How the estimate works

What goes into the number.

We start with a per-m² merbau rate and adjust by your chosen material, area and complexity. Add-ons like pergola or balustrade stack on top.

  • Deck area and height above ground.
  • Material — composite is most expensive per m² but lowest maintenance.
  • Whether engineering and council approval are required (decks over 1 m typically need approval).
  • Stairs, balustrades and roofing over the deck.

Frequently asked questions

Do I need council approval for a deck?

Most states require approval for decks above 1 m off the ground or with structural impact. Low-level decks attached to a dwelling can often be built as exempt or complying development.

Hardwood vs composite — which is better?

Hardwood looks better and ages naturally but needs oiling every 1–2 years. Composite has higher upfront cost but minimal maintenance and a long, predictable lifespan.
