The decision to knock down a building is not a small undertaking. It’s a decision that usually comes after significant time weighing up the pros and cons of renovating what you already have or whether you’re better off starting again from scratch with a clean slate.
The biggest factor in the decision is usually the financial implications of the two different options. For example, if you are currently living in the property, this adds another level of complexity to your decision because you need to be prepared to find somewhere else to live throughout the knock-down rebuild process. However, a knock-down rebuild can potentially save you money as you have the ability to create a home with exactly the layout and functions you want, rather than adapting an existing house, which can often end up the more expensive option, rather than starting fresh.
Each project is unique, so it is not possible to quote exact figures, but if it’s a question of examining the alternatives and what they might cost, we can come up with a general idea of what makes the most financial sense. Then you can do the tweaking to make it relevant to your real-life situation and crunch the numbers.
Defining The Three Pillars of KDRB Cost: Demolition, Site, Rebuild
Demolition
The best we can do here is ballpark prices. How much does demolition cost? It depends on the size of the building, the accessibility and the method of construction, plus any aggravating factors such as the presence of asbestos, which might not be discovered until the demolition is underway and then bring it to a halt while health and safety measures are put in place.
Demolition in these circumstances must be done with care. The site already has electricity, water and drainage, maybe gas and possibly broadband, so it would make sense to preserve these as far as possible.
Site Costs Specific to Geelong
Geelong is an urban area, so any knockdown rebuild needs to consider local authority approval and consideration of your neighbours to ensure the process goes smoothly. There are potential issues, such as soil reports (because you need to know what exactly you’re building your house on top of), perhaps slopes that can make the construction process difficult and should be addressed in advance. And there are those services, AKA utilities, you need to be across.
Ballpark for the demolition phase? As of late 2025, $10,000 to $40,000, depending on the factors above.
Rebuild Construction Costs per Square Metre
Again, it all depends on what you’re building: how big, how intricate, how luxurious. In addition to the building itself, you’re going to have to fit it out (bathroom and kitchen, heating, air conditioning and so on). Most people will also go for new furniture, apart from a few favourite pieces that may have sentimental value. These things are not strictly speaking part of the budget for building the house, but they are going to affect the overall cost of the move.
According to the Australian Bureau of Statistics, the average cost of building a house in Victoria in 2022-23 was more than $412,000. Whereas, in 2025, the average cost of a new home build across Australia was $492,410.
If you want to think in terms of a worst-case scenario, then, with the demolition cost built in, you could be looking at $450,000 plus any extra costs caused by site complications.
Budgets and Flexibility
There is no avoiding the fact: getting a new home can be an expensive investment. But if your initial ideas come back from the builders with an estimate higher than you were expecting, you can discuss ways of reducing it. Your home is often the most significant investment you will make in your lifetime, and it’s important to work with a builder who will provide realistic, down-to-earth estimates so that you can build a house you’re proud to call your home, whilst sticking within your budget.
Saving a couple of hundred here and there by using cheaper materials is one way of doing it, but if you want to reduce the price, sometimes you must simply be honest with yourself: do you really need that big farmhouse-style kitchen or could half of it be the bathroom and therefore you can still have the spare room you’ve always wanted? If you find this hard to do in a disciplined way, ask your builder for some practical cost-saving options. They can help you to take a step back from your project and see what is essential and what is more of a nice-to-have addition that could be pumping up your price point.
Hidden Costs & Essential Budget
In addition to issues such as soil and slopes, there may be permits to apply for and pay for, which may not be expensive, but it all adds up. On the subject of slopes, there could be some landscaping to do, which can involve paying an expert for their ideas, if you don’t take it upon yourself to use your creativity, and, if you do, assuming your plans are regarded by the council and the builders as practical and safe.
Turning a troublesome piece of land from a problem into a positive is certainly possible, but it can involve preparatory work after the demolition as well as dressing up once the construction work has been completed. You may have to add a few thousand to your bottom line to get the job done.
Then there is your temporary accommodation, unless you are fortunate enough to have friends or family willing to put you up for nothing. You’ll have an estimated timeline, but it would be best to find somewhere that would let you extend your stay if this changes.
