Officers recommended granting the certificate because the proposal constituted permitted development under Classes B and C, so planning permission was not required.

“The proposed rooflights to the front roof slope constitute an alteration to the roof of a dwellinghouse. They fall to be considered under Class C of the GPDO and need to be judged against criteria C.1 (a) to (e), as well as meet the conditions within paragraph C.2.”
