SD21B/0210
Extension and refurbishment of existing two storey three bedroom semi-detached dwelling of 103sq.m consisting of: new reconfigured vehicular entrance with electric gate and additional permeable paving with new single storey ground floor front; side and rear extension of 44sq.m with lean-to pitched roof and roof lights; detached single storey home office of 11.5sq.m with new rear garden side access from Liffey Crescent with landscaping to remaining 25sq.m garden area; new internal stairs to converted attic store of 24sq.m with dormer window to gable roof and associated site works.
Core Refusal Reason
The proposal constitutes overdevelopment of a restricted site and poses significant risks to public water and drainage infrastructure due to inadequate setbacks from existing mains.
Decision Maker's Conclusion
- The proposed development is located too close to a 300mm public surface water sewer and a 100mm public watermain, failing to meet minimum setback requirements and risking structural damage and restricted maintenance access.
- The scale of the extension combined with a proposed home office results in overdevelopment of the 0.0240-hectare site, leaving insufficient private amenity space for a three-bedroom dwelling.
- The development would set an undesirable precedent for similar works that are harmful to residential amenities and contrary to the proper planning and sustainable development of the area.
