Decks are priced per square metre, installed: treated pine $200-$350/m², merbau and hardwood $300-$650/m², composite $350-$700/m². Pergolas are priced by roof type - and the roof is the whole game. Price both below.
Material first, then height, stairs and balustrade - the things that actually move the number. Turn the pergola module on below if you want both priced together.

Frame material barely moves the price - the roof does. Note insulated panels need a steel frame to span their width.
Guide range only - council approval, where needed, is extra and varies by council. Send your details below and we will confirm the job properly.

The numbers behind the calculator - published Australian installed rates, cross-checked.
Pine $200-$350 · Hardwood $300-$500 · Composite $350-$600
Full deck projects typically run $3,000-$11,500, most $5,000-$10,000 (Yellow Pages). Height, stairs, balustrade and removal sit on top of the per-m² rate - which is why this calculator adds them as separate lines rather than hiding them.

Roof type is the price: simple flat and shade roofs at the bottom, gable and insulated panels in the middle, opening louvre roofs at $1,200-$1,800/m² plus automation.
Often exempt - check first
Small decks and pergolas are commonly exempt development (NSW: pergolas and decks up to 25 m², floor up to 1 m, height up to 3 m). Bushfire, heritage and strata rules can override - and approval fees vary too much to quote honestly.
On a 24 m² deck, pine at $200-$300/m² versus premium composite at $500-$700/m² is a $7,000-$10,000 swing before anything else changes.
Raised decks need more structure, stairs - and over 1 m, a mandatory balustrade, which alone runs $150-$700 per linear metre depending on material.
Insulated panels ($900-$1,400/m², single-source - flagged in the calculator) and louvre roofs cost several times a simple flat roof. Published flat-roof rates conflict; we show both rather than averaging.
The decks and pergolas guide covers every material rate, the extras, the exempt-development rules by state and the conflicts between published sources.
