Main issues, as the Inspector framed them
- The effect of the proposed extensions at No. 80 on the appearance of the existing house and its immediate surroundings
What decided it
The proposed extension to the rear dormer would create an unfortunately vertical-faced second storey that would become more dominant and overbearing, causing significant harm to the appearance of the host dwelling and failing to comply with local design guidance requiring a positive contribution to the street scene and character of the area.
What the Inspector cited
- Development plan policies
- Policy EN1Supplementary Planning Document for the Design of Residential Extensions and New Residential Development (April 2011)
How the Inspector dealt with each one is set out in the app, in order: the development plan, national policy, housing land supply, other considerations and the planning balance, beside the letter.
