Main issues, as the Inspector framed them

  • the effect of the proposed development on the character and appearance of the area
  • flood risk

What decided it

The proposal fails on two independent grounds: it would harm character and appearance through excessive bulk and boundary siting contrary to design policies, and it fails to demonstrate that flood risk would be adequately managed without reliable evidence of on-site compensatory storage.
