Core Planning Reasoning
The Inspector recommended granting permission subject to a significant amendment requiring the two-storey side extension to be set back to align with the front elevation of the adjacent property (No. 45), ensuring the development does not seriously injure the visual or residential amenities of the area.
Decision Maker's Conclusion
- The principle of the proposed residential extension is acceptable under the 'Objective A' zoning of the Dún Laoghaire-Rathdown County Development Plan 2022-2028.
- The proposed side extension, as originally designed, would have an unacceptable overbearing impact and would be visually domineering relative to the neighboring property at No. 45 due to its height and forward projection.
- A condition requiring a setback of the side extension to align with the neighboring building line effectively mitigates the negative impacts on residential amenity and streetscape character.
