Main issues, as the Inspector framed them

  • the effect of the proposed development on the character and appearance of the host property and the wider area
  • the living conditions of the occupants of No.9 Joiners Lane, with particular regard to outlook and dominance
  • protected species

What decided it

The combination of significant harm to character and appearance through excessive bulk and massing, adverse effects on neighbouring living conditions through visual dominance, and unresolved uncertainty regarding protected species due to missing survey information meant the proposal conflicted with the development plan with no material considerations of sufficient magnitude to outweigh this harm.
