Main issues, as the Inspector framed them

The effect of the proposed rear first-floor outrigger extension on the character and appearance of the host property and the surrounding area
The effect of the proposed rear first-floor outrigger extension on the living conditions of the occupiers of No. 57 St. Margarets Grove, with particular regard to outlook

What decided it

The proposal's subordinate design, modest separation distance from the neighbouring boundary, and sloping roof form that mitigates impact on outlook, combined with the condition securing obscure glazing to prevent overlooking, justified allowing the appeal despite departing from SPD guidance.
