Main issues, as the Inspector framed them

  • The effect of the proposed development on the character and appearance of the host building and its surroundings
  • The effect of the proposed development on the residential amenities of neighbours (whether unacceptable harm would be caused by overbearing appearance or overshadowing)

What decided it

The proposed extension would create an unacceptably long, high boundary wall that would intrude on the outlook of the neighbouring property and cause unacceptable overbearing harm, outweighing any benefits of the development.
