Why Extend Your Property?

There are many reasons why you might consider a property extension in the Northern Rivers. Here are just a few of them:


  • It can be much more economical than moving
  • It can enhance the value of your property
  • It can give you the space in which to build a granny flat – which could be a tidy little earner if you put it on Airbnb
  • It can give you space for your work or hobbies

  • What types of home extensions are available?

    Home extensions can take many forms depending on your space and goals. Common types include rear extensions to expand living areas, second-storey additions for extra bedrooms or bathrooms, and side extensions to maximise narrow blocks. Other options include garage conversions and adding alfresco or outdoor entertaining areas. The right choice depends on your property layout, council regulations and how you use your space.

  • Do I need council approval for a home extension?

    In most cases, yes, you’ll need council approval before starting a home extension. The requirements vary based on your local area, the size and scope of the project, and how close the extension is to neighbouring boundaries. An architect or draftsman can help prepare the necessary plans and submit them to council on your behalf. It’s important to check early on to avoid delays or non-compliance issues.
