If you’ve searched “6×6 shed price” you might mean either a compact 6×6 ft garden shed, or a large 6m x 6m double garage. This guide covers both, with Australian pricing, wind-rating requirements, and council pathways—plus expert insights for steel sheds Perth, rural sheds NSW, and cyclone-rated sheds QLD.
How much does a 6×6 shed cost in Australia?
Indicative 2025 prices in AUD (materials and labour have stabilised but remain region-dependent):
- 6×6 ft garden shed (about 1.8m x 1.8m)
- DIY kit (Zincalume): $450–$950
- DIY kit (Colorbond): $700–$1,400
- Installed on pavers/slab: $1,200–$2,500+
- 6m x 6m double garage (Colorbond steel)
- DIY kit only: $6,500–$14,000 (wind region, BMT, roof style and doors drive variance)
- Supply + erect (no slab): $12,000–$25,000
- Turnkey incl. slab, gutters, roller doors, permits: $18,000–$38,000+
- Location/wind effects: Region C or D (wind-rated sheds for cyclonic areas) typically add 20–40% for extra hold‑downs, purlins and engineering.
Comparable sizes many buyers price-check:
- 6m x 8m shed prices: DIY kit $8,500–$18,000; turnkey $22,000–$45,000+
- 7×9 shed (approx. 7m x 9m): DIY kit $12,000–$26,000; turnkey $32,000–$65,000+
- 5 bay shed (farm machinery storage): Highly variable; budget $55,000–$140,000+ depending on spans, doors and wind region
Note: All ranges are guides only. Site access, engineering, soil class and scope cause significant swings. Ask for a fixed, engineered quote.
What drives 6×6 shed price?
1) Steel specification and profile
- Cladding BMT (base metal thickness): 0.35 / 0.42 / 0.48 mm
- Framing: C/Z purlins (100–150+), high-tensile galvanised RHS, or cold-formed portal frames
- Coatings: Colorbond vs Zincalume (see comparison table below)
- Roof style: gable roof shed vs skillion roof shed (skillion often cheaper, gable better headroom)
- Accessories: anti‑condensation blanket, vermin‑proofing, whirlybirds, ridge vents, insulated panel roofing
2) Wind rating and engineering
Cyclonic designs add purlin density, heavier connections, extra bracing and deeper footings. If you’re in North QLD or coastal WA, insist on cyclone-rated sheds QLD or council-approved sheds WA with certified engineering.
3) Doors, windows and automation
- Roller doors (2,400–3,000 mm widths) vs panel-lift; wind‑lock options in cyclonic regions
- Motorisation, remotes, safety beams, keyed alike locks and heavy‑duty roller doors
- PA doors, aluminium windows, security screens and bushfire ember seals
4) Foundations, slab and site works
- Cut/fill, export, rubble base, drainage and stormwater tie‑ins
- Thicker slabs for hoists or garage workshop combo setups
5) Finish and corrosion environment
- Coastal/corrosion categories (C3–C4) may require Colorbond Ultra or upgraded galvanising
- BAL (bushfire) requirements may change vents, mesh, and glazing (AS 3959)
6) Build method
- DIY shed kits: cheapest, fastest lead times, you manage permits and trades
- Supply + erect: builder erects; you arrange slab/electrical
- Custom-built turnkey: bespoke design and end‑to‑end approvals; highest cost, least hassle
What Are the Best Shed Materials for Perth’s Climate?
Perth summers are hot and dry with high UV; coastal suburbs also face salt air. Prioritise heat-reflective roofing, compliant ventilation and corrosion resistance for custom Colorbond garages Perth and steel sheds Perth.
Colorbond vs Zincalume — Which Is Better for WA Conditions?
| Attribute | Colorbond | Zincalume | Best for |
|---|---|---|---|
| Coating | Pre-painted steel (polymer topcoat over alloy‑zinc) | Aluminium‑zinc alloy (no colour topcoat) | Design flexibility vs raw value |
| Heat/UV | Cooler colours offer solar reflectance; superior UV stability | Reflective when new; can dull over time | High-UV areas like Perth |
| Coastal resistance | Colorbond Ultra recommended within ~200–400 m of surf | May need heavier galvanising/maintenance near coast | Coastal WA/QLD sites |
| Aesthetics | Wide Colorbond palette, matches homes/carports | Industrial metallic finish | Street-facing garages |
| Cost | $$–$$$ | $–$$ | Budget builds/DIY |
| Warranty | Typically strong warranties when installed to spec | Strong but depends on environment | Long-term performance |

Do I need council approval for a 6×6 shed?
