How much does decking cost in Sydney?
A timber deck is priced per square metre for the frame and the boards together. In Sydney a built hardwood deck runs $160 to $280 per square metre for the structure and boards, with the timber itself a big part of that. Premium hardwoods and raised or multi-level decks push toward the top.
What it costs
| Job | Typical Sydney range | What it covers |
|---|---|---|
| Decking build (frame plus boards) | $160 to $280 per m2 | Substructure and boards, oiling extra |
| Hardwood boards (supply) | $90 to $160 per m2 | Spotted gum, merbau, blackbutt |
| Carpenter (labour) | $95 to $145 per hr | Decking, pergolas and screens |
| Pergola over a deck, small 3x3m | $4,500 to $10,000 | Timber, supplied and built |
What affects the price
- Height. A ground-level deck is far cheaper than a raised deck that needs posts, bearers and balustrade.
- Timber. Treated pine is the budget option; spotted gum and merbau cost more but last longer in Sydney sun.
- Shape. Curves, steps and multiple levels add carpentry time.
- Finish. Oiling or staining is usually quoted on top of the build rate.
Common questions
How much does a deck cost per square metre in Sydney?
A built hardwood deck is typically $160 to $280 per square metre including the frame and boards. A 20 square metre deck is therefore roughly $3,200 to $5,600 before extras like balustrade or stairs.
Is composite decking worth it?
Composite costs more up front than treated pine but needs no oiling and resists Sydney weather, so many homeowners pick it for low-maintenance decks. Hardwood remains the premium natural look.
Do I need approval for a deck?
Low decks under a set height are often exempt, but raised decks and those attached to the house can need approval. Your landscaper or a certifier will confirm for your site.
