Main issues, as the Inspector framed them

the effect of the proposed development on the character and appearance of the host property, the pair of semi-detached properties, and the immediate area, with particular regard to its scale and design
the living conditions of neighbouring occupiers at no.21, with particular regard to outlook and daylight
