Demolition of existing 2 storey over partial basement house and construction of

Refused

Core Refusal Reason

The proposed demolition of an existing habitable house and its replacement is inconsistent with Policy Objectives CA6 and PHP19, and Section 12.3.9 of the Development Plan, as a strong justification for demolition was not provided and it was not demonstrated that the existing dwelling cannot be retrofitted and reused.

Decision Maker's Conclusion

  • The 2022-2028 County Development Plan establishes a high threshold for the demolition of existing dwellings, prioritizing retrofit and reuse except in cases of proven unhabitability or strong justification.
  • The structural defects and high radon levels identified by the appellant are considered localized maintenance issues or remediable through standard techniques rather than necessitating total demolition.
  • The submitted Sustainability Report and Life Cycle Assessment contained inaccuracies and used an arbitrary 'theoretical extension' for comparison, failing to provide a robust argument for the carbon benefits of a new build over a deep retrofit.
