Often yes, particularly for rear or second-storey additions. However, this depends on:

  • The scope of works
  • Structural changes
  • Bathroom/kitchen relocations
  • Safety considerations

We discuss staging options to minimise disruption wherever possible.

Build time depends on scale and complexity:

  • Small additions: 8–12 weeks
  • Medium extensions: 3–5 months
  • Large or second-storey additions: 5–8 months

Weather, material availability and approval timelines can affect schedules.

Yes. We carefully design extensions to blend seamlessly with your existing home, including:

  • Roof pitch and materials
  • Brick or cladding profiles
  • Ceiling heights
  • Internal finishes

Our goal is for the new addition to feel like it has always been part of your home.

In most cases, yes. Home extensions and additions generally require planning and building approval under South Australia’s Planning & Design Code.

Approval requirements depend on factors such as:

  • The size and height of the extension
  • Boundary setbacks
  • Site coverage
  • Heritage or character overlays
  • Bushfire or flood-prone zones

We manage the entire approval process on your behalf, including documentation, lodgement and coordination with relevant authorities.

Approval timeframes vary depending on the complexity of the project and whether planning consent is required.

Typical timeframes:

  • Simple, compliant developments: 2–6 weeks
  • More complex or performance-assessed projects: 4–12+ weeks

We provide realistic timeframes during your consultation so you know what to expect.
