Decision Maker's Conclusion
- The applicant failed to provide written evidence or a Section 5 Declaration confirming that the existing use of the main dwelling as a care facility is exempted development under Class 14(f) of the Planning & Development Regulations.
- The proposed drainage strategy was deemed deficient as it lacked site-specific soil permeability tests and detailed soakaway designs required to demonstrate compliance with SuDS principles and BRE Digest 365.
- Insufficient technical evidence was submitted to confirm that the existing on-site wastewater treatment system has the necessary hydraulic and organic capacity to accommodate the additional loading from the proposed unit in accordance with EPA standards.
