Kellett Design Group has a lot of experience with unauthorized structures. This knowledge allows outlining the most cost-effective procedure to get the project approved with local councils. Types of structures to get approved: 

  • Retaining walls
  • Carports
  • Garages
  • Boundary walls
  • Alfrescos
  • Additions to dwellings


You can get your unauthorized structure/addition approved with the following procedures:

  • Create architectural drawings of the project – normally, this requires a detailed site measure up.
  • Carry out a structural inspection & provide structural certification for building approval.
  • Carry out a site inspection for building compliance with NCC and issue a BA18 document – Certificate Building Compliance

All of the above packaged up and submitted to the council will grant you prompt approval.
