Perth patio builders quote by the square metre, supplied and installed, and the choice of roof moves the price more than anything else. Colorbond on a flat or skillion frame is $250–$600, a gable or pitched Colorbond roof $450–$950, an insulated-panel roof $350–$750 and a polycarbonate roof $220–$540. Turned into whole jobs, a small skillion patio comes to $6,500–$13,000, while a medium gable or insulated patio runs $14,000–$30,000. In a city with a long, hot, nearly rainless summer, how cool the space stays underneath matters as much as the price. All prices include GST.

Perth’s Patio Market in 2026
In WA a roofed outdoor area is a Class 10a building, and the permit-free pergola rule covers only open, unroofed structures. Since 1 July 2026, patio work under $50,000 no longer needs a registered building contractor, but the permit rules still apply.
At the City of Perth a certified application has a legislated ten business days and an uncertified one 25. In the Perth table a flat Colorbond roof is $250–$600 a square metre and a gable $450–$950.
How Patio Costs Vary Across Perth
Western Suburbs
Typical cost: $350–$810/sqm installed
Cottesloe, Claremont, Nedlands, Subiaco, Dalkeith. Perth's most expensive area. Premium finishes and coastal exposure near the river and beaches; insulated roofs and louvres are common.
Northern Coastal
Typical cost: $330–$800/sqm installed
Scarborough, Hillarys, Joondalup, Sorrento. Strong sea breezes mean higher wind ratings and stainless fixings. Poolside and beach-house patios dominate.
Southern Suburbs
Typical cost: $290–$720/sqm installed
Fremantle, Rockingham, Baldivis, Cockburn. A mix of heritage Fremantle cottages and newer southern estates. Access and block type drive the price.
Eastern Suburbs
Typical cost: $250–$640/sqm installed
Midland, Guildford, Forrestfield, High Wycombe. More affordable, with flatter blocks and easy access. Skillion Colorbond is the budget staple.
Hills & Outer
Typical cost: $250–$640/sqm installed
Kalamunda, Mundaring, Ellenbrook, Byford. Bushfire-prone hills areas need BAL-rated materials; larger blocks suit bigger gable and flyover patios.

Cheap patios in Perth: the lowest installed price is a polycarbonate or flat skillion Colorbond roof on an existing slab, $220/m² at the bottom of the band or $5,500 for a small 15 m² patio. Quotes below that are usually kit-only or exclude the permit and footings. An insulated roof ($350–$750/m²) costs more but turns a west-facing Perth patio from an oven into a room.
What moves a patio quote in Perth:
- Roof type: skillion is the base; gable, flyover and insulated panels each add structure or material.
- Size and span: wider spans need bigger beams and more posts; a long patio along the house costs less per metre than a deep one.
- Attachment: a freestanding patio needs its own posts and footings; attached patios need the house fascia or wall checked for the load.
- Base: an existing slab or paving is the saving; a new slab or footings into sand or clay is a separate line.
- Approval: most patios over a certain size need a building permit, which the installer usually handles and prices.
For patio quotes in Perth that compare, give the square metres, the roof type, whether there is a slab, and whether the permit is included.
What Affects Patio Costs in Perth
Summer heat under the roof
Perth Metro averages 31.7 °C in February and 31.4 °C in January, and December brings only 9.6 mm of rain (BOM averages). A plain steel sheet heats up in that sun and radiates warmth onto the table below, and that is the case for insulated panels at $350–$750 on a patio used all summer. An existing patio can be upgraded later at $200–$400.
Gable, flat or flyover
A gable patio is typically $700 a square metre against $400 for a flat roof, because the pitched frame takes more steel and labour. The extra height lets hot air rise away from the seating. A flyover roof at $300–$650 lifts above the existing gutter line instead of tucking under it.
Room for a large alfresco
Perth is a city of big detached homes: 77.8% of dwellings are separate houses and 45.7% have four or more bedrooms, against 34.8% nationally (ABS 2021 Census). If you want an outdoor room scaled to a family home of that size, a large insulated flyover patio costs $18,000–$38,000. Mark out the area with string before quoting, since every square metre is priced.
Building permit timing
Schedule 4 of the WA Building Regulations lists the building work that needs no permit, and your builder or council can tell you whether your patio falls inside it. In the City of Perth, a certified application, which carries a certificate of design compliance signed by a registered building surveyor, has a legislated processing time of ten business days; an uncertified application for a house or incidental structure takes twenty-five business days.
Builder registration
In most areas of Western Australia, builders doing building work worth $20,000 or more must be registered with Building and Energy. A medium patio sits around $20,000 and a large one well above it, so many quotes cross that line. Ask for the registration number on the quote and check it before you pay a deposit.
Slab, footings and winter rain
Posts can often stand on top of an existing slab or paved area; a new concrete base adds $80–$160 per square metre. Footing holes and pours are easier to schedule outside Perth's wet season, when July averages 147.0 mm and June and August both pass 125 mm (BOM averages). Exposed or sloping sites may need engineered footings, so ask what the quote assumes.
Fans, lights and blinds
Lighting with a ceiling fan adds $600–$2,500, and track-guided zip blinds that block the late-afternoon sun cost $200–$450 per square metre. Both are simplest to fit during the build, when cable can run inside the frame and blind brackets can be planned into the beam.
