Core Planning Reasoning
The proposed development is consistent with the 'A' residential zoning objective and the policy framework of the Dun Laoghaire-Rathdown Development Plan 2022-2028, as it provides for appropriate domestic extensions that do not significantly impact the residential or visual amenities of adjoining properties.
Decision Maker's Conclusion

- To protect the privacy of adjoining properties at 4 Trimleston Road and 59 Trimlestown Gardens, the proposed first-floor window in the north elevation must be omitted and replaced with a render finish.
