Core Refusal Reason
The proposal failed to justify the need for an independent living unit, exceeded floor area guidelines for such units, and lacked sufficient technical details regarding wastewater and surface water management.
Decision Maker's Conclusion
- The applicant failed to demonstrate a genuine need for the independent living unit, which at 91sqm significantly exceeds the 50sqm guideline and constitutes an unauthorized self-contained dwelling rather than ancillary accommodation.
- The presence of unauthorized structures on the site, specifically a metal shed and greenhouse, precludes the Planning Authority from granting permission for the development in this instance.
- Insufficient information was provided to confirm that the existing wastewater treatment system and surface water disposal arrangements are capable of handling the additional load, posing a potential risk to public health and the environment.
