Why it was refused
- The proposed construction of an additional storey would fail to comply Class AA.2. (2) (c) and AA.2. (3) (a) of Part 1, Schedule 2 of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended), as no application for prior approval has been sought and no prior approval given and the roof pitch the of the dwellinghouse following the development would not be the same as the roof pitch of the existing dwellinghouse. Furthermore, the proposal would fail to comply with the provisions of Class A and Class B of the General Permitted Development Order. Formal planning permission would therefore be required.
