Decision Maker's Conclusion
- The proposed 125m² unit is more than double the recommended 60m² scale for detached independent living units as defined under Section 2.9.2 of the Development Plan.

- The size and scale of the proposed development would result in the overdevelopment of the site, leading to a depreciation in the value of property and injury to the amenities of the vicinity.
