How much does a deck cost to build (QLD Australia)?

Asking how much a deck will cost to build is a common question and one that has many variables attached to arrive at an accurate cost. Pricing varies based on the style and inclusions you want and it will also alter based on location. This price guide is based on South East Queensland parts and materials as well as labour costs. Pricing may vary in other parts of Queensland and across Australia.

Things that can vary price are based on the type of deck you want. Here are a few elements you will need to consider:

  • What material will you build your deck out of – treated pine, hardwood (merbau, ironbark, blackbutt etc) or composite decking (Ecodeck, Modwood)
  • Where is your deck going to be positioned? Is it low to the ground, slightly elevated with a few steps for access or fully elevated with a staircase taking you to a second story?
  • Do you want to include features such as enclosed deck screening or edging? Planter boxes? Feature bench seating? Privacy screen panels? Feature edging? Handrails?

For a standard deck that is made from Merbau, low or slightly raised from the ground you can get a rough price by measuring the space you want to deck and multiply the width by the height. This will give you a total square metre tally and cost per square metre can be based on $260-$290 per m2.


10m long alfresco deck span x 3m wide (or deep) alfresco deck span = 30 m2

30 x $260 = $7,800

30 x $290 = $8,700

This estimated cost includes merbau hardwood decking panels, joists, bearers, materials used to build and fasten, labour, QBCC insurance coverage. Higher end pricing can also include handrails and balustrades.

A typical timeline on this type of job would fall between 1 and 2 weeks depending on site access, material availability and weather conditions.

Clients often choose to adjust building material quality to help fall into their chosen budget as well as adding handrails, stair access and often feature elements for entertaining purposes.
