You’ve lived in your Melbourne suburb for years, the kids walk to school, you know every neighbour by name, and the local café makes your coffee exactly right. But your house? The layout doesn’t work, the heating bills are astronomical, and you’re tired of patching up problems that never really get fixed.
A knock-down rebuild lets you stay exactly where you are while creating a brand-new house that fits your life. This guide walks you through the complete knock down rebuild process, providing honest timelines, current costs, and practical insights from helping Melbourne families navigate this journey.
Disclaimer: This provides general information about knock-down rebuild. Costs, timelines, and requirements vary based on your property and council area. Always consult qualified building professionals and your local council for advice specific to your situation.
Is Knock Down Rebuild Right for You?
When It Makes Sense
A knock-down rebuild works best when renovation costs approach new build costs. If your builder quotes $300,000 to renovate a house with structural issues or asbestos, you’re better off starting fresh.
This approach works brilliantly when you love your location but hate your house. Maybe you’re in a great school zone, close to family, or you’ve built a community you don’t want to leave. The knock down rebuild process lets you keep all of that while getting modern energy efficiency, better use of space, and a home that actually works for how you live.
When to Consider Alternatives
Heritage-listed homes face serious restrictions. Check the Victorian Heritage Database to see if your property has heritage protection. Some Melbourne councils, particularly Boroondara and Stonnington, protect character homes.
Blocks under 300 square meters often face design challenges due to setback requirements under ResCode. Budget matters too—Melbourne knock-down rebuilds typically cost $510,000-$1,024,000 total.
The 10-Step Knock Down Rebuild Process
Step 1: Initial Feasibility and Council Research
Greater Melbourne has 31 different councils, each with different planning rules. Check your property’s zoning on your council’s planning maps. General Residential Zone is common in middle suburbs, while Neighborhood Residential Zone appears in inner areas with stricter controls.
Look for overlays—extra rules on top of zoning. Heritage Overlay might prevent demolition. Vegetation Protection Overlay means you can’t remove certain trees without permission. Bushfire Management Overlays add fire-resistant requirements. The Victoria Planning Provisions explain each zone type.
Typical costs: $0-$500 for council searches through LANDATA.
Step 2: Engage a Builder
Talk to builders registered with the Victorian Building Authority who specialize in knock-down rebuilds. Interview at least three. Ask how many KDR projects they’ve completed in Melbourne recently, what’s included in their fixed-price contract, and who manages council approvals.
A good home builder assesses your block in person before quoting—looking at access for trucks, soil issues, service connections, and how slope affects costs.
Typical costs: Free initial consultations.
Step 3: Design Your New Home
Work with a designer to develop floor plans that suit your family and comply with council requirements. Melbourne inner suburbs often have narrow blocks requiring smart design to maximize light.
Your design must meet ResCode requirements for private open space (usually 25% of your block), setbacks, wall heights, and neighbor overshadowing. Get these wrong and the council rejects your application.
Think five to ten years ahead. Do you need a home office? Will aging parents move in? Plan for proper storage—often overlooked in Melbourne homes.
Consider EV charging infrastructure, solar panel rough-in, and insulation beyond minimum standards.
Typical costs: $5,000-$25,000+, depending on custom vs standard designs.
Step 4: Obtain Planning Permit
Under the Planning and Environment Act, councils have 60 statutory days to decide on applications, but they often request additional information, extending timelines.
Your application includes site plans, elevation drawings, floor plans, shadow diagrams, waste management plan, landscape plan, and planning report.
Some applications require neighbor notification. If neighbors object, you might modify your design or attend a council meeting. Serious disputes can go to VCAT, adding months.
Boroondara and Stonnington councils have stricter controls and longer processing times. Casey and Cardinia typically process faster.
Typical costs: $1,500-$3,000 for application fees and consultant costs. Timeline: Realistically, 3-4 months, including document preparation.
Step 5: Secure Finance and Budget
Construction loans release funds in stages as construction progresses—called progress payments. Map out your complete budget, including often-forgotten costs.
