Main issues, as the Inspector framed them
- The effect of the proposed single storey rear extension on the living conditions of the residents of 22 Teddington Park with reference to sunlight, daylight and visual impact
What decided it
The visual intrusiveness and overbearing appearance of the proposed single storey extension when viewed from the neighbouring property's garden and patio, combined with the fallback position of the Certificate of Lawfulness for the dormer, led to a split decision allowing the dormer but dismissing the extension.
What the Inspector cited
- Development plan policies
- Policy 46 of the Richmond upon Thames Local Plan
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.
