We are in the middle of trying to sell our house, and the survey has come back with a question about planning and building control for the conservatory. Our builder advised us that we didn't need it, but the planning office have said that if it is more than 3m square, we needed it. Ours is 3.048m by 2.74m. The planning office have said, 'I wouldn't worry about it,'
but I have no idea whether or not we need to apply for retrospective planning permission.
I need some advice from people who have perhaps been in the same boat.
