Main issues, as the Inspector framed them
- the effect of the proposed development upon the character and appearance of the house and surrounding area and upon the living conditions of occupiers of 16 Harcourt Road, with particular regard to light and outlook
- whether the proposed development would lead to an increased risk of flooding
What decided it
The proposal conflicts with design and flood risk policies: the side extension would harm character and appearance through loss of symmetry and an overly elongated roof form, and the development fails to demonstrate acceptable flood risk through proper assessment and surface water management.
