The planning dept use high definition aerial photos to check building matters here mate, and they can measure the size of your shed/garage etc in great detail. You get taken to court, have to remove the offending structure if you dont have the correct permission, and a £2000 fine. Not good.
14 week wait from sending the plans in, to getting a reply. Absolutely farkin ridiculous. Almost there now, base dug out, planning permission almost sorted, ready to build a Batcave. Pics posted of the build once it gets underway.
