Faster turnarounds for Class 1a/ Class 10 projects

We're hearing from many clients about the advantages of homeowners arranging an early site survey. This saves time and provides required detail, from the beginning stages of residential, landscaping and pool projects in Brisbane and surrounding regions.

Information from site surveys can help

- create a detailed site plan

- determine if any siting variations (relaxations)/ Build over Asset (BOA) facilitation may be required

To get started with the Building Approvals (BA) process and associated council facilitation, professionally drawn plans should show

- location of existing structures and main infrastructure

- elevation / heights

- details of fences/ boundaries on site

- accurate dimensions of all outbuildings / sheds, including site coverage and distances to outermost projection (OMP)

- details of the natural Ground Levels (and reduced levels/ RLs) a well as the materials proposed.

Case Study: combined heights for fences/ retaining walls, triggering siting variations (relaxations)


For a retaining wall, approval is required

- where the wall exceeds 1m total height

- building work is within 1.5m of a structure

- if the footing for the retaining wall will impose a surcharge loading to any nearby infrastructure/footings.
