Added 2024 WA wind-rating compliance notes • Added council-approved sheds WA • Added cyclone-rated sheds QLD
- Colorbond: Pre-painted, corrosion-resistant steel by BlueScope suited to Australian conditions.
- Zincalume: Aluminium/zinc coated steel with high corrosion resistance; usually unpainted.
- Wind regions (A–D): As per AS/NZS 1170.2; C and D are cyclonic (e.g., coastal QLD/WA).
- N and C ratings: Wind classifications for non-cyclonic (N1–N6) and cyclonic (C1–C4) design.
- BAL: Bushfire Attack Level as per AS 3959 (BAL-12.5 to BAL-FZ) guiding material/spec choices.
- Terrain Category: Surrounding exposure (e.g., TC2 suburban, TC3 open) impacting wind loads.
- Corrosion categories: C1–C5 environment aggressiveness (C4–C5 = severe/coastal).
What are the best shed materials for Perth’s climate?
Perth summers are hot and dry; coastal suburbs face salt-laden winds. For a custom Colorbond double garage in Perth, consider:
- Cladding: Colorbond Ultra or MagnaFlow coatings near the coast (C4/C5 environments); Zincalume for inland value builds.
- Insulation: R1.8–R2.5 roof blanket plus anticon to reduce heat and condensation.
- Roofing: High solar-reflectance Colorbond colours (Surfmist, Shale Grey) for lower heat gain.
- Ventilation: Ridge vents + eaves vents; consider whirlybirds for unpowered extraction.
Colorbond vs Zincalume — which is better for WA, QLD and coastal NSW?
| Feature | Colorbond | Zincalume |
|---|---|---|
| Finish | Pre-painted, many colours | Metallic (unpainted) |
| Coastal performance | Use Colorbond Ultra near severe marine (C4/C5) | Good corrosion resistance; may still need paint/coating near coast |
| Thermal | Cooler light colours reduce heat load | Reflective surface can be bright; heat gain still high without insulation |
| Aesthetics/HOA | Often preferred for residential streetscapes | Great for rural/industrial looks |
| Cost | Higher upfront | Lower upfront |
| Best use | Homes, carports, premium garages | Farm sheds, internal walls, budget builds |
Always check manufacturer guidance and local corrosivity maps. See Australian Steel Institute and CSIRO resources for durability insights.
Flat roof vs gable roof for Australian garages
| Aspect | Flat/Skillion | Gable |
|---|---|---|
| Looks | Modern, low-profile suits urban infill | Classic profile suits most homes |
| Water run-off | One-way fall; bigger gutters needed | Two-way; simpler drainage |
| Ceiling height | Higher at one side; good for hoists | Central clearance; good for storage |
| Wind performance | Low drag profile in exposed areas | Excellent with correct bracing |
| Solar panels | Optimize pitch and orientation | May require tilt frames |
DIY shed kits vs custom-built garages
| Factor | DIY Shed Kits | Custom-Built |
|---|---|---|
| Cost | Lowest upfront | Higher; tailored inclusions |
| Time to install | Weekend warrior to 2–4 days | Pro crew 1–3 days (size dependent) |
| Council approval | You manage drawings and permits | Supplier handles approvals |
| Site challenges | Less forgiving for slopes/soil issues | Engineered to suit site loads |
| Warranty | Parts/materials | Materials + workmanship |
| Best for | Small garages, garden sheds, rural DIY | Premium builds, tight sites, BAL or cyclonic |
How much does a steel garage cost in Australia in 2025?
Indicative ranges (materials + install; site-dependent):
- Single Colorbond steel garage (3 x 6 m): $6,500–$12,000
- Double garage (6 x 6 m): $10,500–$22,000
- Triple garage or garage + workshop (7 x 9 m+): $18,000–$40,000
- Custom carports (single/double): $3,500–$12,000
- DIY shed kits (ex. slab): from $2,500 for compact sizes
Excludes slab, electrical, excavation, and council fees. Industry outlooks for 2024–2025 note steel price stabilisation but strong labour demand. See HIA and Master Builders updates for market context.
