Main issues, as the Inspector framed them
- The effect of the proposal on the character and appearance of the Barnsbury Conservation Area
What decided it
The limited public visibility of the mansard extension from the main public views, combined with the existing presence of other roof extensions in the terrace and the already limited architectural unity at roof level, meant the proposal would not detract from the appearance of the terrace or the heritage significance of the Conservation Area.
