Main issues, as the Inspector framed them
- The effect of the development on the character and appearance of the area, including the Barn Hill Conservation Area
- Whether the development provides adequate living conditions for existing and future occupants, with regard to internal floor space and private amenity space
- The effect of the development on highway safety, with regard to parking
- The effect of the development on the living conditions of neighbouring residents, with regard to noise and disturbance
What decided it
The development significantly harms the character and appearance of the Barn Hill Conservation Area and fails to provide adequate internal floor space for living conditions, which together outweigh any neutral effects on highway safety and neighbouring amenity.
The neutral effects on highway safety and neighbouring living conditions do not outweigh the significant harm to the character and appearance of the conservation area and the inadequate living conditions for future occupants.
