Main issues, as the Inspector framed them

  • the effect of the proposed development on the character and appearance of the area, including the Kingston Hill/Coombe Hill Strategic Area of Special Character (SASC)
  • the living conditions of the occupiers of Nos 11 and 13 Coombe Ridings, with particular regard to privacy and noise

What decided it

The harmful effect on the character and appearance of the area caused by the cumulative impact of the extensions, unconventional roof form, and overall composition of the remodelled dwelling outweighed any other considerations.
