Single Carport Kit Australia: Sizes, Prices, Wind Ratings, Council Approval (2025 Guide)
Looking for a durable, council-ready single carport kit that won’t sag, rust, or blow away in a summer storm? This expert guide brings together Australian standards, regional wind data, and decades of shed-building know‑how so you can spec, price, and order with confidence—whether you want a simple driveway carport or a feature single garage carport attached to your home.
Primary focus: single carport kit. Also covered: cheap carports kits, small carport options, carport kits prices, carport kits for sale, carport sizes, carport frame choices, and custom design paths for premium Colorbond steel solutions.
Why choose a single carport kit?
- Vehicle protection: Keep sun, hail, and debris off sedans, SUVs, and utes—ideal as a driveway carport solution.
- Compact footprint: A small carport suits townhouses and tight side setbacks while adding value to rental stock and flips.
- Fast install: DIY shed kits with pre-punched, galvanised C-sections reduce on-site time and waste.
- Future-ready: Upgrade later to a single garage carport (wrap-in walls/roller door) if you need enclosed storage.
- Affordability: Lower cost than a brick garage, with premium Colorbond roofing for long-term durability.
Standard carport sizes in Australia (single bay)
Most single carport kits are engineered around common vehicle envelopes and clearances.
- Typical widths: 3.0 m, 3.2 m, 3.5 m, 3.6 m
- Typical lengths: 5.4 m, 6.0 m, 6.6 m (allow extra for tow bars/utes)
- Clear height at eave: 2.1–2.7 m standard; 3.0 m+ for 4WDs with racks or small boats
- Roof styles: Skillion (flat/mono‑pitch), gable, Dutch gable; match your home’s pitch for a seamless look
- Posts: 75×75 or 90×90 SHS, or galvanised C-section with base plates for slab or embedment for piers
Tip: For tight driveways, a 3.2 m width and 6.0 m length is a versatile “single carport” footprint that suits most Australian vehicles.
Single carport kit prices in 2025 (Australia)
Indicative supply-only pricing (ex‑install, inc‑GST) for engineered kits in Colorbond or Zincalume:
- Entry “cheap carports kits” (Region A/B, skillion roof, 3.0×5.4 m): $2,200–$3,100
- Mid-range (3.5×6.0 m, gable roof, guttering, downpipes): $3,300–$4,800
- Premium/cyclonic or coastal (Region C/D, heavier carport frame, Colorbond Ultra): $4,800–$7,500+
Installed turnkey pricing varies by concrete, fixings, and access. Expect $1,800–$4,000 for install in metro areas (more if posts need deep piers or rock excavation).
What’s usually in the box: engineered drawings, galvanised frame, roofing sheets, ridge/cappings, gutters/downpipes, brackets, tek screws, and hold‑down details. Ask for an itemised quote for transparent carport kits prices.
What are the best carport materials for Perth’s climate?
Perth’s hot summers and coastal air demand reflective, corrosion-resistant materials. Here’s the core comparison:
Colorbond vs Zincalume — Which is better for WA conditions?
| Feature | Colorbond | Zincalume |
|---|---|---|
| Coating | Painted over zinc/aluminium alloy | Zinc/aluminium alloy (no paint) |
| Heat reflectivity | High (lighter colours reduce heat gain) | Moderate |
| Coastal durability | Colorbond Ultra recommended within ~200–400 m of surf | Less suitable very close to surf |
| Aesthetics | Large colour range (Monument, Surfmist, etc.) | Industrial metallic look |
| Cost | $$ to $$$ | $ to $$ |
Pro Tip: Did you know using insulated roof panels or an anti‑condensation blanket can reduce under‑roof temperatures by up to 10°C in summer?
Engineering, wind ratings, and compliance
Australian carports must be engineered to AS/NZS 1170.2 (wind actions), with steel design to AS/NZS 4600 or AS 4100, and fixings/footings sized for site conditions.
- Wind Regions: A/B (non‑cyclonic), C/D (cyclonic). Many coastal/remote areas of QLD and WA are Region C or D.
- Wind Classes (housing): N1–N4 (non‑cyclonic) and C1–C4 (cyclonic). Your kit should state compliance.
- Terrain Category: TC2 or TC3 typical suburbs; affects uplift on your carport roof.
- BAL (Bushfire Attack Level): BAL‑12.5 to BAL‑40/Flame Zone may require specific materials/clearances.
