Pergolas in Sydney: open, louvre and roofed pergolas with NSW prices
BeforeFixed Aluminium Slat PergolaPergolas in Sydney cost from about $11,000 to $12,500 for a 6 × 4.5 m open timber pergola to about $32,000 to $37,500 for an adjustable louvre roof. Fixed aluminium slat pergolas, freestanding pavilions and pergolas with a Colorbond roof sit in between.
In Sydney, "pergola" covers a lot. Many people use it for an open timber frame or a louvre roof. They also use it for a solid metal roof that Perth would call a patio. This page covers all three.
What does a pergola cost in Sydney in 2026?
Here are indicative installed prices for the pergola styles in NSW, including GST.
| Style | 3 × 3 m | 5 × 4 m | 6 × 4.5 m |
|---|---|---|---|
| Adjustable Louvre Pergola | $15,500 to $18,000 | $24,000 to $28,000 | $32,000 to $37,500 |
| Open Timber Pergola | $7,500 to $8,500 | $8,000 to $9,500 | $11,000 to $12,500 |
| Fixed Aluminium Slat Pergola | $11,500 to $13,500 | $11,500 to $13,500 | $15,000 to $18,000 |
| Pyramid Roof Pavilion | $15,000 to $17,500 | $17,000 to $20,000 | $23,000 to $27,000 |
Indicative installed prices in New South Wales, including GST, rounded. Pavilion is freestanding, the others attached to the house. Updated 28 October 2026.
For a pergola with a solid roof, a flat Colorbond roof is about $13,500 to $16,000. A gable roof is about $18,500 to $21,500 for the same size. Sydney prices run higher than Perth or Adelaide for the same structure. Tight access to a terrace backyard, sandstone under the footings and approval costs also push a quote up.
Sydney's climate: more rain than sun
Sydney is milder and much wetter than people expect. The Bureau of Meteorology's long record at Observatory Hill, near the harbour, shows:
| Sydney Observatory Hill (BOM) | Figure |
|---|---|
| Mean max temperature, January | 26.0 °C |
| Days of 30 °C or more | 15.2 a year |
| Mean annual rainfall | 1,213.4 mm |
| Days with 1 mm of rain or more | 99.5 a year |
| Wettest months | March (131.6 mm) and June (133.1 mm) |
| Mean daily sunshine | 6.8 hours |
| Mean 3pm humidity, February | 64 % |
Rain is spread across the year, with 7 to 10 rain days every month. Suburbs away from the harbour often run hotter than this coastal station. Either way, a Sydney pergola is used through a lot of wet afternoons.
Which pergola suits a Sydney home?
Adjustable louvre pergola
With about 100 rain days a year, a louvre roof earns its price in Sydney. Open the blades on a clear day, close them when a shower comes through. It is about $32,000 to $37,500 for 6 × 4.5 m.
BeforeAdjustable Louvre PergolaFixed aluminium slat pergola
A slat pergola gives shade without the upkeep of timber, which matters in humid air. NSW exempt rules ask for metal parts to be low reflective and factory pre-coloured, which powder-coated slats usually are.
Open timber pergola
Timber still suits a Federation home or a leafy North Shore garden. WoodSolutions rates H3 treated timber for outside, above-ground use; posts set in the ground need H5 or a Class 1 durable hardwood. In bushfire prone areas, see the approval note below.
Pergola with a Colorbond roof
If you want full rain cover, a roofed pergola is the practical answer in Sydney. We call these patios on our site, so see our Sydney patios page for insulated, flat and gable roofs.
Do you need approval for a pergola in Sydney?
NSW has statewide exempt development rules for balconies, decks, patios, pergolas, terraces and verandahs. If your pergola meets every standard, no council approval is needed.
Approval in New South Wales, in short
In NSW a patio, pergola, deck or verandah can be built with no approval at all if it meets the exempt development rules in the state Codes SEPP: behind the front building line, at least 900 mm from side and rear boundaries in most residential zones, no more than 25 m2, no more than 3 m high, and roofed structures must not rise above the house gutter and must drain into the existing stormwater system. If it does not fit, you can get a fast Complying Development Certificate from the council or a registered certifier, or lodge a development application with the council. Heritage and bushfire land add limits. Many patio installers organise the CDC or DA for you.
Read the New South Wales approval guide. Your installer usually handles the paperwork.
The key exempt standards from the NSW Planning Portal:
- Size: no more than 25 m² per structure.
- Total on the lot: 15 % of the house's ground floor area on lots over 300 m². On lots of 300 m² or less, it is 25 m².
- Height: no more than 3 m above existing ground level.
- Setback: 900 mm from the boundary in most residential zones (5 m in rural zones and R5).
- Position: not forward of the building line of any road frontage.
- Bushfire prone land: non-combustible if it is less than 5 m from the house.
A 6 × 4.5 m pergola is 27 m², just over the limit. A 5 × 4 m pergola is 20 m² and can fit. Our NSW council approval guide covers the other pathways.
Sydney details worth knowing
- Terraces: on lots of 300 m² or less, the 25 m² cap counts every deck and pergola together. An existing deck can use up most of it.
- Heritage conservation areas: many older inner suburbs sit in one. There, an exempt pergola must be behind the building line of any road frontage.
- BASIX shading: if a pergola shades a new window, fixed battens must run parallel to it. Roof sheeting needs a shading coefficient below 0.35, says the Planning Portal.
- Bushfire suburbs: near the bush edge, the non-combustible rule within 5 m usually means aluminium or steel instead of timber.

Common questions
How much does a pergola cost in Sydney?
A 6 × 4.5 m open timber pergola in Sydney is about $11,000 to $12,500. Aluminium slats are about $15,000 to $18,000, and a louvre roof about $32,000 to $37,500. A pergola with a solid Colorbond roof is about $13,500 to $16,000. All are indicative installed ranges.
Do I need council approval for a pergola in Sydney?
Not always. Under the NSW exempt development rules, a pergola needs no approval if it meets every standard. These include no more than 25 m², no more than 3 m high, behind the building line, and set back from boundaries.
Can I build a timber pergola on bushfire prone land in Sydney?
Under the NSW exempt rules, a pergola on bushfire prone land that is less than 5 m from the house must be non-combustible. That rules out timber for the exempt pathway, so aluminium or steel is the usual choice.
What size pergola can I build without approval in Sydney?
The NSW exempt limit is 25 m² per structure. On a lot of 300 m² or less, the total for all such structures is also 25 m². On many inner Sydney terraces, 5 × 4 m is a safer size than 6 × 4.5 m.
Does a roofed pergola count for BASIX?
It can. The NSW Planning Portal says polycarbonate or similar sheeting must have a shading coefficient below 0.35 to count as shading. Clear sheeting generally does not meet it, so a tinted sheet is needed.
