Core Planning Reasoning
The proposed extension is considered subordinate in scale and design, consistent with the Objective A zoning of the area, and will not negatively impact the visual or residential amenities of the vicinity through overshadowing, overlooking, or overbearing effects.
Decision Maker's Conclusion
- The extension is subordinate in design and scale to the existing end-of-terrace dwelling and will not be visually obtrusive within the streetscape.
- The proposal will not result in significant overshadowing or loss of privacy for neighboring properties due to the modest ridge height, separation distances provided by a pedestrian passageway, and the use of high-level windows on the side elevation.
- The development complies with the Dun Laoghaire Rathdown County Development Plan 2022-2028 policies regarding residential extensions and the protection of existing amenities.
