House Extension Development Permit


JC Engineers was approached to address a refusal notice from Ku-ring-gai Council (NSW) for a proposed house extension. Council refused the application due to the following reasons:

  • Exceed Building Height Restrictions

  • Inadequate Stormwater Planning 

  • Lack of Erosion and Sediment control 

  • Privacy Concerns 

  • Bulk & Aesthetics Issues

  • Lack of adequate Landscaping 

House extension plans
Landscaping plans


Our Planning team reviewed the building plans and identified areas of non-compliance. Recommendations to achieve compliance were provided to the building designer. JCE completed all outstanding specialist documents (i.e. Stormwater Management Plan, Erosion and Sediment Control & Landscape Plans) to be included in the Development Application. 

A Statement of Environmental Effects was prepared to justify the aspects of non compliance within the Development Control Plan. 

Timeframe: Our team completed all relevant works within 3 weeks of engagement. The application was lodged with Ku-ring-gai Council, where our planners managed the application until a decision notice was issued.
