Main issues, as the Inspector framed them
- the effect of the proposed development on the character and appearance of the host property and the area
- the living conditions of the occupiers of the neighbouring property at No. 240 Cannon Lane with particular regard to overshadowing and outlook
What decided it
The proposed extension would result in unacceptable harm to the character and appearance of the host property and the area by virtue of its scale, siting and design, which would fail to achieve appropriate subordination and would create an incongruous addition.
The benefits of providing additional accommodation and high quality design were outweighed by the substantial harm to the character and appearance of the host property and the area.
