Main issues, as the Inspector framed them
- The effect of the proposed dormer window upon the character and appearance of the host building and the surrounding locality, with special attention to The Lake, Bushey Heath Conservation Area
What decided it
The proposed rear dormer window would unacceptably harm the character and appearance of the existing building and conservation area through its disproportionate bulk and dominance of the roof form, and the public benefits did not outweigh this heritage harm.
What the Inspector cited
- Development plan policies
- CS14CS22SADM29SADM30

- Paragraph 205Paragraph 206Paragraph 208
