Main issues, as the Inspector framed them
- The effect of the proposed development on the architectural integrity of the host property, the terrace of which it is part and thereby the street scene
What decided it
The proposed extension would appear as a bland, dominant and incongruous addition harmful to the architectural integrity of the host property and the wider street scene due to its overall width and proposed relationship with the street.
The benefits of providing larger family accommodation and improving the existing housing stock, together with the absence of third-party objections, did not outweigh the harm to character and appearance of the host property and street scene.
What the Inspector cited
- Development plan policies
- Policy CC1Policy CC2Policy SC7
