Verandahs and pergolas are usually priced per square metre, but roof style, roofing material and how the structure attaches to your home decide the final figure. An open timber pergola and an insulated-roof verandah are very different builds.
The ranges below help you budget and compare. Always get an itemised quote from a builder who has seen where the structure will attach and how the ground sits.
Verandahs & Pergolas: Typical Adelaide Ranges
Flat-roof verandah (Colorbond)
Around $250 to $450 per square metre. A practical, weatherproof cover that suits most homes. Insulated roof panels sit at the upper end and keep the space cooler.
Gabled or pitched patio
Roughly $350 to $600 per square metre. A more open, high-ceiling feel that suits larger entertaining areas, with more structure and therefore more cost.
Open timber pergola
About $200 to $400 per square metre. The most affordable option for shade and structure, often paired with a deck. Adding a roof later moves it toward verandah pricing.

What Moves the Verandah Number
Roofing material. Polycarbonate is the cheapest cover, Colorbond sits mid range, and insulated sandwich panels cost more but add comfort. This is a major lever on the total.
Footings and ground. Reactive clay, slope or paving to cut through all add to footing cost. Larger spans need bigger posts and footings.
Attaching to the house. How the structure fixes to the existing roof or wall affects flashing, waterproofing and labour. Freestanding structures avoid some of this but need more posts.
Size and span. Wider spans without posts need heavier beams. Lighting, fans and blinds also add to the finished cost.
Council approval. Small pergolas may be exempt, but most verandahs and larger structures need development approval. Check before you commit.

Common Questions
In Adelaide in 2026, a flat-roof Colorbond verandah typically runs $250 to $450 per square metre, a gabled or pitched patio around $350 to $600, and an open timber pergola roughly $200 to $400. A typical 30 square metre verandah therefore lands somewhere between $9,000 and $18,000. Footings, attaching to the existing house, roofing choice (polycarbonate vs insulated panel) and council approval for larger structures move the number.
