Carport Cost Guide, Australia 2026

Price ranges based on current Australian installation rates. Actual costs depend on size, roofing material, whether a slab is included, and your state.

Cost by carport type

Single freestanding (1 car)$4,000–$8,000

Standard Colorbond roof, 2 or 3 posts, no enclosed sides. Concrete footings included.

Double freestanding (2 cars)$6,500–$14,000

Wider span requires more posts and a stronger frame. Most popular residential choice.

Single attached (lean-to)$5,000–$10,000

Fixed to an existing wall of the house. Usually requires a building permit.

Double attached (lean-to)$8,500–$18,000

Larger lean-to carport. Structural connection to the house adds complexity and cost.

Prices include supply and installation. Polycarbonate roofing adds 15 to 20% over Colorbond. Side enclosures add $800 to $2,000 per panel.

What affects the price

  • ·Freestanding vs attached: Attached carports cost slightly more due to the structural tie-in with the existing building and the permit requirements that almost always apply.
  • ·Roofing material: Colorbond steel is the standard choice. Polycarbonate panels let in natural light but add 15 to 20% to the roof cost. Insulated panels are available for hotter climates.
  • ·Concrete base: If there is no existing driveway or hardstand, new concrete footings or a full slab are needed. Expect $85 to $120 per square metre for a plain finish slab.
  • ·Enclosed sides: Open carports are the base price. Adding side panels for privacy or wind protection adds $800 to $2,000 per enclosed side.
  • ·Council permits: Attached carports almost always require a building permit in Australia. Freestanding carports over a certain size (typically 20m² or more) may also need one. Budget $500 to $1,500 for the approval process.
