Main issues, as the Inspector framed them

  • Whether the proposed development would serve to preserve or enhance the character or appearance of the Conservation Area

What decided it

The incongruous design of the proposed mansard roof, which would be clearly visible from Bridge Road and would contrast sharply with the unified design of existing mansards, causing visual harm to the Conservation Area with no identified public benefits to justify the harm.

Plan policies cited: LP policy 29
