Permission for modifications and extension to the existing dwelling house, including: (A) Alterations to the existing internal layout, (B) Alterations to existing dwelling elevations including external finishes, alterations to openings and first-floor windows, (C) Demolition of single-storey section, (D) Construction of a two-storey extension with single storey link to the side of the existing dwelling, (E) Installation of a new septic tank, and proposed soakaways for surface water and all ancillary works
Core Refusal Reason
The proposal was refused due to its excessive scale and inappropriate design on a designated scenic route, failure to demonstrate adequate visibility sightlines, insufficient wastewater treatment capacity, and lack of information to rule out adverse impacts on European protected sites.
Decision Maker's Conclusion
- The proposed extension is excessive in scale, bulk, and design, appearing as a separate dwelling that would be obtrusive on a designated scenic route (SR 14) and out of character with the rural landscape.
- The applicant failed to demonstrate that necessary visibility sightlines at the entrance can be achieved or maintained, posing a potential traffic hazard to public safety.
- Technical deficiencies regarding the capacity of the wastewater treatment system and the absence of an Appropriate Assessment screening report prevent the Planning Authority from ensuring public health and environmental protection for nearby European sites.
