A knockdown rebuild is often the most practical way to get a new custom home on an established block without the uncertainties of renovating an ageing structure. But the process involves more considerations than simply demolishing and starting again.
Do You Need a Planning Permit to Demolish?
In many cases, demolition of a house in Victoria does not require a planning permit. However, demolition may trigger a planning permit if the property is within a Heritage Overlay or Neighbourhood Character Overlay.
Building Permit for Demolition and Rebuild
Demolition work requires a building permit from a registered building surveyor. The demolition contractor must also comply with WorkSafe Victoria requirements regarding asbestos and site safety.
Design Opportunities and Cost Comparison
Unlike a renovation, a knockdown rebuild allows complete design freedom.
- Full design freedom — no existing structure constraints
- Optimised solar orientation from scratch
- Achieves current NCC 7-star energy standard
- Typically more cost-effective than major renovation
