How much does a house extension cost in Wollongong?
The cost of a house extension depends on the size, complexity, and type of addition. On average, ground-floor extensions in Wollongong can range from $2,000 to $4,000 per square metre. Costs can increase with structural work, premium finishes, or difficult site access. A detailed quote from a local builder is essential to plan accurately.
Do I need council approval for a house extension or addition?
Yes, most extensions and additions require local council approval or a complying development certificate. This ensures the project meets zoning, structural, and environmental regulations. A builder with experience in the area can help manage the approval process and work with designers or certifiers to move things along smoothly.
What’s the difference between a house extension and an addition?
A house extension typically means building outward—adding rooms or living space at ground level. An addition usually refers to adding space vertically, such as a second-storey or attic conversion. Both add usable area to your home, and the choice depends on your block size, layout, and goals.
