Main issues, as the Inspector framed them

the effect of the proposed development on the character and appearance of the host property and surrounding area

What decided it

The scale, depth, and detailing of the proposed development would result in an overly dominant and visually intrusive addition that fails to respect the character and appearance of the host dwelling and the wider area.

Plan policies cited: Policy 28 of the Richmond upon Thames Local Plan (2025)
