Core Refusal Reason
The proposed roof alterations, specifically the rear dormer and 0.5-metre ridge height increase, are considered excessive in scale and massing, resulting in a visually incongruous impact on the streetscape.
Decision Maker's Conclusion
- The scale, bulk, and massing of the rear dormer and the 0.5-metre increase in ridge height are deemed excessive and visually incongruous within the existing roofscape.
- The development would result in a significant negative visual impact on the character of the streetscape and fails to comply with specific standards for roof alterations in the County Development Plan.
- Granting permission would set an undesirable precedent for similar developments in the area, contrary to the proper planning and sustainable development of the locality.
