Main issues, as the Inspector framed them

  • The effect of the development on the character and appearance of the host dwelling and surrounding area, including on the Spring Grove Conservation Area

What decided it

The canopy's excessive depth of projection beyond the original dwelling walls, combined with its height and poor design integration, causes less than substantial harm to the character and appearance of the conservation area with no public benefits to justify this harm.
