Knock-Down-Rebuild vs Renovation: Which Makes Sense in Melbourne?

With Melbourne renovation costs rising sharply, more homeowners are discovering that a knock-down-rebuild (KDR) delivers a brand-new home for a similar — or lower — total cost than a major renovation.

When KDR usually wins

Your existing home has structural issues, poor orientation or a layout that can't be fixed without moving walls everywhere. Renovations of this scale routinely exceed $500,000 in Melbourne, at which point a new build often provides better value, energy efficiency and warranty protection.

When renovation wins

Heritage overlays that prevent demolition, strong period character worth preserving, or when only one part of the home needs work. Partial demolition — removing a rear section while keeping the front — is a popular middle path in Melbourne's inner suburbs.

The demolition step

If you land on KDR, demolition typically costs $15,000–$40,000 and takes 1–3 weeks once permits are issued. Comparing multiple demolition quotes early gives you an accurate budget line before signing a build contract.
