Main issues, as the Inspector framed them

  • The effect of the proposed development upon the character and appearance of the host dwelling and the surrounding area

What decided it

The proposal would substantially infill one of the corresponding first-floor recesses that are important to the articulation and balanced composition of the semi-detached pair, creating unacceptable asymmetry if implemented independently without certainty of matching development at the adjoining property.
