What To Look For In A Knockdown Rebuild Builder Melbourne

What to Look for in a Knockdown Rebuild Builder in Melbourne

KDR is Melbourne's dominant middle-ring build pathway - Bentleigh, Ashwood, Reservoir, Preston, Coburg, Yarraville. The vetting questions that matter for KDR are different to greenfield. Demolition coordination, service disconnection, heritage clearance and the timeline risk from planning delays.

The vetting checklist that applies to every Melbourne specialist

BuildPilot does not yet match Melbourne builders. Until we do, this is the vetting method we would use ourselves. The first five checks below are specialist-specific; the rest are the core VBA + VMIA + ASIC checks that apply to every domestic builder working in Victoria.

  • Ask if they coordinate demolition in-house or via a licensed demolition contractor - in-house is faster and cheaper on service disconnections
  • Ask their track record on Heritage Overlay refusals and appeals - relevant if your target suburb is Boroondara, Stonnington, Yarra, Port Phillip, Bayside
  • Ask about asbestos removal handling - Class A licensed remover required for friable, Class B for non-friable
  • Ask about interim living arrangements support - most KDR builders have relationships with short-stay providers
  • Verify current VBA registration and category on the public register at vba.vic.gov.au/practitioners/register
  • Verify no active or recent disciplinary decisions on the VBA disciplinary decisions list
  • Confirm Domestic Building Insurance (DBI) will be issued in the builder's name for your contract price under VMIA (all residential work over $16,000)
  • Search the ABN on abr.business.gov.au - name, GST status, date of registration
  • Confirm the entity is not under external administration on the ASIC register

The KDR service disconnection timeline

A Melbourne KDR typically takes 12-18 months total: 4-6 weeks for demolition and service disconnection, 4-8 months for design and Planning Permit (longer if HO), 10-14 months for construction. The service disconnection stage is under-appreciated: connection to water, sewer, gas and power are separate applications with different Victorian utility owners (Yarra Valley Water, City West Water, South East Water, Multinet, AusNet, Powercor, Jemena). Slow disconnection can add 4-6 weeks to the project.

The four red flags that end the conversation

These four signals correlate strongly with builders who have failed or entered administration in Victoria in the last three years. Any of them = walk away.

  • Requested deposit exceeds 10% of contract value (Victorian DBC Act caps deposits at 5%)
  • Vague or evasive answer on DBI eligibility for your specific contract price
  • Refusal to name the Registered Building Surveyor or to let you speak to them independently
  • Aggressive time-limited discount contingent on paying deposit before you have read the contract

Frequently asked

Do I need a Planning Permit to demolish a home in Melbourne?+

Not always for demolition alone if no HO applies. But if the site is in a Heritage Overlay you need a Planning Permit before demolition, and refusal is possible. Check VicPlan before making an offer on any KDR-candidate property.

What is the typical Melbourne KDR total cost?+

$18-35k for demolition + $600-900k for a 200-260m² double-storey rebuild + $8-15k in disconnection and reconnection utility fees + interim rent. Total budget usually $700-950k over the site value.

How long does the interim living stage last?+

Typically 10-14 months from demolition to Occupancy Permit. Some clients rent locally, some stay with family, some sell and re-buy after the build. Cost budget $30-70k for a 12-month rental.

Can I salvage anything from the existing home?+

Yes with builder coordination. Common salvage items: original solid-timber floorboards, cast-iron fireplace surrounds, leadlight, quality bricks for feature walls. Salvage adds 1-2 weeks to demolition but returns ~$5-15k in resale material.

Six questions that save the most money

  1. 1
    Is your VBA registration current, and what class?

    DB-U for unlimited domestic work. Check it on the VBA register and the disciplinary register.

  2. 2
    Show me the Domestic Building Insurance certificate for my job.

    DBI is mandatory before more than a 5% deposit. No certificate, no deposit.

  3. 3
    What soil class is my block and is the slab priced for it?

    Basalt clay in the west is Class H to E. A "standard" site allowance is a variation waiting to happen.

  4. 4
    Is the site-cost allowance fixed or provisional?

    Provisional means you pay the difference. Ask for it fixed after the soil test and survey.

  5. 5
    Is the house all-electric, and what is the induction and heat-pump spec?

    No new gas connections in Victoria since 2024.

  6. 6
    Which benchtop material replaces engineered stone?

    Banned since July 2024. Porcelain, natural stone or laminate.
