Why it was refused

  1. The proposed extension as shown within plans PP-14703309V1, L(-2)_200.5, L(-4)_200, L(-2)_100 and L(-4)_100 fails to comply with Schedule 2 Part 1 Class A.1(i), A.1(ja) and A.3(a) of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended). This is due to the height of the proposed extension and its distance to the boundary, by reason of its adjoining to an existing extension to the dwellinghouse and the combined development not complying, and by there being no details on materials. Therefore, the proposal fails to accord with the criteria and conditions set out in Schedule 2, Part 1, Class A of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended).
  2. The proposed development as shown within plans PP-14703309V1, L(-2)_200.5, L(- 4)_200, L(-2)_100 and L(-4)_100 shows engineering operations to create new sunken patios, retaining walls and steps. These works go beyond what can be undertaken using permitted development rights and are considered engineering operations. Therefore, the proposal fails to accord with the criteria and conditions set out in Schedule 2, Part 1, Class A of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended).
