Main issues, as the Inspector framed them
- the effect of the appeal extensions on the character and appearance on the terrace, streetscene and surrounding area
- the effect of the raised patio on the living conditions of the neighbouring occupiers at 6 Dawlish Drive and 10 Dawlish Drive, particularly as regards overlooking
- the effect of the rear extension on the living conditions of the neighbouring occupier at No 10 particularly as regards outlook, overshadowing and loss of light
What decided it
The unauthorised extensions caused significant harm to character and appearance and the living conditions of neighbouring occupiers through overlooking and loss of outlook, contrary to the development plan with no material considerations to outweigh this.
