The Ultimate Guide to House Extension Costs | 2024

Feeling that your home is too small or outdated? You may be facing the difficult decision between choosing to extend or sell your current home.

House extensions are an excellent way to transform the look and functionality of your home, as well as adding value to your property and to your lifestyle. Whilst an extension is a costly project, it can actually be more cost-effective than selling your home and purchasing a new one.

The transactional expenses of moving house add up quickly.

The main selling costs include real estate agents commission, auction fees, display furniture, professional photography and conveyancers costs.

While the largest cost will be the Stamp Duty payable on the purchase of your new property, currently around 5.5% in Victoria. On top of all this are the costs for removalists, mortgage establishment fees and the inconvenience of moving house! On the median priced home in Melbourne these fees could be up to $70,000. That equates to fees and taxes that you could have spent on renovating and extending your home!

How much does a home extension cost?

The cost of a house extension can vary greatly depending on the size, dimensions, permit requirements, and quality of materials used.

Generally, prices for an extension project start at $2,000-$3,000 per square metre with prices increasing further depending on the scope and complexity of the project. For example, a second-story extension can increase the cost of an extension by 50% per square metre compared to a ground-story renovation.

Identifying and then prioritising your needs and desires for a house extension is the first step to kickstarting your renovation adventure and avoiding unexpected financial strain.
