If your current house no longer fits your lifestyle, but you love the location, knock down rebuild (KDR) might be the perfect solution. Rather than moving or renovating an old structure, many Australians are choosing to demolish and rebuild from scratch, designing a brand-new home that suits their vision, family, and budget.
What Is a Knock Down Rebuild?
A knock down rebuild is the process of demolishing your existing home and constructing a new one on the same plot of land. It’s a popular alternative to moving, offering the best of both worlds: a brand-new home without leaving the suburb you love.
Benefits of a Knock Down Rebuild
1. Stay in Your Preferred Location
Forget the stress of changing schools, commutes, or local amenities. KDR allows you to stay in your ideal location while upgrading your lifestyle.
2. Better Value Than Renovating
Renovations often come with hidden costs and compromises. With a knockdown rebuild, you get a brand-new home with modern fittings, better energy efficiency, and less ongoing maintenance, often for the same or less cost than a large renovation.
3. Custom Home Design
Work with your builder to create a home that suits your needs—from open-plan living and extra bedrooms to outdoor entertaining areas and smart technology.
4. Improved Energy Efficiency
New homes must comply with current energy efficiency standards, meaning you can enjoy lower energy bills and a reduced environmental footprint.
Knock Down Rebuild vs Renovation: Which One Wins?
| Feature | Renovation | Knock Down Rebuild |
| Customization | Limited | Full control |
| Cost predictability | Less predictable | Fixed price contracts available |
| Energy efficiency | Difficult to improve | Meets new standards |
| Timeline | Often delayed | Streamlined process |
| Long-term value | Moderate | High resale potential |
The Knock Down Rebuild Process
- Site Assessment & Feasibility
Your builder will inspect your block to assess zoning, slope, access, and council regulations. - Home Design & Quote
Choose a standard or custom design tailored to your lifestyle. Builders will then provide a detailed quote. - Demolition
After approvals, the existing house is demolished. Reputable builders handle demolition permits and waste removal. - Construction
Your new home is built from the ground up, usually within 6–12 months. - Move-In
Once the final inspection is complete, you’ll receive the keys to your brand-new home.
Is Your Property Suitable for a Knock Down Rebuild?
While most suburban blocks are suitable, a few factors can affect your eligibility:
- Heritage overlays or zoning restrictions
- Block slope or access difficulties
- Easements and council requirements
A professional builder experienced in knockdown rebuilds in Sydney or other metro areas will help you navigate these hurdles.
How Much Does a Knock Down Rebuild Cost?
On average, knock down rebuild costs in Australia range from $250,000 to $800,000+, depending on:
- Home size and design
- Site conditions and slope
- Demolition and clearance
- Custom features and finishes
Reputable builders offer fixed-price contracts, so you avoid budget blowouts.
Why Choose Knock Down Rebuild Over Buying New Land?
Land in established suburbs is scarce and expensive. KDR lets you access premium locations without the hefty price tag of buying new land, especially in high-demand areas like Sydney, Melbourne, and Brisbane.
Work With a Trusted Knock Down Rebuild Specialist
Not all builders are equal. Choose a company with:

Final Thoughts
If you’re sitting on valuable land but your house is outdated, a knock down rebuild gives you the freedom to start fresh without starting over somewhere else. It’s the modern path to luxury, flexibility, and long-term value—right where you already live.
