A knock-down rebuild is a home improvement strategy where an existing house is demolished and a new one is built in its place.
This process allows homeowners to create a modern, customised living space without changing their address. It’s an increasingly popular option for those who love their location but need to find their current home updated, too small, or no longer suitable for their needs.
Knock-down rebuilds offer a fresh start on familiar ground, combining the best of both worlds – a brand-new home in an established neighbourhood.
Benefits of choosing a knock-down rebuild over buying new
- Keep your current location: Stay in your familiar neighbourhood, maintaining connections to schools, work, and community. Preserve relationships with neighbours and local businesses while improving your living space.
- Avoid substantial property purchase costs: Sidestep expenses like real estate agent fees and stamp duty associated with buying a new property. Redirect these savings into your new home's features.
- Custom design for your lifestyle: Create a home that perfectly fits your needs and preferences. Maximize your block's potential, taking advantage of orientation for natural light and energy efficiency.
- Cost-effective compared to major renovations: Avoid unexpected issues and budget blowouts common in renovations. Benefit from modern building standards throughout the entire home.
- Improved energy efficiency: Build to higher energy efficiency standards with better insulation and energy-efficient appliances. Enjoy a more comfortable living environment while potentially reducing long-term running costs.
- No compromises on home features: Control every aspect of your new home's design, from layout to finishes. Move into a home perfectly suited to your taste without need for immediate updates.

Understanding the Knock Down Rebuild Process
The knock-down rebuild process involves several key stages, each crucial to the success of your project. Understanding these steps will help you navigate the journey smoothly and set realistic expectations.
Initial assessment and feasibility study
Before demolishing your old home, it’s essential to determine if a knock-down rebuild is the right choice. This stage involves a comprehensive evaluation of your property and goals:
- Evaluate your current property's condition and value: Assess the structural integrity, age, and potential issues of your existing home.
- Assess local zoning laws and building restrictions: Research council regulations, heritage overlays, and neighbourhood character guidelines that might affect your rebuild.
- Estimate potential costs and compare with alternatives: Calculate the total project cost, including demolition, construction, and temporary accommodation. Compare this with renovation costs or the price of buying a new property.
- Consider site-specific factors: Analyze soil quality, land slope, access to utilities, and potential environmental issues that could impact construction.
Design and planning phase
- Collaborate with architects or designers: Work with professionals to create a home that meets your needs and complies with local regulations.
- Consider your lifestyle needs: Think about your current and future requirements, such as the number of bedrooms, home office space, or accessibility features.
- Explore different layouts and features: Discuss various floor plans, room orientations, and special features like energy-efficient designs or smart home technology.
- Balance your wish list with your budget: Prioritize your must-haves and nice-to-haves to ensure your design aligns with your financial constraints.
- Create detailed construction drawings: Develop comprehensive plans and specifications that will guide the building process and help you get accurate quotes from builders.
Obtaining necessary permits and approvals
- Submit plans to your local council: Present your detailed plans for review and approval. This may involve multiple rounds of submission and adjustment.
- Obtain demolition permits: Secure the necessary permissions to safely and legally demolish your existing structure.
- Secure building permits for the new construction: Ensure your new home design complies with all local building codes and standards.
- Address heritage or environmental considerations: If applicable, work with relevant authorities to meet any special requirements related to heritage preservation or environmental protection.
- Arrange for utility disconnections and reconnections: Coordinate with service providers to safely disconnect utilities before demolition and plan for reconnection during construction.
This stage can be time-consuming and complex. Working with experienced professionals who understand local regulations can help streamline the process and avoid potential delays.
Demolition process
- Prepare the site: Remove personal belongings, valuable fixtures, and any items you wish to salvage or reuse.
- Disconnect and cap off utilities: Ensure all services like electricity, gas, water, and sewage are safely disconnected and sealed.
- Remove hazardous materials: Conduct asbestos inspections if necessary and arrange for the safe removal of any hazardous substances.
- Demolish the existing structure: Use appropriate machinery and techniques to carefully demolish the building, minimizing impact on neighbouring properties.
- Clear the site: Remove all debris, level the ground, and prepare the site for new construction.
- Conduct any necessary soil testing or remediation: Address any soil contamination or structural issues before beginning new construction.
Construction phase
- Site preparation and foundation work: Level the site, lay the foundation, and install underground plumbing and electrical systems.
- Framing and structural elements: Erect the skeleton of your home, including walls, floors, and roof trusses.
- Roofing and exterior finishes: Install roofing materials, windows, doors, and exterior cladding to make the structure weathertight.
- Interior construction: Rough in plumbing, electrical, and HVAC systems. Install insulation and drywall.
- Flooring, cabinetry, and finishes: Lay flooring, install kitchen and bathroom fixtures, and apply paint and other finishes.

- Documentation handover: Receive all necessary paperwork, including warranties, manuals, and maintenance schedules for your new home and its systems.
- Key handover: Finally, receive the keys to your brand-new, custom-built home.
Costs Associated with Knock-Down Rebuilds
Understanding the costs involved in a knock-down rebuild project is crucial for proper budgeting and decision-making. Let’s break down the various aspects of pricing to give you a clearer picture of what to expect and how to plan financially for your project.
Final inspections and handover
- Location: Costs are higher in cities than in regional areas due to land values and labour rates.
- Site conditions: Sloped blocks or poor soil can increase foundation and construction costs.
- Home size and design: Larger homes and complex designs cost more.
- Materials and finishes: Premium options increase overall costs.
- Energy efficiency: Features like double-glazing or solar panels add upfront costs but save money long-term.
- Demolition complexity: Asbestos or hazardous materials removal increases costs.
- Council requirements: Fees and building codes vary by location, affecting budget.
