Hi
Total newbie here, but confused by permitted development rules.
House is detached with garage at the rear (blue on image) at the boundary. We are looking to do a single storey rear extension 6m back for the full length of the house. Trying to find out if we do it for the full width of the house including the garage (orange on image). Can’t seem to find anything on if it can be done behind an adjoining garage without planning permission.
would be great full for any advice on this
many thanks
