Main issues, as the Inspector framed them
- The effect of the development upon the living conditions of the occupiers of 16 & 20 Underne Avenue in terms of daylight, outlook, and privacy
- The effect of the development upon the character and appearance of the area
What decided it
The unacceptable harm to the neighbouring occupiers' outlook and privacy from the raised patio, wall and fencing, together with the harm the fencing caused to the character and appearance of the area, resulted in conflict with the development plan with no material considerations to outweigh it.
the harm to neighbours' living conditions and to the character and appearance of the area from the fencing was found to conflict with the development plan, and there were no material considerations, including the claimed fallback position, sufficient to justify a decision otherwise than in accordance with the plan
