Main issues, as the Inspector framed them
- The effect of the proposal on the character and appearance of the host property and whether the character or appearance of Rosecroft Gardens Conservation Area would be preserved or enhanced
- Whether the proposal would provide satisfactory standards with regards to fire safety
What decided it
The proposal would cause less than substantial harm to the significance of the conservation area, and the limited public benefits of home improvement do not outweigh the great weight that must be given to the conservation of this designated heritage asset.
The less than substantial harm to the significance of Rosecroft Gardens Conservation Area was weighed against the limited public benefits of home improvement, with the balance tipping decisively against the proposal because no public benefits could outweigh the great weight attached to heritage harm.
