Factors Influencing the Cost of a Double Carport


Multiple characteristics determine the total cost of double carports, including the selection of building materials, along with site location and design features, as well as landscape conditions present at the installation spot. Key factors that affect the overall cost of a double carport include the following:



Material Type



The selected construction materials determine both initial construction expenses and whole life expectancy maintenance costs. Each material offers distinct advantages:



  • Steel: One of the most cost-effective and low-maintenance options. Steel maintains a long lifespan as it appears in both DIY kits and prefab solutions, as well as enduring all weather conditions. The total expense ranges from $4,500 to $10,000 based on constructing it yourself or obtaining professional installation.


  • Timber: Building exterior from natural materials produces upscale aesthetics suited for traditional houses. Long-term maintenance includes both sealing and repainting procedures for this material. The estimated cost is $7,000 – $14,000.


  • Aluminium: Aluminium provides low maintenance standing with minimal requirement for upkeep alongside superior resistance to rust. It also remains lightweight in its composition. The higher cost of aluminium compared to steel makes it suitable for environments with high moisture content that threaten steel surfaces. The estimated cost is $6,000 – $12,000.


Roofing Material



A roof system influences a building's looks and storm protection and plays an essential role in determining total expenses.

  • Attached Carports: This is an affordable option. The use of existing structure walls as supports decreases the cost of materials as well as labour expenses. The way a structure attaches to home buildings creates better integration between the carport and house.


Ground Preparation and Site Access

  • Sydney & Melbourne: Higher installation prices occur because urban areas have increased costs along with high trade rates and delivery expenses.


  • Regional NSW, VIC, QLD: Lower labour rates along with competitive market prices tend to reduce the cost of these structures. The delivery costs for materials will increase in some remote areas.


Customisation & Add-ons



The introduction of functional components together with comfort elements leads to higher costs since they are added to your carport building.



  • Lighting or Power Outlets: The installation of lighting and electric charging capabilities makes the carport ideal for evening purposes and powering electric vehicles. The estimated cost is $200 – $1,000.
