How to Quote a Pergola Build in Australia
A pergola can be a weekend of open timber or a full outdoor room with a solid roof and lighting. Here's how to quote a pergola so the roofing choice, footings and council rules all land in the price.
A pergola is one of the most variable jobs a carpenter quotes. The same footprint can be open treated pine or a steel frame under an insulated roof with fans and downlights — and the price swings accordingly. The quotes that come unstuck are the ones that priced the frame and glossed over the roofing, the footings and the council rules. Here's how to quote a pergola properly.
What a good pergola quote covers
Break the build into every part before you price it. A complete pergola quote covers all of these:
- Footings — concrete pads and post brackets or stirrups, priced per post.
- Posts — timber or steel, with the species and size spelled out.
- Beams and rafters — size and spacing, referenced to a span table.
- Roofing — open, polycarbonate, Colorbond, shade cloth or insulated panel; the single biggest price driver.
- Fascia, trims and guttering — guttering and downpipes are only needed once the roof is solid.
- Hardware — bolts, brackets and stirrups, quoted properly rather than rounded off.
- Electrical — lighting, fans and power points, as their own add-on line.
Quote the roofing as its own section so the customer can compare options — open timber, Colorbond and an insulated panel are wildly different prices, and letting them choose keeps the conversation on value instead of one scary number.
Pergola costs in 2026
Most pergolas are priced per square metre, supplied and installed, and the roofing choice moves the rate more than anything. Current starting points:
| Build type | Cost / m² | Best for |
|---|---|---|
| Treated pine, open roof | $250–$400 | Budget builds and a shaded, airy feel |
| Hardwood with Colorbond roof | $400–$700 | A weatherproof outdoor room |
| Steel frame with Colorbond | $500–$900 | Long spans and low maintenance |
| Insulated panel roofing (roof only) | $150–$250 | Premium, keeps the heat out |
A standard 4x3m pergola typically lands around $5,000–$15,000 all up, depending on the frame and roof. Insulated panels like SolarSpan are the premium add-on, quoted per m² on top of the frame.
Footings and structural requirements
The footings and framing are what stop a pergola moving in the wind, so size them to the job rather than a default. Check local requirements before you commit to dimensions.
- Standard posts sit on 400x400mm footings, at least 450mm deep — deeper on reactive or sandy soils.
- Posts are typically 100x100mm or 125x125mm hardwood, or 90x90mm steel.
- Beam sizes follow the span — use a span table, and get engineering for anything over 3m.
- A pergola attached to the house may need an engineer's certificate for the connection.
Council approvals
Pergola approval rules vary a lot by state and council, so check before you quote rather than after.
- As a rough guide, pergolas under 20m² and under 2.7m high that aren't in a front setback are exempt in most states.
- Those thresholds shift by council and by zone — confirm the local rules for the actual address.
- Where approval applies, add the council application fee and any engineering certification as their own lines.
- Front-yard and boundary jobs are the most likely to need approval — flag them early.
Common mistakes that eat your margin
- Quoting one roof and building another. Roofing is the biggest price driver. Lock in whether it's open, polycarbonate, Colorbond or insulated panel before you send a number.
- Assuming freestanding. An attached pergola has different structural requirements and may need an engineer's certificate. Confirm freestanding vs attached on site.
- Under-sizing the footings. Skimping on footing size or depth is how a pergola ends up moving. Size them for the soil and the wind, not the easy dig.
- Forgetting the guttering. A solid roof needs gutters and downpipes. Leave them off a Colorbond quote and you're buying them yourself.
- Skipping council checks. Assuming a job is exempt when it isn't leads to a stop-work and a retro application. Check the council rules before you quote.
Pro tips for a pergola quote that holds
- Measure the area and check the ground levels on site — pergolas often go on uneven ground.
- Confirm freestanding or attached before you price the structure.
- Quote two or three roofing options so the customer can compare.
- Offer lighting and fans as a clearly priced add-on, not a surprise.
- Specify timber species and member sizes in writing to head off scope creep.
- Add guttering and downpipes whenever the roof is solid.

Frequently asked questions
How much does a pergola cost in Australia?
A standard 4x3m pergola runs roughly $5,000–$15,000 supplied and installed. Open treated pine is the cheapest at $250–$400/m²; a steel frame under Colorbond can reach $500–$900/m².
Do I need council approval for a pergola?
Often not — many states exempt pergolas under 20m² and under 2.7m high that aren't in a front setback. But the rules vary by council and zone, so always check the local requirements before you quote.
Should I quote pergola roofing separately?
Yes. Roofing is the biggest single price driver, so give it its own section with two or three options. It lets the customer compare open, Colorbond and insulated panel on value rather than reacting to one total.
