Main issues, as the Inspector framed them
- the effect of the proposed development on the architectural integrity of the host property, the terrace of which it is part and thereby the street scene
- the effect of the proposed development on the living conditions of the occupiers of number 303 in terms of the proposals potential to appear overbearing and create an increased sense of enclosure
What decided it
The proposed hip to gable alteration and the overall bulk of the extensions would result in unacceptable harm to the architectural integrity of the host property and the terrace, contrary to local plan and SPG policies on character and appearance.
The benefits of improved housing accommodation and quality of life for the appellant's family were outweighed by the unacceptable harm to the architectural integrity of the host property and the street scene.
