What does a 10 sqm shed fit, and what sizes are common?
A 10 square metre shed is the sweet spot for Aussie backyards. Typical footprints include 3.0 × 3.3 m, 2.5 × 4.0 m, or 3.2 × 3.2 m with an internal clearance of ~2.1–2.4 m eaves height. It’s ideal for:
- Motorbike or two pushbikes plus a workbench
- Garden gear, whipper snippers, and a 4-stroke mower
- Compact hobby workshop with shelving and pegboard
- Small “home gym” zone with rubber mats and storage
Or, explore a 3×3 Garden Shed for smaller installations.
If you’re eyeing vehicle storage, consider a custom-built double garage in Perth or a single-bay garage shed Brisbane-wide. For a 10 sqm footprint, think “secure storage and projects”, not parking.
What are the best shed materials for Perth’s climate?
For WA’s high UV and heat, Colorbond steel (by BlueScope) is the proven performer. Zincalume is excellent too, but Colorbond’s paint system handles radiant heat, chalking and fade better in many suburban installs.
Colorbond vs Zincalume — Which is better for WA conditions?
| Factor | Colorbond Steel | Zincalume Steel |
|---|---|---|
| Coating & Finish | Painted, baked-on finish; wide Colorbond palette | Metallic alloy coating; silver/grey appearance |
| Heat & UV Resistance | Excellent; suitable for Perth and Pilbara sun | Very good, but can reflect glare |
| Corrosion Resistance | Excellent, especially with marine-grade options | Excellent; watch fasteners in coastal C3–C4 zones |
| Aesthetics (Aussie homes) | Matches roofs/fences; premium look | Industrial look; budget-friendly |
| Cost (kit level) | $$ | $ |
| Warranty | BlueScope warranty when installed per spec | BlueScope warranty when installed per spec |
In coastal WA, specify marine-grade fasteners, proper edge distances, and vermin-proof flashings to limit salt ingress. Ask for Bluescope steel warranty paperwork at handover.
How much does a 10 square meter shed cost in Australia (2025)?
- DIY shed kits (Zincalume): from ~$1,200–$2,400
- DIY shed kits (Colorbond): from ~$1,600–$3,200
- Installed custom Colorbond sheds: typically $3,800–$7,500+ depending on wind rating, doors, windows and slab
- Concrete slab (100–120 mm with mesh, MPA 25–32): ~$110–$180/m² regionally variable
- Upgrades: insulation, whirlybirds, skylights, roller door, powder-coated accessories: $500–$2,000+
Costs vary by region (steel freight, labour, and engineering). Recent market notes from the 2025 Australian Steel Market Outlook and the HIA Outdoor Structures report indicate stable supply with pockets of higher transport cost in regional WA/QLD.
Do I need council approval for a 10 sqm shed?
Each state has thresholds for “exempt” or “complying” development. Height, location, wind region and use matter as much as area.
How to get council approval for your custom shed in WA
- Check R-Codes and local planning policy for setbacks and eaves height.
- Small sheds can be exempt, but many councils still require a BA2 (certified) or BA1 (uncertified) building approval if fixed to a slab.
- Provide site plan, engineering (AS/NZS 1170.2 wind actions), tie-down schedule, and slab details.
- Added 2024 WA wind-rating compliance notes: Many metro Perth sites are N2–N3. Coastal or hilltop sites may need higher ratings.
- Ask about council-approved sheds WA packages to streamline documentation.
Fast-track approvals in NSW and VIC
- NSW: Some 10 sqm sheds qualify as exempt development if size, height and boundary setbacks are met. Otherwise consider CDC (Complying Development Certificate).
- VIC: Check Victorian Planning Provisions; small outbuildings may be exempt, but Building Permit often required if on a slab or near boundaries.
QLD and cyclonic areas
- Non-cyclonic SEQ sites are often N2–N3. Northern QLD may be C2–C3 and always need engineered cyclone-rated sheds QLD details, plus Form 15/16 certifications.
Always confirm with your council or a private certifier. See official guidance at the Housing Industry Association (HIA), Master Builders Australia (MBA), and the Australian Standards catalogue (AS/NZS).