Melbourne Knock Down Rebuild Budget (September 2025)
| Item | Cost Range |
|---|---|
| Demolition (including asbestos) | $15,000 – $35,000 |
| New build (3-4 bed) | $400,000 – $800,000 |
| Permits & approvals | $10,000 – $20,000 |
| Professional fees | $15,000 – $40,000 |
| Temporary accommodation (12-18 months) | $24,000 – $36,000 |
| Storage & connection fees | $5,000 – $12,000 |
| Landscaping | $15,000 – $50,000 |
| Contingency (10-15%) | $46,000 – $93,000 |
| TOTAL | $510,000 – $1,024,000 |
Costs vary based on home size (typically $2,000-$3,000/sqm), finishes, site complexity, and location. These figures represent typical projects—obtain detailed quotes for your specific situation.
Hidden costs: moving twice, council contributions, driveway crossover reconstruction, and new fencing.
Typical costs: $500-$1,500 loan establishment fees.
Step 6: Obtain Building Permit
Building permit confirms your design meets the National Construction Code for structural safety, fire safety, and energy efficiency.
Engage a private building surveyor registered with the VBA. They review construction drawings, structural engineering certification, energy efficiency reports (6-star minimum under NatHERS), soil tests, and hydraulic drawings.
The surveyor conducts mandatory inspections during construction to confirm that your builder follows approved plans.
Typical costs: $2,000-$5,000 for surveyor fees and reports.
Step 7: Arrange Temporary Accommodation
You need somewhere to live for 12-18 months—demolition takes weeks, construction takes 8-14 months, and you can’t move in without an occupancy permit.
Melbourne’s rental market can be tight. Start looking early. Some families stay with relatives initially. Others rent in the same suburb for school continuity.
You’ll need storage for furniture. Before demolition, disconnect utilities through your providers—they need about a week’s notice:
- AusNet Services or your electricity distributor
- Australian Gas Networks, or the gas provider
- Your local water retailer
Salvage anything with sentimental value and take photos. Notify Australia Post, banks, VEC, and others of your temporary address.
Typical costs: $450-$550/week rental, $150-$250/month storage.
Step 8: Demolition
Licensed demolition contractors must hold VBA licenses. According to WorkSafe Victoria, any Melbourne home built before 1990 likely contains asbestos. Licensed removal is mandatory under the Occupational Health and Safety Regulations 2017—no DIY allowed.
The contractor conducts pre-demolition asbestos inspection, safely removes asbestos to EPA-approved facilities, erects safety fencing, demolishes the structure over 2-5 days, removes waste, and hands back a clean site.
Asbestos removal adds $5,000-$15,000, depending on quantity and type.
Some materials can be salvaged—bricks, hardwood timber, doors, windows, and metal for recycling.
Typical costs: $15,000-$35,000 for standard demolition.
Step 9: Construction
Construction happens in five stages per standard VBA practice:
Stage 1: Site Works (2-4 weeks)
– Leveling, excavation, termite barriers, services trenching
Stage 2: Base/Frame (6-10 weeks)
– Foundation, frame erection, roof, and external walls begin
Stage 3: Lock-Up (6-8 weeks)
– Windows, doors, walls completed—home is weatherproof
Stage 4: Fixing/Fitout (8-12 weeks)
– Plumbing, electrical, insulation, plasterboard, painting, kitchens, bathrooms, flooring
Stage 5: Completion (2-4 weeks)
– Final inspections, landscaping, driveway, and cleaning
Your builder provides weekly progress updates. Mandatory inspections happen at footings, frame, waterproofing, and final stages per VBA requirements.
Timeline: 8-14 months for standard homes. Melbourne’s wet winters can add 2-4 weeks.
Step 10: Final Inspections and Moving In
The building surveyor conducts a final inspection confirming everything meets the National Construction Code. They issue an Occupancy Permit under the Building Act—you can’t legally move in without it.
Do a practical completion inspection with your builder. Note any defects—paint touch-ups, door adjustments, cleaning issues. Your builder fixes these before handover.
Under the Domestic Building Contracts Act 1995, builders must fix minor defects within 12 months and major structural issues within 6 years. Document everything with photos.
Arrange utility reconnections weeks before moving—some providers need advance notice for electricity, gas, water, and NBN.
Typical costs: $3,000-$8,000 connection fees plus moving costs.
Timeline Summary
- Planning & approvals: 3-6 months
- Demolition: 2-4 weeks
- Construction: 8-14 months
- Total: 12-20 months
Be prepared for potential delays. Melbourne weather, supply chain issues, council processing times, and variations you request mid-project all add time to the knock down rebuild process.
