How much does a pergola cost in Australia? (2026 guide)

A pergola turns a bare patch of yard into an outdoor room. "How much does a pergola cost?" depends mostly on the material, the roof, and the size. The honest version is a range: roughly $250 to $1,200+ per square metre installed, from a simple open timber frame at the bottom to a powered louvred roof system at the top.

This guide breaks down where in that range your pergola is likely to land, what moves the number, and a worked example so you can sanity-check any quote. Figures are 2026 estimates for Australian residential work and include materials and professional installation, GST inclusive.

Pergola cost per m² by type

| Pergola type | Installed cost (per m²) | Best for | | --- | --- | --- | | Open timber (posts + rafters/battens) | $250-$450 | Partial shade, classic look, budget | | Aluminium + Colorbond or polycarbonate roof | $350-$600 | Low maintenance, full rain cover | | Opening louvred roof system | $600-$1,200+ | Adjustable sun and rain control |

These bands reflect current Australian cost guides, which broadly put pergolas in the $250-$700/m² range for standard work, with opening louvred roofs running well above that.

What actually drives the price

The material is only part of the story. Four things move your quote:

• The roof. An open batten roof is cheapest but gives only partial shade. A solid Colorbond or polycarbonate roof gives full rain cover for more money. An opening louvred roof is the premium choice and costs several times more because of the mechanism.
• Size and span. A bigger footprint means more posts, beams and roofing. A wide span with no middle posts needs heavier beams, which adds cost per m².
• Attached vs freestanding, and footings. Attaching to the house adds flashing and fixing; freestanding needs its own posts and footings. Harder ground means deeper footings either way.
• Finish and extras. Decking or paving underneath, integrated lighting, fans, blinds or screens all add to the bill. If you are pairing the pergola with a new deck, our decking cost guide covers per-m² deck rates.

A worked example

Say you want an aluminium pergola, 4 m x 5 m (20 m²), attached to the house with an insulated Colorbond roof, on an existing paved area.

| Line item | Estimate | | --- | --- | | Aluminium frame, posts and beams | $4,200 | | Insulated Colorbond roofing and flashing | $2,400 | | Footings, fixings and house tie-in | $1,300 | | Labour (2-person crew) | $2,100 | | Total (inc GST) | ≈ $10,000 |

That works out to about $500/m², mid-band for an aluminium roofed pergola. Drop to an open timber frame and you would save roughly $2,500-$3,500; step up to an opening louvred roof and you could add $5,000-$10,000 for the same footprint.

How prices vary across Australia

Pergola labour follows the usual pattern: dearer in Sydney and Melbourne, a little cheaper in Brisbane, Perth and Adelaide, and variable in regional areas depending on travel. Cyclonic zones up north need higher wind ratings, which means heavier members and deeper footings, so the same pergola costs more there. Coastal builds also favour aluminium or treated, durable timber, since exposed structures take a beating from salt and UV.

How to keep the cost sensible

• Match the roof to how you will use it. If you only want dappled shade, an open batten roof is far cheaper than a solid or louvred one.
• Keep the span sensible. A middle post can save a lot on beam sizing if the layout allows it.
• Sort approval and the surface together. Knowing whether you need council approval, and whether the slab or deck underneath is included, avoids the two most common surprises.

Questions worth asking before you commit

• Is council approval included, and who lodges it? Clarify whether the builder handles it or you do.
• Is the structure engineered for my wind zone? Coastal and cyclonic sites need higher ratings.
• Is the surface underneath (deck or paving) included? It is often a separate cost.
• Is the quote fixed price or an estimate? A fixed price protects you from footing surprises.
• What is the warranty on workmanship and the roofing? Louvred systems and Colorbond carry material warranties; the install is separate.

A pergola is a long-term outdoor structure. The cheapest quote that under-sizes the beams or skips the wind rating is rarely the cheapest pergola once the first big storm rolls through.
