    How Much Does a Knock Down Rebuild Cost?

    April 19, 2023  

    Have you ever looked at your outdated home and wished you could start from scratch? The knock down rebuild process might just be the solution you’ve been looking for! But before you start planning out your brand-new dream home, let’s talk about the cost. In this article, we’ll explore the ins and outs of knock down rebuilds and their potential costs to help you make an informed decision about this exciting opportunity.

    Average Cost To Rebuild A House In Australia Compared To Sydney

    The cost of the rebuild process in Australia can vary widely depending on location, size, materials, local zoning laws, and other factors.

    The average demolition costs vary from state to state but can range from $12,000 to $40,000. A demolition company is most likely to use a cost-per-square-metre system; research shows that Sydney homeowners will be spending anywhere between $53-$114 per square metre.

    The next step is to look at the cost of rebuilding on your block. The average cost to rebuild a house in Australia is around $1,900 per square metre, with the average cost in Sydney currently at approximately  $2,500 per square metre. This is a general rule of thumb, however it’s important to note that your preferences, design complexities and specific needs are also factored into the cost of your rebuild.

    It’s important to keep these cost differences in mind when considering a knock down rebuild project in Sydney.

    A Financial Comparison Between Knockdown Rebuilds & Renovations

    When it comes to improving your home, you may be torn between a knock down rebuild and a home renovation.

    While a major renovation may seem like a more affordable option, it’s important to consider the potential hidden costs that may arise during the renovation process, such as structural changes, unforeseen issues, or old electrical cabling.

    In many cases, a knock down rebuild may actually be a more cost-effective option, as it allows you to start from scratch with a new home and energy efficient design.

    The final question is: Is it cheaper to knock down and rebuild or renovate? Ultimately, whether it’s cheaper to  knock down rebuild or to renovate depends on your specific circumstances, such as the age and condition of your existing property, your budget, selecting new homes builder and your design goals. However, by carefully weighing the potential costs and benefits of each option, you can make an informed decision that’s right for you and your family.

    It’s worth mentioning that with land value rising to near-unprecedented costs, it may be much more cost-effective in the long run to go through the knockdown rebuild process.


    5 Ways to Save Money During the Knockdown Rebuild Process

    While a knock down rebuild can be more expensive than a renovation, there are ways to save money during the process without sacrificing quality or design.

    Let’s explore five practical tips to help you stay within budget and make the most of your knockdown rebuild project.

    • Consider the size and complexity of your new house design, as simpler and more efficient plans can be less expensive to build
    • Opt for cost effective new materials that are still durable and high-quality, such as concrete blocks or brick
    • Plan ahead for potential additional factors and costs, such as site preparation, landscaping, and a demolition permit, so you can budget accordingly
    • Consider taking on some of the project yourself, such as the landscaping, if you have the skills and time to do so


    Is a knockdown rebuild worth the cost? Pros and Cons

    When considering a knockdown rebuild, it’s important to weigh up the potential benefits and drawbacks to determine whether it’s worth the cost.

    Let’s explore three pros and cons of a knockdown rebuild to help you make an informed decision.


    • A knockdown rebuild allows you to start fresh with a new house that meets your particular needs and preferences
    • A new house built to modern standards can be more energy efficient, saving you money on utility bills in the long run
    • Knockdown rebuilds can also increase the value of your property, making it a worthwhile investment


    • A knockdown rebuild can be more expensive than other home renovation options, which may be a consideration for those on a tight budget
    • The knockdown rebuild process can be lengthy and disruptive, requiring you to find alternative accommodation during construction
    • A knockdown rebuild may also require additional expenses, such as site preparation, a demolition permit and approval fees

    While a knockdown rebuild can be a significant investment, the potential benefits, such as a custom-designed home and increased property value, make it a worthwhile option for many Sydney homeowners.

    Do You Pay Stamp Duty on Knock Down Rebuilds?

    If you’re planning a knock down rebuild, you may be wondering if you’ll be required to pay stamp duty costs on the new construction.

    The good news is that in most cases, you won’t have to pay stamp duty on the construction costs themselves, as long as you have lived in the existing house for at least 12 months prior to the knocking down and rebuilding.

    You may need to pay stamp duty on the land component of your project if you buy a property to immediately knock it down and rebuild.

    It’s important to consult with your local council, a financial advisor, or knockdown rebuild specialists to determine your specific stamp duty requirements and eligibility for any exemptions or concessions.


    6 Additional Costs that Apply To A Knock Down Rebuild In The State of New South Wales

    While a knock down rebuild can be an exciting way to create your dream home, it’s important to consider all the potential costs involved in the entire process.

    Let’s explore six additional rebuild costs that you may not have considered, but should be aware of, before starting your project.

    1. Legal costs

    You may need to obtain permits, contracts, and other legal documentation, which can add to your overall legal expenses, particularly if you are purchasing a new property specifically for the knock down rebuild costs. We recommend consulting with a lawyer or legal professional to determine your specific legal requirements and budget accordingly.

    2. Demolition costs

    The demolition costs can vary depending on the size and complexity of the existing house, as well as the local council regulations and requirements for demolition and removal of debris. Discoveries of asbestos, for example, can add unexpected costs to the demolition budget. Obtain quotes from new house builders in Sydney to get a clearer idea of the costs involved.

    3. Rubbish Removal costs

    When undertaking a knock down rebuild project, you’ll likely generate a significant amount of debris and waste from the demolition crew that will need to be removed from the vacant land. Depending on the volume of waste and the local council requirements for disposal, this can add to your overall costs.

    4. Certificate 73

    Certificate 73 is a legal document that certifies that your new construction complies with all relevant codes and regulations. It’s a legal requirement for all new builds and renovations. The cost of obtaining a Certificate 73 can vary depending on the size and complexity of your project.

    5. Trees

    Trees may need to be removed or pruned to allow for the demolition and construction process, and this can add to your overall costs. Additionally, if you have trees that are protected by local council regulations, you may need to obtain permits and pay fees to remove or prune them.

    6. Construction loan

    You may need to take out a construction loan to cover the costs of the project. Construction loans can have higher interest rates and fees than regular home loans, and there may be additional fees for progress payments and loan administration. Most lenders will have different options, so we recommend you compare them and factor in these costs when budgeting.
