Main issues, as the Inspector framed them
- The effect of the proposals, and particularly the side dormers, on the character and appearance of the property and the local area
What decided it
The side dormers would create a bulky, box-like appearance that would be visually intrusive and over-dominant in the street scene, causing harm to the character and appearance of the property and local area that outweighed the personal accommodation benefits.
The personal accommodation benefits to the family did not outweigh the harm to character and appearance of the property and local area
