Is it cheaper to renovate or rebuild a house in Melbourne in 2026?

Rebuild wins on cost when the existing home needs more than $400,000 of work, has cracked/heaving slab, non-compliant wiring or asbestos through wet areas. Renovate wins when the existing home is structurally sound, on a heritage overlay (Fitzroy, Carlton, Hawthorn, South Yarra) that blocks demolition, or when you love the shell. For a typical 1970s-90s Melbourne home a full renovation runs $350,000-$650,000; a knockdown-rebuild on the same block runs $520,000-$1,100,000 all-in.

When knockdown-rebuild wins on cost

Rebuild becomes cheaper than renovation when three or more of these apply: cracked or heaving slab, entire re-wire needed, asbestos in wet areas or eaves, non-compliant plumbing throughout, roof structure past its useful life, or a floor plan that requires demolishing more than 40% of internal walls. Once you break past a certain threshold, renovation costs spiral because every trade discovers a new issue behind the old.

When renovation wins - heritage overlays

Roughly 40% of inner and middle-ring Melbourne is under a Heritage Overlay (HO) - Yarra, Melbourne, Stonnington, Boroondara, Bayside, Port Phillip and parts of Moonee Valley. HO lots almost always block full demolition but allow substantial internal renovation. If your home is on an HO, renovation is not a choice - it is the only path. Check via VicPlan (mapshare.vic.gov.au) before you buy.

Melbourne suburbs where each option makes sense

Rebuild is common and cost-effective in outer + middle-ring growth suburbs without heritage restrictions - Templestowe, Bulleen, Vermont, Glen Waverley, Sunbury, Rowville, Berwick. Renovation dominates inner + heritage suburbs - Fitzroy, Carlton, Richmond, South Yarra, Prahran, St Kilda, Hawthorn, Camberwell, Kew, Malvern, Elwood. Bayside (Brighton, Hampton, Sandringham) sits split - each street is different, always check the overlay map.

The middle option - Substantial Renovation

A "substantial renovation" (keeping the existing slab and 1-2 external walls) can dodge parts of the planning-permit hurdle while still delivering 80% of the outcome. Common in Bayside, Stonnington and Boroondara where full rebuild is blocked. Cost is usually mid-way between full reno and full rebuild - around $600,000-$950,000. Requires a builder who is comfortable with heritage integration.

Frequently asked

How much does a knockdown-rebuild cost in Melbourne?

Demolition alone is $18,000-$40,000 depending on size, asbestos content and access. Then rebuild costs $430,000-$1,100,000 turn-key. Add $8,000-$20,000 for temporary accommodation over 14-22 months. Total all-in $500,000-$1,200,000 on a Melbourne metro block.

Can I knock down my heritage-overlay home in Melbourne?

Rarely. Most Heritage Overlays block demolition of the principal facade and any contributory building fabric. Some allow rear demolition if the front facade and character features are retained. Application is via your council planning department, and refusal rates for full HO demolition are 70-90%. Talk to a Melbourne heritage architect before spending on plans.

Is renovating a 1970s Melbourne home worth it?

Depends on the block and heritage status. On a Bayside or Boroondara street where the land value is $1.5M+ and no heritage overlay applies, a $600k renovation on a 1970s home usually delivers a $2.2-2.8M outcome - very profitable. On a Wyndham or Melton block where the land is $350k and rebuilds are cheap, knockdown-rebuild almost always wins.
