Decking
A deck turns an unused corner of a yard into somewhere you actually sit. Timber brings warmth and can be restained to suit, while composite boards cost more upfront and need very little attention afterwards.
Pricing guide: How much does a deck cost?
Roughly $200 to $350 per square metre for treated pine, more for hardwood or composite. Height, footings and balustrades affect the figure significantly.
Why homeowners choose it

Hiring guide
Questions worth asking before you commit to a contractor.
Ask to see it, not just take their word for it. Insurance protects your property if something goes wrong on site.
Site preparation, disposal of old material, and any council permits can be included or charged separately — get it in writing before you compare quotes.
Some contractors do the work themselves; others subcontract parts of it. Neither is wrong, but you should know who is doing your job.
Old concrete, tree roots or drainage issues are common surprises. Ask how a change of scope gets costed before it happens, not after.
Materials usually carry a manufacturer's warranty. Ask specifically about the contractor's own workmanship warranty too.
Frequently asked questions
How much does a deck cost?
Roughly $200 to $350 per square metre for treated pine, more for hardwood or composite. Height, footings and balustrades affect the figure significantly.
Do I need a permit?
In Victoria a building permit is generally required once a deck is more than 800mm above ground. Your contractor can confirm for your site.
Timber or composite?
Timber is cheaper upfront and can be recoloured, but needs oiling every year or two. Composite costs more initially and needs little beyond washing.
How long does a deck last?
A well-built hardwood deck lasts 20 years or more with maintenance. Composite is usually warranted for 15 to 25 years.
