Main issues, as the Inspector framed them
- The effect of the proposed development on the character and appearance of the host building and on the surroundings of the High Street and the Monken Hadley Conservation Area
What decided it
The side dormer extension would be substantially larger and more prominent than comparable permitted dormers on the adjacent property, would fail to preserve the character and appearance of the Conservation Area, and would not be outweighed by any public benefits, whereas the rear extensions would be acceptable in design terms.
