Main issues, as the Inspector framed them
- the effect of the proposed development on the Castelnau Conservation Area

What decided it
The harmful effect of the proposed vertical slate-clad balustrade on the character and appearance of the Castelnau Conservation Area, combined with unacceptable overlooking impacts on neighbouring properties, outweighed the limited benefit of providing private amenity space.

- Policy LP1Policy LP3Policy LP4Policy LP8
- National Planning Policy Framework
- Paragraph 203Paragraph 205Paragraph 208Paragraph 209Paragraph 135
