What Has Been The Average Estimate?
If you’ve been following the data and information provided by us, you would know that any home extension costs at least around $100,000. It can even reach $1,000,000 or more and even the multi-million dollar mark.
The given flow chart, once again, represents the percentage of majority and minority out of the 100% traffic to the calculator. Accordingly:
Most Home Renovations, around 91% of the total estimations, are under $300,000.
9% of projects are in the $300,000 to $500,000 range. It is assumed that most high-end double-story extensions and renovations fall under this category.
From the above-given data, we can see that the majority of smaller type extensions and renovation projects cost between $100,000 to $300,000.
A notable 21% also fall below the $100,000 mark for basic type renovation works. Those might be for ensuite and bathroom renovations.
However, home extension costs are fairly diverse, ranging from the $100,000 to the $300,000 mark.
What Is The Average Size Of Extension Work?
From the collected data, the majority of extensions ranged from 20 m2 to 80 m2 in the cost-effective range. Around 17% of queries hit the requirement above 100 m2 to 150 m2.
Around 4% of queries have been for renovation only type work. This shows that people are using the calculator for mainly extension of around 20 to 80 square metres as an average requirement. Which fits the bill of the average home sizes in Australia.
Determining The Home Extension Cost – Speculations From Data
If we correlate them to the home extension estimation chart, we could -speculate- that 100m2 to 150m2 extensions cost around $300,000 to $500,000.
Meanwhile, most extensions cost around $150,000 to $500,000. It helps us drive out the average cost.

20 m2 extension costed around $200,000
40 m2 extension costs around $$300,000
60 m2 extension costs around $400,000
80 m2 extension cost around $500,000
These are not strict or hard-imposed data, just something collected from the charts.

In this context, going up means the second storey or double storey extensions. Meanwhile, going out is a ground-level extensions or renovations works.
It can been seen that most people are using the calculator for renovation only works or for lower level ground floor extensions (72%).
What is surprising is the 28% of people are using the calculator for larger first floor or double storey extensions. This is exciting as going up has the best visual impact on the streetscape and shows users are looking to not only increase the size but also improve the look of their existing home.
