Main issues, as the Inspector framed them
- the effect of the proposal on the character and appearance of 21 King Street
- the effect of the proposed development on designated heritage assets with particular regard to the Town Centre Conservation Area and 23-27 King Street, a Grade II Listed Building
- whether the proposed development would provide satisfactory living conditions for the future occupiers with particular regard to noise and odour
- the effect of the proposed development upon the living conditions of neighbouring occupiers at 4 George Street West with particular regard to overlooking
What decided it
The less than substantial harm to the designated heritage assets (Conservation Area and Grade II Listed Building) caused by the incongruous mansard roof and massing, which must be afforded great weight and outweighs the modest public benefits of the development.
