Core Planning Reasoning
The proposed development was refused on the basis of Appropriate Assessment; specifically, that it cannot be excluded, based on the available information and the absence of a Natura Impact Statement, that the project would not have a significant effect on the Horn Head and Rinclevan SAC and the Horn Head to Fanad Head SPA, particularly concerning wastewater capacity and surface water discharge pathways.
Decision Maker's Conclusion
- The physical extensions and design modifications are consistent with the character of the existing permitted dwelling and would not result in a material negative impact on the residential amenities of third parties.
- The existing site entrance is considered safe in its current configuration, and the omission of previous planning conditions relating to road widening and material removal is acceptable in principle.
- Refusal is ultimately necessitated by the Habitats Directive, as the increase in bedroom count likely exceeds the installed wastewater treatment capacity, and the lack of clarity regarding drainage pathways to protected Natura 2000 sites precludes a finding of no significant effect.