Which roof style suits a 10 sqm shed?
| Roof Style | Best For | Pros | Considerations |
|---|---|---|---|
| Flat (low pitch) | Tight sites, under eaves height limits | Simple, cost-effective | Drainage crucial; limit in heavy rain zones |
| Skillion (mono-pitch) | Modern look, solar-ready roofing | Great water run-off, easy guttering/downpipes | Check height on high side near boundary |
| Gable | Classic backyard look | Good airflow, headroom | Slightly higher material cost |
DIY shed kits vs custom-built (installed)
| Option | Who it suits | Pros | Watch-outs |
|---|---|---|---|
| DIY shed kits | Confident DIYers with tools and time | Lower cost, quick delivery | Approvals, slab, wind-rated fixings are on you |
| Custom-built (turnkey) | Time-poor owners, premium finish | Design flexibility, engineering, install handled | Higher upfront cost |
Wind ratings, tie-downs and engineering (small shed, big forces)
Even a 10 sqm shed must meet AS/NZS 1170.2 (wind actions). Your site’s wind classification (N1–N3 non-cyclonic, C1–C3 cyclonic) dictates frame spacing, sheeting gauge, and anchor design.
- Frame: RHS or C-section portal frame with engineered span tables
- Tie-downs: Cyclone tie-down kits in C regions; correct embedment depth for anchors
- Footings: Concrete slab (thickened edge beams) or concrete pier footings
- Fasteners: Class 4 coated screws in coastal C3–C4 zones
- Documentation: Wind report, engineering certificate, and fixings schedule
Check your wind region and cyclone history with Bureau of Meteorology data (BOM climate) and ensure your supplier provides site-specific engineering.
Heat management: insulation, ventilation and comfort
- Roof blanket/sarking + R1.3–R2.5 insulation batts
- Insulated roof panels or anti-condensation foam under Colorbond
- Whirlybirds, ridge vents, and louvre windows for crossflow
- Light-colour Colorbond for lower solar absorption
Pro Tip: Did you know using insulated roof panels can reduce internal shed temperatures by up to 10°C in summer? Pair with whirlybirds and light roof colours for best results.
For energy-savvy builds (solar-ready roofing, LED lighting), see guidelines at Energy.gov.au.

Frequently asked questions
What slab do I need for a 10 sqm shed?
Commonly a 100–120 mm slab, MPA 25–32, SL72 mesh, with thickened edge beams per engineering. Allow fall to door threshold and plan stormwater.
How long does installation take?
DIY: 1–2 weekends with two people. Pro install: 1–2 days plus slab cure time (7–14 days before load).
Can I go right on the boundary?
Often no—setbacks apply. Fire separation and wall heights can trigger permits. Check local planning rules first.
Is a 10 sqm shed exempt from approval?
Sometimes—depends on state, height, location, and slab. Always verify with your council or certifier.
Colorbond or Zincalume for coastal sites?
Both are proven. Use marine-grade fasteners, sealed edges, and regular wash-downs. Colorbond offers colour stability and better aesthetic matching.
5-step buying guide for custom sheds in Australia
- Define use-case: garden gear, hobby space, farm machinery storage, or small workshop.
- Pick materials: Colorbond vs Zincalume comparison, fasteners for your corrosion zone.
- Confirm site conditions: wind rating (N/C), BAL, soil class, stormwater path.
- Sort approvals: drawings, engineering, and any state-specific forms (CDC NSW, BA1/BA2 WA, Form 15/16 QLD).
- Book install and slab: sequence concrete, delivery, erection, and final checks.
Technical checklist (Australian conditions)
- Standards: AS/NZS 1170.2 (wind), AS/NZS 4600 (cold-formed steel), AS 3959 (BAL where relevant)
- Hardware: cyclone tie-downs in C regions, Class 4 screws, proper edge distances
- Drainage: gutters, downpipes sized for local rainfall intensity (BOM data)
- Thermal: sarking/insulation, ridge vent or whirlybird, light-colour roof for heat
- Electrical: RCD-protected subcircuit, LED task lighting, solar-ready roofing if needed
For deeper industry guidance, see the Australian Steel Institute (ASI) and recent construction insights from HIA (HIA resources). BOM climate zone context helps select roof pitch and drainage sizing (BOM design rainfalls).
