Main issues, as the Inspector framed them
- Appeal A: the effect of the proposed development on highway safety, with particular regard to parking
- Appeal B: the effect of the proposed development on highway safety, with particular regard to parking; the effect of the proposed development on the significance of a non-designated heritage asset; and the effect of the proposed development on living conditions
What decided it
The under-provision of parking in Appeal A would necessitate additional on-street parking in an area already experiencing significant parking pressures, thereby causing unacceptable harm to highway safety; and in Appeal B, the loss of landscaping to provide the additional parking space would erode the significance of the non-designated heritage asset Nash House.
The adverse impacts of granting planning permission—unacceptable harm to highway safety in Appeal A and harm to a non-designated heritage asset in Appeal B—would significantly and demonstrably outweigh the limited socio-economic benefits of providing one additional flat.
