Main issues, as the Inspector framed them

  • The effect of the proposed dormer extension on the character and appearance of the host dwelling, the terrace of which it forms part and its surroundings

What decided it

The proposed dormer extension would undermine the design integrity and symmetry of the terrace, which was fundamental to the original design, and would be perceived negatively from the approach road and green space.

Framework references: 12
