Main issues, as the Inspector framed them

What decided it
The substantial bulk, depth and incongruous design of the proposed rear extension would unacceptably harm the character and appearance of the host dwelling and surrounding area, and would unacceptably reduce daylight and harm the outlook of the neighbouring occupier at No 16.
