Main issues, as the Inspector framed them

The effect of the proposed wraparound extension on the character and appearance of the host dwelling and surrounding area

What decided it

The scale, height and bulk of the wraparound extension would visually dominate the host dwelling and seriously harm its character and appearance, contrary to development plan policy and supplementary planning guidance.

Plan policies cited: Policy D3 of the London Plan (2021), Policy QD9 of the Lewisham Local Plan (adopted 2025)
