Triple Carport: Costs, Sizes, Council Approval and Design Options for Australian Homes (2025)

What is a triple carport and who is it for?

A triple carport is a three-bay, open-sided roofed structure designed to protect multiple vehicles—utes, SUVs, caravans, and boats—from sun, rain and hail. For Australian homeowners, renovators and property investors, a premium Colorbond steel carport adds practical cover, boosts street appeal, and can be engineered to local wind, fire and corrosion conditions.

Common use-cases include boat and caravan cover, farm machinery storage, and adding a drive-through canopy to a custom-built double garage in Perth or a rural property in NSW.