Added 2024 WA wind-rating compliance notes — Many Perth metro sites fall under Region B, but coastal and hilltop sites can experience higher speeds. Your engineering should nominate wind region, terrain category, topographic multiplier, and connection design (e.g., M12/M16 hold‑downs, embedment depth and footing diameter).
- Typical footings (guide only; engineer to confirm): 350–450 mm dia x 600–900 mm deep for Region A/B; deeper/wider and heavier hold‑downs for C/D.
- Coatings: Hot‑dip galvanised base plates and fasteners for coastal corrosion categories; Colorbond Ultra within surf influence zones.
How to get council approval for your custom shed in WA
- Site plan & elevations: Show setbacks, easements, stormwater, and heights.
- Engineering: AS/NZS‑compliant drawings and certification (Certificate of Design Compliance in WA).
- Building permit: Lodge with your local government for approval prior to construction.
- Stormwater: Connect gutters/downpipes to approved disposal (soakwell or system).
- Final sign‑off: Arrange inspections as required by the permit conditions.
Timeframe: 10–25 business days for straightforward applications.
Other state notes
- QLD: cyclone-rated sheds QLD often require Region C/D engineering; private certifier issues Form 15/16. Check siting with local planning.
- VIC: Building permit via RBS; some single carports may be exempt with strict size/setback rules—verify before ordering.
- NSW: Some single carports qualify as exempt development if under size/height and behind the building line; otherwise CDC/DA applies.
Design choices that matter (and why)
Roof style: skillion vs gable
| Option | Pros | Considerations |
|---|---|---|
| Skillion (flat/mono) | Cheaper, fewer parts, easy to attach to fascia; modern look | Lower central clearance; ensure fall for drainage |
| Gable | Better airflow, more headroom at centre; suits heritage homes | Slightly more cost and assembly time |
Carport frame and finishes
- Frame: Galvanised C-section purlins/girts or SHS posts with rafter beams engineered to your wind region.
- Fixings: Cyclone-rated screw patterns and brackets in C/D regions; stainless where corrosion risk is high.
- Finishes: Colorbond colours to match gutters/fascia; powder-coated posts for a premium architectural look.
- Water: Gutters/downpipes to approved stormwater; add leaf-guards under heavy tree cover.
- Comfort: Anti‑condensation blankets, roof insulation, and LED motion lighting for usability at night.
- Future-proof: Solar-ready purlin spacing and conduit pathways.
DIY kit vs installed carport
- DIY shed kits: Best if you’re handy with a mate on a weekend; follow torque specs on hold‑downs and screw patterns.
- Installed: Ideal for cyclonic/coastal sites, complex footings, or time-poor owners; ensures compliance and warranty.
Typical DIY time: 1–2 days for an experienced crew on a level site, longer for gable roofs or rock digging.

5‑Step Buying Guide for Custom Sheds and Carports in Australia
- Measure and mark: Confirm clear widths/heights around eaves, meter boxes, and driveway fall.
- Pick your spec: Choose roof style, finish (Colorbond vs Zincalume), and clearance height for your tallest vehicle.
- Engineer for site: State/region (N1–N4 or C1–C4), terrain category, topography, BAL rating, and corrosion category.
- Plan approvals: Check if exempt or if you need a permit/CDC; prepare site plan, elevations, and stormwater detail.
- Order and schedule: Lock in lead times, delivery access, concrete pour, and install dates; keep certifier paperwork ready.
FAQs: single carport kit in Australia
What size is a standard single carport?
Commonly 3.0–3.6 m wide and 5.4–6.6 m long with 2.4–2.7 m eave height. Utes/4WDs often benefit from 3.5 m × 6.0 m at 2.7 m eave.
Do I need council approval?
Often yes. Some states allow exempt development if strict criteria are met (size, height, setbacks, behind building line). When in doubt, plan for a building permit or CDC.
Is Colorbond worth the upgrade?
Yes for most coastal and hot climates. Colorbond offers colour stability, heat reflectivity, and corrosion resistance; use Colorbond Ultra close to breaking surf.
Can I DIY?
Yes, if you’re competent. Follow engineering, footing sizes, and screw patterns. Consider pro install for cyclonic regions, steep sites, or complex stormwater connections.
What about bushfire zones?
In BAL areas, you may need specific materials, ember screening, and clearance to vegetation. Confirm with your certifier.
How quickly can I get a kit?
Typical manufacture lead times are 2–4 weeks; longer during peak periods or for custom powder-coat colours.
