I believe if its attached to the house its classified as an extension even though clearly for "normal people" its no such thing
You may want to check with the same planning officer if it was a similar structure but not connected to the house and that it complied with the limits to height etc it would be ok, if not could be explain specifically why not.
Then assuming he says yes if its not connected then its not an extension and needs to comply with outbuilding rules as opposed to extension rules, then move it 5mm away from the house. Reinforce the corners a little, add a couple of extra down pieces at the back (where it would have connected to the house), add a few extra securing bolts and you should be fine.
This is useful as is the link to the defra site that is supposed to list all the designations, zoom in to your area, click the respective options on the left side.
