Why it was refused

  1. The proposed development, by reason of the cumulative size, scale and relationship of the proposed side extension and the existing garage building, would fail to comply with the limitations set out under Schedule 2, Part 1, Class A, paragraph A.1(j) of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended). In particular, the development cumulatively would exceed 4 metres in height, contrary to paragraph A.1(j)(i), and would result in a structure which, when taken together with the existing garage, would have a width greater than half the width of the original dwellinghouse, contrary to paragraph A.1(j)(iii). As such, the proposed development would not constitute permitted development within the meaning of Schedule 2, Part 1, Class A of the Order and would require planning permission. See the attached Appeal Notes for details of appealing this decision.

From the council's decision notice.
