Main issues, as the Inspector framed them
- The effect of the proposed development on the character and appearance of the area
What decided it
The substantial size and mansard-style form of the proposed extension would appear as a discordant and incongruous feature that would disrupt the unbroken butterfly roof pattern and uniformity characterising the terrace, thereby causing harm to the character and appearance of the area contrary to the development plan.
The appellant's reliance on housing optimisation policies in the London Plan 2021 did not outweigh the harm that would arise to the character and appearance of the area.
What the Inspector cited
- Development plan policies
- Policy LP1 of Hackney Local Plan 2033Policies D5, D6, D8, H2 and H10 of The London Plan (2021)Residential Extensions and Alterations Supplementary Planning Document
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.
