Core Refusal Reason
The proposed development is considered to be of an excessive scale, height, and internal configuration that exceeds the requirements for 'modest' ancillary accommodation, effectively creating a detached independent dwelling unit that contravenes Section 12.3.7.4 of the County Development Plan.
Decision Maker's Conclusion
- The structure's floor area (c. 67sqm for the extension) and full suite of residential facilities (kitchen, living area, ensuite bedroom) make it capable of independent living, which directly conflicts with the definition of a modest ancillary habitable room.

- The proposal fails to protect the residential amenity of the existing and adjoining dwellings and is contrary to the overarching 'Objective A' zoning and specific development management standards of the Dún Laoghaire-Rathdown County Development Plan 2022-2028.
