How much does a deck or pergola cost in Brisbane?
Updated 2026-08-14 · Register QBCC
A deck or pergola is one of the most common ways Brisbane homeowners add usable outdoor space, but the quotes come back with a wide spread — and the reason is almost always height, material and whether the structure is roofed. Most Brisbane carpenters price a finished deck by the square metre: hardwood decking supplied and built typically runs A$350–700/m² across Greater Brisbane, with elevated hardwood decks on high-set Queenslanders sitting at the top of that band and simple ground-level treated-pine decks costing noticeably less. A timber pergola or patio frame, supplied and built, is usually quoted as a whole job — from around A$3,500 for a modest attached pergola up to A$12,000 for a larger, roofed structure that needs council approval. Before you compare numbers, three checks sit behind the job rather than two: in Queensland building work valued over A$3,300 must be carried out by a QBCC-licensed contractor; a property inside a City Plan overlay or neighbourhood plan area may need planning approval from Brisbane City Council; and larger, higher or roofed structures need building approval, arranged through a licensed building certifier.
Costs at a glance
Ranges reflect quotes observed locally — not national averages, not advertised "from" prices.
| Service | Typical range (A$) |
|---|---|
Hardwood decking, supply + build (per m²) Based on Canstar's deck cost guide (Apr 2025), citing hipages figures of ~$320/m² for hardwood timber decking, $200/m² for treated pine and ~$1,000/m² for elevated cyclone-rated decking — national figures, not Brisbane-specific. The flat hardwood figure sits just under this range's floor and the elevated figure above its ceiling; the range here covers the built-up middle. Elevated hardwood decks (common on high-set Queenslanders) sit at the top; ground-level treated-pine decks start nearer $250/m². Height, span and balustrading drive the spread. | A$350 — A$700 |
Timber pergola / patio frame, supply + build Based on Shade Kits' national 2026 pergola guide ($2,000–$6,000 for a basic timber pergola, $5,000–$15,000 once roofed, $100–$500/m²) — national figures, not Brisbane-specific — plus Brisbane operator Smart Patios' published approval costings ($800–$1,500 in certifier fees for a basic 15m² patio, with a council application around $850 plus $190 for the final check). A modest attached pergola sits at the low end; larger spans, a roofed structure and council approval push toward the top. | A$3,500 — A$12,000 |
Carpenter hourly rate (standard hours) In line with ServiceSeeking's national quoting data (average $85.42/hr, from $35/hr at the low end; 62% of carpenter quotes are billed hourly) — a national figure, not a Brisbane-specific one. Covers small repairs and non-licensable jobs charged by the hour; callout minimums usually apply, and specialist or heritage work sits higher. | A$65 — A$110 |
What drives the price of a Brisbane deck
The single biggest cost driver on a Brisbane deck is how far it sits off the ground. Many local homes are high-set 'Queenslanders' — timber houses lifted a full storey on stumps — and a deck off the back of one needs deeper footings, taller posts, bracing and compliant balustrading, all of which is why elevated hardwood decks land at the top of the A$350–700/m² supply-and-build range. Material is the next lever: durable hardwoods like spotted gum or blackbutt cost more than treated pine, so a simple ground-level treated-pine deck sits well below that hardwood band. Span, the number of stairs, and whether you want a wraparound all add labour. Because these variables compound, always get the deck priced per square metre as a supplied-and-built figure rather than comparing a bare timber cost against a full quote.
Pergolas, patios and what pushes them to the top of the range
A timber pergola or patio frame, supplied and built, is quoted as a whole job across Greater Brisbane, and the A$3,500–12,000 range is genuinely wide. At the low end is a modest pergola attached to the house — a few posts, beams and rafters left open to the sky. The figure climbs with span (a larger structure needs bigger sections and more footings), with a solid or Colorbond roof rather than open battens, and with anything that triggers council approval. A roofed patio, in particular, is treated differently from an open pergola for approval purposes, so a design that looks only slightly bigger on paper can cost meaningfully more once footings, roofing and approvals are added. As with decks, ask for the frame priced as supplied-and-built so you are comparing like with like.
Licensing, planning approval, building approval: three checks, not two
Three separate systems sit behind any deck or pergola in Brisbane, and it is the middle one people miss.
The first is licensing. If you pay someone to do the work, in Queensland any building work valued over A$3,300 must be carried out by a QBCC-licensed contractor. Doing it yourself works differently: an owner carrying out building work personally on their own land, valued at no more than A$11,000, needs neither a licence nor a permit (QBCC Regulation 2018 sch 1 s 33(1)), while work over A$11,000 must go to a licensed contractor or be done by you under an owner-builder permit (QBCC Act 1991 s 43E) — the permit is what lets an owner self-perform above that threshold, not a ceiling on it.
