Main issues, as the Inspector framed them

The effect of the proposed development on the character and appearance of the host dwelling which the Authority recognise as an undesignated heritage asset, and on the Harpenden Conservation Area

What decided it

The proposed dormer would appear overly dominant and incongruous with the original scale, character and appearance of the host dwelling and the Harpenden Conservation Area, causing less than substantial harm with no public benefits to outweigh it.

Framework references: 215, 216

Plan policies cited: Policy 69, Policy 72, Policy 85, Policy 87, Policy ESD1, Policy ESD2
