Understanding the Cost of an Old Home Extension in Australia

Are you planning to extend your old home but are worried about the cost? 

 

Many homeowners find it challenging to determine the actual cost of an old home extension. Even with a clear budget of $250K, you might find the quote from the builder exceeding the budget, such as around $300K. 

 

Now, you’re asking yourself, “What is the actual cost of a home extension?” “Does the builder’s quote make sense?”  

 

The Cost of an Old Home Extension in Australia

 

According to service.com.au, the cost of an old home extension can vary depending on different factors: the size of the extension, materials used, and complexity of the work. 

 

For example, on average, an 80m2 ground floor extension for an old house ranges between $164,500 to $310,000. It highlights the need to consider different variables when calculating the cost of a home extension.

 

4 Factors that Affect the Cost of Old Home Extension

 

  • Size of the extension
  • Type of extension
  • Materials used
  • Complexity of work

 

Size of the Extension

 

The size is a significant factor that determines your home extension cost. A larger extension will need more materials and labour. The shape of the extension also influences its price, with complex shapes costing more than simple ones.

 

Type of Extension

 

There are different types of extensions: ground-floor, first-floor, and second-floor extensions. Their cost varies, with ground-floor extensions being the most affordable and second-floor being the most expensive.

 

Materials Used

 

The type of materials used for the extension also affects the cost. For instance, if you’re using premium materials like hardwood, the price will be higher than the alternative, such as treated pine. It also goes the same with the quality of finishes like tiles, paint, and fixtures, which may also impact the cost.

 

Complexity of Work

 

The complexity of the work also influences the cost of an old home extension. Extensive demolition, excavation, or structural work can affect the project’s price, and fixing the access issues, such as narrow driveways or steep slopes, will also add to the price.

 

How to Maximise Your Budget for an Old Home Extension

 

Now that you understand the factors affecting the cost of an old home extension, here’s how you can maximise your budget.

 

Plan and Design Carefully

 

To avoid unexpected costs, plan the design of your desired extension and include the cost and your budget. Consider the size, type, and materials you want to use, and prepare for potential challenges that could impact the cost.

 

Compare Quotes

 

Always get multiple quotes from different builders. It allows you to identify any price discrepancies and make an informed decision.

 

Prioritise

 

If you have a limited budget, prioritise the most critical aspects of the extension, such as increasing living space or adding an extra bedroom, and postpone any non-essential elements.

 

Be Flexible

 

Being flexible with your design and materials can help you save money. For instance, you can opt for a more affordable alternative, like treated pine, instead of expensive hardwood.

 

Conclusion

 

The cost of an old home extension in Australia varies depending on various factors. With careful planning, designing, and prioritising, you can maximise your budget and achieve your desired outcome.
