Sheds Cheapest in Australia: Smart Ways to Save on Colorbond Steel Sheds (Without Cutting Corners)
If you’re searching “sheds cheapest,” you’re not alone. But the lowest sticker price often leads to higher lifetime costs. This guide distils what Australia’s top shed builders include (and exclude), how to compare prices on storage buildings like-for-like, and where you can genuinely save money—whether you want a compact affordable garden shed, a custom-built double garage in Perth, or a cyclone-rated machinery shed in North Queensland.
We cover: steel grade, Colorbond vs Zincalume, wind ratings (Region A–D), council approvals, DIY shed kits versus installed, and practical case studies from WA, QLD, VIC and NSW. Expect industry jargon made simple, aligned to Australian Standards and climate realities.
Why “sheds cheapest” can cost more long-term
- Under-spec steel thickness or no engineering can fail wind compliance, voiding insurance or council approval.
- Non-BlueScope steel or low-quality fasteners may corrode early, especially near the coast.
- Poor design choices (too many openings, wrong roof pitch, no vermin/seal flashing) increase maintenance and heat load.
Instead, target “best-value” sheds: standardised engineering, right wind rating, minimal custom cuts, and proven cladding. That’s how to get the sheds cheapest without sacrificing safety or durability.
What Are the Best Shed Materials for Perth’s Climate?
In WA, heat, UV, and coastal corrosion are the big enemies. Durable cladding and proper coatings matter more than ever.
Colorbond vs Zincalume — Which Is Better for WA Conditions?
| Factor | Colorbond Steel | Zincalume Steel |
|---|---|---|
| Finish | Pre-painted (wide colour range), high UV resistance | Metallic (silver/grey), can heat up more in sun |
| Cost | Typically higher upfront | Usually cheaper |
| Corrosion Performance | Excellent with correct grade near coast (check warranty zones) | Good inland; may need extra care in coastal/salt spray areas |
| Aesthetics | Premium look; blends with contemporary homes | Industrial look; fine for rural/utility builds |
| Best Use | Homes, custom Colorbond garages Perth, visible carports | Rural sheds NSW & WA inland, farm machinery storage |
For coastal WA and high-UV regions, many buyers pick Colorbond for heat reflectivity and warranty support. For inland “workhorse” builds, Zincalume keeps budgets tight without sacrificing structural performance.
Pro Tip: Consider insulated roof panels or blanket insulation (R1.3–R2.5). They can drop internal temps by up to 10°C in summer and reduce condensation in winter.
How Much Do Australian Sheds Really Cost in 2024–2025?
Below are typical kit and installed price ranges (indicative, GST incl.). Final prices vary by wind region, height, openings, doors, and site works.
- Compact affordable garden shed (3×3 m): $900–$1,400 kit; $1,800–$3,000 installed
- DIY shed kits (6×3 to 6×6 m): $3,500–$10,000 kit; +$5,000–$12,000 installed
- Custom-built double garage in Perth (6×6 m, Colorbond): $8,500–$14,000 kit; $16,000–$30,000 turnkey
- Rural machinery sheds (12×6×3.6 m): $18,000–$28,000 kit; $35,000–$60,000 installed
- American barn / triple-bay sheds: $25,000–$60,000 kit; $50,000–$90,000 installed
- Affordable carports for Australian homes (6×6 m): $4,000–$9,000 installed
To compare prices on storage buildings fairly, always request the engineering, wind region, steel thickness, door/roller specs, gutters/downpipes, vermin flashing, fastener grade, and delivery/installation details.
Which Roof Style Is the Best Value for Your Site?
| Roof Style | Pros | Cons | Best for |
|---|---|---|---|
| Skillion (Monoslope) | Cheaper, simple drainage, modern look | Less ceiling volume; wind load can increase on tall walls | Urban blocks, carports, garden/workshop sheds |
| Gable | Classic look, good runoff, economical spans | More components than skillion at small sizes | Double garages, rural sheds, barns |
| Flat | Low visual impact, may be cheapest structure | Drainage and ponding must be engineered; height limits | Carports in suburbs with height constraints |
DIY Shed Kits vs Custom-Built Installation: Which Is Cheaper?
| Option | Upfront Cost | What You Handle | Best For |
|---|---|---|---|
| DIY Shed Kits | Lowest kit price | Permits, slab/piers, assembly, stormwater, electrical | Experienced DIYers/tradies, standard sizes |
| Supply + Install | Higher upfront | Builder handles install; you may manage slab/permits | Busy owners wanting a quick, compliant finish |
| Turnkey (Design–Permit–Slab–Build) | Highest upfront | Minimal effort; single warranty pathway | Custom builds, tight timelines, complex sites |
DIY can be the sheds cheapest route if you’re confident reading engineering drawings, setting out anchor bolts, and lifting frames safely. Otherwise, one rectification callout can erase the savings.
