Core Refusal Reason
While the Planning Authority initially refused the application due to the dormer's excessive size and lack of setback, the Inspector recommended a grant of retention permission on appeal, concluding that proposed modifications to set the structure back from the boundary and reinstate eaves would mitigate visual dominance and ensure substantial compliance with the Dublin City Development Plan.
Decision Maker's Conclusion
- The proposed modifications submitted during the appeal, including a 500mm setback from the east edge and the reinstatement of eaves, sufficiently reduce the visual scale and dominance of the dormer extension.
- The attic level windows do not result in a significant increase in overlooking compared to existing terrace configurations, and the extension's location to the north of the dwelling prevents significant overshadowing impacts.
- The removal of the chimney stack has no significant impact on the streetscape, and the modified development is consistent with the proper planning and sustainable development of the area.
