How does the renovation cost calculator work?
Tick each part of your renovation. The kitchen and bathrooms use the same prices as our price check, from What's The Damage's Gold Coast and Brisbane pages. The other jobs use What's The Damage's national prices for a full home renovation (October 2026), and the laundry uses Archicentre Australia's 2026 cost guide. The calculator adds up the low ends and the high ends.
It leaves out structural work, extensions and anything behind walls you can't see yet. Those are priced on site.
How much does a whole home renovation cost?
What's The Damage splits a full home renovation in Australia into three bands:
| Renovation | Price range | What it covers |
|---|---|---|
| Cosmetic refresh | $50,000 to $150,000 | Paint, floors, fixtures, landscaping. No structural changes |
| Mid-range | $150,000 to $350,000 | New kitchen and bathroom, rewiring, replumbing, some layout changes |
| Full gut | $350,000 to $550,000+ | Stripped to the frame, everything new |
What's The Damage, full home renovation cost in Australia, October 2026. Checked 27 October 2026.
For the Gold Coast, What's The Damage puts a full home renovation at $150,000 to $600,000, with $300,000 typical.
What does a renovation cost per m²?
Archicentre Australia's 2026 cost guide puts renovation work inside an existing house at $1,600 to $3,900 per m². That assumes the rooms are sound, need no structural work and are easy to get to. A new extension costs $2,700 to $5,100 per m² for the basic shell. Both include GST.
So 100 m² of renovation comes to about $160,000 to $390,000 by that guide.
