Why it was refused

  1. The proposed development would fail to satisfy the criteria set out in Paragraph A.1(f)(i), A.1(i), and A.2(a) for the permitted development Schedule 2, Part 1, Class A of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended) because; the proposed rear extension would extend beyond the rear wall of the original dwelling house by more than 3 metres, the enlarged part of the dwellinghouse would be within 2 metres of the boundary of the curtilage of the dwellinghouse, but the height of the eaves of the enlarged part would exceed 3 metres, and the proposed extension would be clad in render.

From the council's decision notice.
