Core Reason for the Refused Part
The proposed granny flat extension constitutes overdevelopment of a limited site, would be seriously injurious to the visual and residential amenities of the area, and fails to meet Development Plan criteria requiring such units to be subsidiary and capable of being readily subsumed back into the primary dwelling.
Decision Maker's Conclusion
- The proposed high-level ground floor gable window is acceptable as it provides light without giving rise to overlooking of the side passage.
- The granny flat extension represents overdevelopment of the site, causing significant visual impact and resulting in private open space that lacks adequate privacy due to overlooking.
- The design and layout of the extension do not allow it to be easily integrated back into the main house, directly contravening the requirements of Section 12.3.7.3 of the Dun Laoghaire-Rathdown County Development Plan 2022-2028.
