Why it was refused

  1. The proposal fails to comply with the limitations of Class A of Part 1, Schedule 2 of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended). As per the submitted plans, the enlarged part of the dwellinghouse would extend beyond the side elevations of the existing rear extension, and would have a width that exceeds half the width of the original dwellinghouse, contrary to the limitation set out in paragraph A.1(j)(iii). As such planning permission is therefore required.

From the council's decision notice.
