Refused

Core Refusal Reason

The proposed development constitutes over-development of a restricted site, providing substandard residential accommodation for the existing dwelling and creating a significant traffic hazard through the intensification of an inadequate vehicular access.

Decision Maker's Conclusion

  • The subdivision would result in the original house (No. 13) falling significantly below minimum standards for gross floor area, internal storage, and bedroom sizes, thereby reducing its residential amenity.
  • The intensification of the existing access point on a site with restricted frontage and insufficient turning area would create a traffic hazard for both motorists and pedestrians.
  • While the principle of infill development is supported under the 'RES' zoning, the current proposal fails to integrate satisfactorily and does not justify the provision of substandard accommodation.
