Core Reason for the Refused Part
The proposed front dormer is visually incongruous as it protrudes above the existing ridge line, failing to comply with specific roof alteration standards in the County Development Plan.
Decision Maker's Conclusion
- The proposed dormer on the front elevation protrudes above the existing ridge, resulting in a visually incongruous design that detracts from the area's character.
- The development fails to meet the requirements of Section 12.3.7.1 (iv) of the Dún Laoghaire-Rathdown County Development Plan 2022-2028 concerning attic and roof alterations.
- Granting permission would establish an undesirable precedent for similar developments and would be contrary to proper planning and sustainable development.
