Planning permission for semi-detached house on a corner site on Iona Road and Iona Drive in an Architectural Conservation Area. The development consists of the seperation of the property into two attached houses with four and two bedrooms respectively by converting and extending parts of the existing return into a separate attached two bedroom house through the implementation of a party wall. Access to be maintained to 83 Iona Road from Iona Road. The new attached house to be accessed from Iona Drive through an existing gate, subdivision of the back garden and implementation of a boundary fence. The return is to be extended at first floor level with one additional bedroom with a height matching the existing height of the two storey return and at ground floor level with a sunroom/dining room to the front facing Iona Drive. Solar panels to be installed on both houses at roof level of the return facing Iona Drive. On street car parking as per existing to be maintained.
Core Refusal Reason
The proposed development, due to its scale, height, and proximity to the shared boundary, would result in significant overshadowing and an overbearing visual impact on the rear private open space and extension of the neighboring property (No. 85 Iona Road), thereby injuring residential amenities and contravening the Z2 residential conservation zoning objective.
Decision Maker's Conclusion
- The increase in height of the rear return from 4m to 7.5m over a 10m length would cause a significant loss of evening sunlight to the rear garden of No. 85 Iona Road.
- The scale and massing of the first-floor extension along the shared parity wall would result in an unacceptable overbearing impact on the residential amenity of the adjacent dwelling.
- The proposal fails to comply with the design guidance for residential extensions set out in Appendix 17 of the Dublin City Development Plan 2016-2022 regarding the protection of neighboring amenities.
