Tips for Your Deck & Pergola in New South Wales

Hardwood (Merbau, Spotted Gum) costs more upfront but lasts 25–40 years vs 10–15 for treated pine.

Always check local council setback and height regulations before building — non-compliant decks may need to be removed.

Composite decking eliminates annual oiling maintenance but can be 30–50% more expensive than timber.

Ensure adequate ventilation under the deck to prevent moisture build-up and termite attraction.

Request engineered drawings for elevated decks (over 1m) — this is a building code requirement in all states.

Frequently Asked Questions

How much does a deck or pergola cost in Sydney in 2026?

In Sydney, a deck or pergola project typically costs between $10,000 and $42,000 depending on size, materials and design. Most Sydney homeowners spend around $22,000 for a mid-range timber deck with a pergola, reflecting the higher labour and material costs in the Sydney market.

Do I need council approval for a deck or pergola in NSW?

In NSW, decks and pergolas may be exempt development if they meet certain size and height criteria under the State Environmental Planning Policy (Exempt and Complying Development Codes). Decks over 600mm above ground or within setback zones typically require a Complying Development Certificate or full DA.

What licence should a deck builder hold in NSW?

In NSW, any residential building work over $5,000 requires a contractor licence issued by NSW Fair Trading. Your deck builder should hold a General Building or Carpentry licence. Always verify their licence on the NSW Fair Trading online register and ensure they carry Home Building Compensation Fund cover for work over $20,000.

How do bushfire zones in NSW affect deck construction?

If your property is in a designated bushfire-prone area in NSW, your deck and pergola must comply with AS 3959 (Construction of Buildings in Bushfire-Prone Areas). This may require non-combustible materials, ember-proof screening underneath the deck and specific timber species rated for the applicable BAL level.

What is the best decking material for the Sydney climate?

For the Sydney coastal climate, Spotted Gum and Blackbutt are excellent native hardwood choices that resist moisture and salt air. If you prefer low maintenance, composite decking handles Sydney's variable weather without annual oiling. Avoid treated pine in exposed coastal areas as it deteriorates faster.