Breakdown of typical expenses
Pre-construction costs:
- Design and architectural fees: This can range from 3-10% of your total budget, depending on the complexity of your design and the level of service provided.
- Council application fees and planning permits: These vary by council but can run into thousands of dollars.
- Soil and contour surveys: Essential for proper foundation design, these typically cost between $800-$2,000.
Demolition costs:
- Disconnection of utilities: This is usually a few hundred dollars per service.
- Asbestos removal (if necessary): Can range from $25-$50 per square metre for removal.
- Physical demolition and site clearing: Typically ranges from $10,000-$30,000 for an average-sized home.
Construction costs:
- Site preparation and foundation work: This can vary widely based on site conditions but often accounts for 10-15% of the build cost.
- Building materials and labour: The bulk of your budget, often 50-60% of the total cost.
- Plumbing, electrical, and HVAC systems: Usually account for about 20-25% of the build cost.
- Interior finishes and fixtures: These can vary widely based on your choices but often represent 15-20% of the build cost.
Additional costs:
- Temporary accommodation during the rebuild: This can add several thousand dollars to your budget, depending on the duration of the build.
- Landscaping and outdoor features: Often overlooked, this can add 5-10% to your total budget.
- Contingency fund: It's wise to set aside 10-20% of your total budget for unexpected expenses or changes.
Using a knock-down rebuild cost calculator
- Input details such as location, house size, and desired features. Be as specific as possible for more accurate results.
- The calculator provides a rough estimate based on average costs in your area. This can give you a ballpark figure to start your budgeting process.
- Remember, these tools offer ballpark figures and shouldn't replace a detailed quote from a builder. They often don't account for site-specific challenges or unique design elements.
- Use multiple calculators to get a range of estimates for a more comprehensive view. This can help you understand the potential cost variability.
These quotes should break down costs by category, allowing you to see where your money is being allocated and where you might be able to make adjustments if necessary.
Knock-down rebuild price guide for different home sizes and styles
- Small home (up to 150m²): $300,000 - $500,000 Suitable for couples or small families, these homes typically include 2-3 bedrooms and basic amenities.
- Medium home (150-250m²): $500,000 - $800,000 Ideal for growing families, these homes often feature 3-4 bedrooms, multiple living areas, and more extensive outdoor spaces.
- Large home (250m²+): $800,000 - $1.5 million+ Suited for large families or those desiring luxurious space, these homes can include 4+ bedrooms, multiple bathrooms, expansive living areas, and high-end finishes.
Style considerations:
- Single-storey homes are generally less expensive than double-storey designs due to simpler construction and less structural support required.
- Complex roof designs or unusual architectural features can increase costs due to additional materials and labour.
- Open-plan layouts might cost less due to fewer internal walls but may require more structural support, potentially offsetting some savings.
- Traditional styles might be more cost-effective due to readily available materials and construction techniques, while ultra-modern or unique designs could increase costs.
A well-planned knock-down rebuild can offer excellent value for money compared to buying a new home or extensively renovating an older property. It allows you to create a home that perfectly suits your needs and lifestyle, potentially increasing your property’s value and your long-term satisfaction.
WANT AN INSTANT ESTIMATE FOR YOUR PROJECT?
Timeline: How Long Does a Knock-Down Rebuild Take?
While the duration can vary significantly based on several factors, understanding the typical timeline and what influences it can help you plan effectively.
Factors influencing project duration
- Project scope and complexity: Naturally, larger or more intricate designs will take longer to complete. A simple single-storey home might be finished more quickly than a multi-level house with custom features.
- Local council processes: The time required for council approvals can vary widely depending on your location and the complexity of your plans. Some councils may process applications within a few weeks, while others might take several months.
- Weather conditions: Extreme weather events or prolonged periods of unfavourable conditions can cause delays, particularly during the early stages of construction.
- Site conditions: Unexpected issues like poor soil quality or the discovery of rock formations can lead to delays in site preparation and foundation work.
- Availability of materials and labour: Shortages in building materials or skilled tradespeople can extend project timelines. This factor can be particularly relevant during peak construction periods or in the aftermath of natural disasters.
- Changes to plans: Modifications to the design once construction has begun can significantly impact the timeline. It's crucial to finalise plans as much as possible before commencing work.
Typical timeframes for each phase
- Planning and design: 2-6 months This phase includes initial consultations, creating and refining designs, and preparing documentation for council submission. The duration can vary based on how quickly you make decisions and the complexity of your design.
- Council approval: 1-6 months The time for council approval can vary significantly depending on your location and the complexity of your application. Some straightforward applications might be approved in a matter of weeks, while more complex ones could take several months.
- Demolition: 1-2 weeks The actual demolition of your existing home is usually a quick process, often completed within a week or two. However, preparing for demolition, including disconnecting utilities and removing hazardous materials like asbestos, can add to this timeframe.
- Construction: 6-12 months The construction phase is typically the longest part of the process. A simple, single-storey home might be built in 6-8 months, while a larger or more complex home could take 10-12 months or more. This phase includes everything from laying the foundation to final touches and landscaping.
- Final inspections and handover: 2-4 weeks Once construction is complete, final inspections are conducted, and any identified issues are addressed before you can move in.
Tips for managing and potentially reducing project time
- Plan thoroughly: Invest time upfront in detailed planning. The more decisions you can make before construction begins, the smoother the process will be.
- Choose an experienced builder: A builder with a track record of successful knock-down rebuilds will likely be more efficient and better at anticipating and solving problems.
- Be decisive: Quick decision-making when selecting fixtures, finishes, and addressing any issues that arise can help prevent delays.
- Consider a project manager: If you're not confident managing the process yourself, hiring a project manager can help keep everything on track.