The second is planning approval, and it is the one that catches this guide's core reader. Brisbane City Council says you may need it if your property sits in a relevant overlay — the Traditional building character overlay is the one that covers pre-war Queenslanders — or in a neighbourhood plan area whose specific requirements the work does not meet, and if it is required you lodge a development application. It is separate from building approval and the size limits below do not waive it.
The third is building approval. Council exempts a low, small, open deck: no building approval where the deck's plan area is no more than 10 square metres, it is no more than 1 metre above natural ground level, it is not roofed, no side is longer than 5 metres, it will not affect the structural integrity of existing buildings, retaining walls or other structures, and it will not alter an existing pool enclosure or fence. Miss any of those and you need building approval, arranged through a licensed building certifier. A pergola is a different structure with different numbers — see the FAQ below.
One thing a licence does not buy you is home warranty cover. That attaches to the work, not to the tradesperson: under QBCC Act 1991 s 67WC(1)(c), building work for something attached or connected to a residence is primary insurable work only if it requires building development approval under the Building Act 1975, is carried out by a licensed contractor, and has an insurable value above the regulated amount of A$3,300 — and s 67WC(2)(b) excludes landscaping. So an approval-exempt low open deck built by a licensed carpenter for A$6,000 carries no cover, and a freestanding open pergola is not a "related roofed building" at all, because s 67WF(1)(a) requires a roof impervious to water or wind. On a job that does clear all three conditions, ask for the insurance notice.
Small jobs, repairs and comparing quotes
Not every job is a full deck. Replacing a few rotten boards, re-fixing a handrail or other small repairs are usually charged by the hour: standard-hours carpentry in Greater Brisbane typically runs A$65–110 an hour, and most carpenters apply a minimum callout, so a ten-minute fix still carries at least an hour or a set fee. For a whole deck or pergola, prefer a fixed, supplied-and-built quote over an hourly estimate — it puts the risk of a bad weather run or a tricky footing on the builder, not you. Whatever the job, get it in writing, confirm the figure is inclusive of GST, and check the QBCC licence before you accept.
Common questions
Does a small deck or pergola need council approval in Brisbane?
It depends which structure and which approval. For building approval, Brisbane City Council exempts a deck whose plan area is 10 square metres or less, that sits no more than 1 metre above natural ground level, is not roofed, has no side longer than 5 metres, does not affect the structural integrity of existing buildings or retaining walls, and does not alter a pool enclosure or fence. A pergola is not a deck: as a class 10 structure it is accepted development under Building Regulation 2021 sch 1 s 13(1) read with s 13(2), at up to 10 square metres of plan area, 2.4 metres in height above natural ground surface with a mean height of no more than 2.1 metres, and no side longer than 5 metres — the 1 metre figure is the deck limit in s 13(1)(c), not a pergola limit. Planning approval is a separate question again: it can still be required if your property is in a City Plan overlay or neighbourhood plan area, so check both before you commit to a design.
Do I need a licensed carpenter to build my deck?
In Queensland, any building work valued over A$3,300 must be done by a QBCC-licensed contractor. As an owner you can personally do up to A$11,000 of work on your own land without a licence, and self-perform larger jobs under an owner-builder permit — but most professionally built decks and pergolas are over the A$3,300 line, so the carpenter should hold a current QBCC licence. What a licence does not do on its own is bring home warranty cover into play: that also requires the work to need building development approval and to have an insurable value above A$3,300 (QBCC Act 1991 s 67WC(1)(c)), so an approval-exempt low deck or an open pergola sits outside the scheme however well licensed the carpenter is.
Why does a hardwood deck cost so much more than a ground-level one?
Two reasons: material and height. Hardwoods like spotted gum cost more than treated pine, and decks off a high-set Queenslander need deeper footings, taller posts, bracing and balustrading. Together these push an elevated hardwood deck to the top of the A$350–700 per square metre supply-and-build range, while a low treated-pine deck sits well below it.
How much does it cost just to repair a few deck boards?
Small repairs are usually charged by the hour rather than by the square metre. Standard-hours carpentry in Greater Brisbane typically runs A$65–110 an hour, and a minimum callout usually applies, so even a quick fix carries at least an hour or a set fee. Ask whether the quote includes the replacement timber, which is charged on top of labour.