Which garage type is best? Use-cases and specs
For growing families, a Double Garage in Australia offers the flexibility and space to park multiple vehicles while also providing secure storage for other household items.
- Urban single/double garages: Colorbond cladding, automated roller door, insulation, termite-proof slab edge.
- Rural sheds NSW and VIC: Wider bays for farm machinery storage, heavy-duty purlins, extra bracing.
- Industrial workshops Brisbane: Extra height, wind bracing, mezzanine options, PA doors and glazing.
- Boat & caravan storage: 3.0–3.6 m eave height, cyclone tie-downs in northern QLD and WA coasts.
- Custom carports Melbourne: Powder-coated posts, skillion roofs to boundary, integrated gutters.
Compliance basics: wind ratings, bushfire, and approvals
Wind loads and cyclonic design
Design to AS/NZS 1170.2 with N1–N6 (non-cyclonic) or C1–C4 (cyclonic). Northern QLD and WA coasts can be Region C/D. Specify wind-rated sheds for cyclonic areas including hold-downs, screw patterns, and door wind-locks.
BAL (bushfire) requirements
In bushfire-prone areas, follow AS 3959. Choose ember-resistant mesh, sealed gaps, metal gutters, and non-combustible cladding. Check local mapping before ordering.
Slab and structure
Slab design per AS 2870 with site soil test (Class A–E). Steel design to AS 4100/4600; roofing to AS 1562.1. Electrical works by licensed sparkies to AS/NZS 3000.
Energy and comfort
Insulation, radiant barriers, and light-colour roofs reduce summer heat load. See Energy.gov.au for guidance.
How to get council approval for your custom shed in WA
Actionable steps to a council-approved shed
- Check zoning and R-Codes: Street setbacks, open space, and height limits.
- Order site plan + engineering: Supplier provides certified drawings for your wind region and terrain category. Added 2024 WA wind-rating compliance notes
- Lodge BA2/BA3 forms: Confirm whether planning approval is required or if it’s exempt (size varies by council).
- Footing/slab inspection: Arrange pre-pour inspection if required.
- Final sign-off: Keep manuals, warranties, and engineering certificates for resale and insurance.
For QLD, use the relevant state planning portal and cyclone region maps. Check Bureau of Meteorology cyclone guidance: BOM cyclone information.
Timber garage kits Australia: when wood beats steel
Steel dominates for durability and approvals, but timber garage kits appeal for heritage aesthetics and DIY. Choose H3/H4 treated framing, metal roof cladding, and BAL-compliant details where needed. Ideal for regional VIC/NSW cottages or acreage where you want a softer look.

Where to find “garage construction near me”
Shortlist local shed builders with:
- In-house engineering to AS/NZS standards and NCC 2022 compliance
- Experience with council-approved sheds WA/QLD/NSW
- Site measure and fixed-scope quotes (avoid vague PC sums)
- Material warranties (BlueScope) and workmanship warranty in writing
Check credentials via HIA and Master Builders Australia.
Maintenance for the best garage performance
- Rinse coastal garages quarterly to remove salt; clear gutters and downpipes.
- Touch up scratches with approved paint systems.
- Check door springs, wind-locks, and auto-openers annually.
- Re-seal slab control joints and inspect for settlement near stormwater.
FAQs
How long does a steel garage take to build?
From order to handover: 3–8 weeks depending on approvals and supply. On-site install for a double garage is commonly 1–3 days.
Can I add solar to my garage?
Yes. Ensure purlin spacing and roof profile suit your racking. Skillion roofs can optimise pitch without tilt frames.
Is Zincalume okay near the beach?
For severe marine environments, Colorbond Ultra or additional protective systems are preferred. Always check distance-to-coast guidelines.
Do I need a permit for a carport?
Most councils require permits beyond small exempt sizes. Verify with your LGA; span, height, and boundary setbacks apply.
