Core Refusal Reason
While the Planning Authority refused permission due to potential visual overbearing and overshadowing of No. 8 Mount Auburn, the Inspector recommended a grant of permission, concluding that significant ground level differences and technical shadow analysis demonstrate no undue impact on residential amenity.
Decision Maker's Conclusion
- The proposed development is acceptable in principle as it is located in an area zoned to protect and improve residential amenity.
- The significant difference in ground levels between the subject site and neighboring properties (specifically No. 8 Mount Auburn being significantly higher) effectively mitigates any potential overbearing impact or loss of light.
- The proposal complies with the standards for first-floor extensions set out in the County Development Plan and will not negatively impact the visual amenity or property values of the area.