Most 6m x 6m garages are Class 10a structures and require building approval. Smaller 6×6 ft garden sheds can be exempt under state “minor structures” rules if they meet size/placement criteria. Always check local planning overlays, setbacks and easements.
How to Get Council Approval for Your Custom Shed in WA
- Confirm zoning, setbacks and open space with your council (planning). Corner blocks and R‑Codes matter.
- Obtain site plan, elevations and certified engineering to AS/NZS 1170.2, AS 4100/4600 and slab to AS 2870.
- Lodge Building Permit (BA1/BA2) with owner’s consent, energy exemptions (often applicable to Class 10a), and specs for gutters/stormwater.
- Construct with registered installer; keep on‑site the approved plans, engineering and certificates.
- Finalise stormwater and compliance sign‑off (where applicable).
Added 2024 WA wind-rating compliance notes: WA coastal and north‑west sites may fall in Regions B–D. Your engineer will confirm region, terrain category and shielding. Designs must reflect these to pass a BA1/BA2 check for council-approved sheds WA.

DIY shed kits vs custom-built sheds
| Factor | DIY Shed Kits | Custom-Built (Supply + Erect/Turnkey) |
|---|---|---|
| Upfront cost | Lowest | Higher |
| Approvals | You manage permits, engineering, slab | Builder often handles approvals |
| Risk/compliance | On you to meet NCC/AS standards | Installer accountable |
| Lead time | Fast if standard kit in stock | Longer for custom engineering |
| Finish level | Basic; upgrade as you go | Integrated gutters, automation, lining |
| Best for | Confident DIYers, regional buyers | Busy owners, premium builds |
5‑Step Buying Guide for Custom Sheds in Australia
- Define the use: two cars, garage workshop combo, farm machinery storage or storage only. Plan door widths and internal clearance.
- Confirm your wind region and bushfire BAL. Ask for engineering to AS/NZS 1170.2 and AS 3959 if applicable.
- Choose materials: Colorbond vs Zincalume comparison, BMT, anti‑condensation blanket, insulation, ventilation and gutters.
- Budget inclusions: slab thickness, stormwater, power, automation, lean‑to carport addition or affordable carports for Australian homes.
- Compare quotes apples‑to‑apples: roof style, doors, windows, wind rating, site works and warranties. Ask for an itemised inclusions list.
Popular 6×6 configurations and use‑cases
- 6×6 ft garden shed: mower/tools; bolt to concrete; quick DIY
- 6m x 6m double garage steel building: two cars plus storage; add custom carports Melbourne for extra cover
- 6m x 6m workshop: higher eaves, skillion roof for racking and benches
- Rural sheds NSW: upgrade to larger spans or add a 5 bay shed for tractors/utes
Multi-Vehicle Storage
If you need covered space for more than two vehicles or larger vehicles like utes and vans, consider multi-bay carports or extended sheds. For larger vehicle solutions, our Triple Carport Australia covers custom sizing and approvals.
FAQs
Is 6m x 6m big enough for a double garage?
Yes for two medium cars with modest storage. If you want benches or a hoist, consider 6m x 7m or 6m x 8m.
Do I need a concrete slab?
Most 6m x 6m garages require an engineered slab or piers and a slab. Small 6×6 ft sheds can sit on pavers or a smaller slab if allowed.
How long does installation take?
Garden sheds: 2–6 hours. 6m x 6m garages: 2–5 days for the shell once slab is cured, plus slab curing (7–28 days).
What wind rating do I need?
Your site’s wind region (A–D), terrain and shielding set design pressures per AS/NZS 1170.2. Ask your supplier for a site‑specific engineering certificate.
Are cyclone-rated sheds more expensive?
Yes—typically 20–40% more for stronger connections, bracing and wind‑lock doors, but they’re essential for compliance and safety.
Can I add solar or insulation?
Yes. Many owners add roof insulation and 3–6 kW solar. Ensure purlin capacity and roof fixings meet the panel mounting loads.
What about termites?
Steel framing is termite‑resistant. Still treat slab penetrations and maintain perimeter barriers as per local requirements.
What are current lead times?
Standard kits: 1–4 weeks. Custom-engineered sheds: 4–10 weeks depending on season and region. Order ahead of wet season in QLD/NT/WA north.
