Main issues, as the Inspector framed them

  • the effect of the proposal on the character and appearance of the area, including heritage assets
  • biodiversity
  • the Borough's housing stock

What decided it

The less than substantial but considerable harm to the conservation area, combined with biodiversity harm and loss of housing units, outweighed the modest public benefits and engaged the presumption against development in paragraph 11d)ii of the Framework.

The harm to the conservation area, biodiversity and housing stock outweighed the benefits of affordable housing contribution, bringing a vacant property into use, and modest economic and sustainability benefits
