Hi I've just done a small loft conversion with a dormer which I was advised I could do under permitted development , I instructed independent inspector s and was told I could start 5 days after they submitted the application. I was also advised to get a certificate of lawfulness but was told all would be OK to start I waited 2 weeks before I started then started , I've now been refused the certificate of lawfulness because the permitted development has been removed in the area . I now have to submit a full planning application, how likely am I to get the permission now that the conversation is almost complete . Is there any advice on anything I can say to help my application. It's not in a conservation area
