Main issues, as the Inspector framed them

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

What decided it

The proposed roof form, despite the raised ridgeline and rear gable, would respond sensitively to the character of the area by retaining a hipped form consistent with the predominant architectural style of Brockley Avenue and remaining proportionate to the resulting building.
