations with planning, I spoke to our neighbour and he said he was going to ignore them, as we were doing it at the same time anyway and didn't want to hold things up. He was going to use the same builders. So builders started on our house. We then found out from them (not him), that he wasn't going to use our builders, but do it himself, with a mate. He is now massively behind us - we have finished and he doesn't have his roof on. He has moved out and seems to be in no hurry to finish. The legal agreement says he has to finish within 3 months of us. I don't know how to go about getting the conditions discharged when we haven't stuck to them. To make things worse, I've just noticed that the skylight we put on the flat roof ( which was a change and not on our original plans, sticks up above the ridge line slightly and is therefore I think in breach of PP. Please please tell me what to do! I'm worried about telling the council anything in case they make us take out the skylight, which would not only ruin the new loft but also probably cost more and we've run out of money!! Aaarggggghg!!!!!
