Main issues, as the Inspector framed them

  • The effect of the development on the significance of the Cornwall Conservation Area

What decided it

The mansard roof extension fundamentally alters the traditional form of concealed roof slopes characteristic of the conservation area and fails to preserve the characteristic roof form, unacceptably harming the significance of the conservation area with insufficient public benefits to justify the less than substantial harm.
