Brisbane spent over $880 million on home improvements.

Design dilemmas are the most commonly discussed renovation topic among home improvers
In recent years Australia’s property market has taken a hit from the rising costs of both interest rate rises and inflation. This has made many Australians reluctant to purchase property. In fact, new home sales have dropped by an eye-watering 42 per cent. With this in mind, people are likely considering ways to make the most of their current spaces, as opposed to getting onto the property ladder.
Home renovation can be a fantastic way to add value to your property and improve the overall aesthetics of your home. However, it can be more challenging than just a lick of paint and many home renovation projects are costly, especially for more significant home improvements such as extensions or an alteration.
With many falling in love with postcodes over properties, as time moves on, the conversation about home improvement starts and individuals are left looking at decisions between extending the home or moving completely.
With that in mind, we have investigated where in Australia spends the most on home renovations as well as looking at what types of home improvements are discussed most often.
The value of renovations and alterations in Australia’s top 20 cities and regions
The city that spent the most in home renovations and alterations in the last year is revealed to be Brisbane, Queensland, with a spend of over $880 million on home improvements. The cost of living in Brisbane is significantly higher than in Perth (who are spending the least on home renovations at just over $19 million) so it's perhaps surprising that so many are looking to make home improvements, as opposed to moving to a more affordable area.
When looking at these costs in relation to population size, the story changes. The City of Greater Geelong, Victoria, comes out as the biggest spender by population size with $725 per person spent on home improvements. The Sunshine Coast has the second largest spend per person, at $641.
Biggest spenders Brisbane has a total cost of $402 per person spent on home improvements - the 8th highest of all cities.
Data has been collected at the LGA level for each city and region within each state and territory, looking at building approvals in Australia, published by the Australian Bureau of statistics.
How much does each extension/conversion cost?
When looking at the highest renovation cost, a two-storey extension will set you back the most, costing an average of $504,000.
Basement conversions are the second most expensive renovation cost, at $375,000. The higher cost is due to the fact that contractors need to be extra careful not to damage the property above the basement, which.typically adds to the time it takes to complete the job.
The cheapest home improvement was found to be a new sunroom, costing $17,500. Coming in at $486,500 cheaper than the highest renovation cost of a two-storey extension, it could be a money saving alternative if you are looking for a little extra space but don't have the funds for a full extension.
Whilst renovation expenses may seem costly at a glance, the return on your investment is usually seen when it comes to selling your property, or at the post-remodel property valuation. However, while renovation can be profitable, it's important to do your own homework about whether this is the right investment for you and your home.