How to Get Council Approval for Your Custom Shed in WA
Most councils require planning/BA approvals for garages, larger sheds, and carports. Here’s the streamlined process in WA.
- Confirm zoning, setbacks, and height limits on your property.
- Obtain certified engineering for your wind region and site (AS/NZS 1170.2, AS/NZS 4600, NCC 2022).
- Prepare site plan, elevations, stormwater plan, and slab/piers detail (AS 2870 where applicable).
- Lodge your Building Permit (BA) with documentation and fees.
- Book mandatory inspections (footings, slab, final) as required.
Added 2024 WA wind-rating compliance notes: Many WA coastal sites need higher tie-down and hold-down capacities due to local gusts. Ensure your documentation lists Terrain Category, Shielding, Topographic Class, and Importance Level.

What Wind Rating Do I Need? (Cyclonic vs Non-Cyclonic)
Australia’s wind regions drive your design and cost. Queensland and WA’s north often fall into cyclonic Regions C/D. Inland southern areas are usually Region A (non-cyclonic).
- Region A: Most metro areas in southern states
- Region B: Some coastal/near-coastal zones
- Region C: Cyclonic (e.g., parts of QLD/WA)
- Region D: Severe cyclonic (e.g., WA’s northwest)
For North QLD, specify cyclone-rated sheds QLD engineered to AS/NZS 1170.2 with appropriate connections, bracing, and door wind locks. Verify with a Bureau of Meteorology wind regions map.
- Terrain Category: Upwind surface roughness affecting wind speeds at site.
- Importance Level: Minimum reliability class (IL1–IL4) from NCC; most sheds/garages are IL1 or IL2.
- BAL (Bushfire Attack Level): Bushfire exposure category affecting materials and openings in bushfire-prone areas.
Tip: Overspecifying a Region C shed in a Region A suburb can add hundreds to thousands. Always match the engineering to your actual site and shielding conditions.
5-Step Buying Guide for Custom Sheds in Australia

Ways to Make Your Shed the Cheapest—Without Regret
- Choose a standard size/bay spacing and common door widths.
- Reduce openings on windward walls; use one large roller vs multiple small ones.
- Pick a skillion or low-pitch gable if it suits drainage and local codes.
- Zincalume for inland/rural; Colorbond for coast-facing or street-visible builds.
- DIY concrete slab if qualified, or schedule installs off-peak.
- Order vermin seals and gutters upfront—cheaper than retrofitting.
- Confirm stormwater compliance to avoid rework.
Local Factors: Climate, Corrosion, and Energy
- Perth and WA inland: High UV and summer heat—insulation and lighter roof colours reduce heat gain. See Energy.gov.au on insulation.
- QLD cyclonic: Door wind locks, extra bracing, and certified connections add cost but are non-negotiable for safety and insurance.
- Coastal exposure: Check manufacturer distance-from-coast warranty terms; consider higher corrosion-resistance grades and stainless fasteners. See CSIRO corrosion research.
FAQs: Prices, Catalogues, Permits and More
Where can I see a shed catalogue with prices (PDF)?
Many suppliers offer a “shed catalogue with prices PDF” on request or via email signup. Ask for price ranges by wind region and slab thickness so you can compare apples with apples.
How do I get accurate prices on storage buildings fast?
Send a simple brief: plan size, wall height, roof style, openings (with sizes), wind region, and whether you need slab and stormwater. You’ll get tighter quotes, quicker.
Are there truly inexpensive shed kits near me?
Yes—look for standard-size DIY shed kits from ShedSafe-accredited suppliers. Pick local manufacturing to reduce freight, especially for steel sheds Perth, workshop sheds Brisbane, tool sheds Adelaide, and rural sheds NSW.
What’s the cheapest way to build an affordable garden shed?
Skillion roof, Zincalume cladding (inland), minimal openings, and DIY assembly on a compact concrete slab or engineered piers. Ensure fixings and hold-downs match wind region.
Do I always need a slab?
No. Some sheds use engineered piers/footings, especially on sloped or reactive sites. Your engineer will design to AS 2870 and AS/NZS 1170.2 based on soil and wind loads.
Are flat-pack imports worth it?
They may be cheaper at checkout, but check compliance with Australian Standards, availability of engineering certification, warranty support, and spare parts locally.
