Main issues, as the Inspector framed them

  • The effect of the proposal on the character and appearance of the host property, the terrace, and the area, including whether it would preserve or enhance the character or appearance of the Graham Road and Mapledene Conservation Area

What decided it

The mansard roof extension, being set back behind the front parapet with a shallow pitched roof slope and low-profile conservation-type roof lights, would not break the important parapet line of the terrace and would be largely concealed in streetscene views, thereby preserving the character and appearance of the conservation area.
