10×10 Shed Australia: Pricing, Council Approval, Colorbond Options (2025 Guide)
A 10×10 shed—often written as a 10 x 10 storage shed, 10×10 garden shed, or 10 10 building—is a versatile, compact footprint that suits most suburban blocks while still swallowing bikes, tools, and lawn gear. If you want a durable, council-approved shed in WA, VIC, NSW, or QLD, this guide distils what top Australian suppliers cover—then goes deeper on engineering, local climate, and approvals.

What can you fit in a 10×10 shed?
- Two adult bikes, mower, whipper snipper, garden tools, plus shelving
- Small workbench and pegboard for DIY
- Seasonal storage: camping gear, eskies, boxes, kids’ toys
- Not ideal for a car; consider a custom-built double garage in Perth or single garage if vehicle storage is needed
What Are the Best Shed Materials for Perth’s Climate?
Perth heat, intense UV and coastal air demand durable cladding and fasteners. For a 10×10 garden shed near WA’s coast, Colorbond steel on a galvanised steel frame is the premium choice. Inland regional WA can also perform well with Zincalume, but be mindful near the surf zone or estuaries.
| Factor | Colorbond (BlueScope) | Zincalume | Best Use |
|---|---|---|---|
| Finish | Painted, UV-stable coating; many colours | Alu-zinc coating, silvery appearance | Colorbond for urban aesthetics |
| Coastal resistance | Excellent with correct grade and detailing | Good inland; avoid harsh coast unless upgraded | Colorbond near coast |
| Heat reflectivity | Thermatech colours can reduce heat gain | Reflective but can glare | Colorbond light colours in Perth |
| Price | Higher initial cost | Generally cheaper | Zincalume for inland budget builds |
| Warranty | Long warranties when installed to spec | Strong warranties inland | Either, per site conditions |
How much does a 10×10 shed cost in Australia (2025)?
Indicative ranges for a 3.0 m x 3.0 m Colorbond steel shed kit (excluding slab, delivery, install):
- Entry-level DIY shed kits: $1,600–$2,400
- Mid-range (Colorbond cladding, better hardware): $2,400–$3,800
- Premium custom-engineered (higher wind ratings, insulation, windows, roller door): $3,800–$6,500
Add: concrete slab ($900–$1,800+ depending on site and thickness), delivery, and install if not DIY. Regional freight and cyclonic engineering in QLD can add 10–25%.
Design choices that matter on a 10×10 shed
Roof profile: flat vs gable
| Aspect | Flat/Skillion | Gable |
|---|---|---|
| Looks | Modern, low profile | Classic, suits most homes |
| Water run-off | Single direction; needs good gutter/downpipe | Two directions; often better drainage |
| Headroom | Lower internal volume | Extra centre height; better for storage |
| Wind performance | Lower sail area | Excellent when engineered with proper tie-downs |
| Cost | Generally cheaper | Slightly higher |
Access and security
- Doors: single hinged, double hinged, or compact roller door. Roller suits tight driveways.
- Hardware: upgrade to stainless screws near coast; add lockable hasps or deadbolts.
- Windows/skylights: polycarbonate skylights and aluminium windows add light. Use security mesh if needed.
Ventilation and comfort
- Roof vents or whirlybirds prevent hot air build-up
- Insulation: foil-backed blanket for condensation control; bulk insulation for comfort
- Seal with vermin flashing; specify quality guttering and downpipes
DIY kit vs custom-built
| Aspect | DIY Shed Kits | Custom-Built (Supply & Install) |
|---|---|---|
| Price | Lowest upfront | Higher, includes labour |
| Speed | Depends on your time/skills | Faster; project managed |
| Approvals | You handle council | Provider manages drawings/engineering |
| Finish | Good if careful | Consistent, warrantable |
| Customisation | Limited to kit options | High: height, doors, windows, lining |
Engineering and compliance for Australian conditions
All sheds should be engineered to the NCC 2022 and AS/NZS 1170.2 wind actions for your site’s wind region, terrain category, topography, and shielding. In QLD cyclonic zones, a 3×3 m shed may still require cyclone-rated detailing: upgraded frames, hold-down bolts, and door bracing.
- Wind Regions: A (most of southern Australia), B (some coastal), C and D (cyclonic QLD/WA)
- Tie-downs: engineer-specified anchors or chem-set bolts to the slab
- BAL: ember seals, mesh to vents; consider non-combustible linings where required
- Corrosion zones: hot-dip galvanised frames and marine-grade fasteners near the coast
Added 2024 WA wind-rating compliance notes: Many councils across Perth and regional WA expect certified drawings showing wind region, terrain, and footing/slab design. Ensure your supplier’s engineering specifically notes Region A or B and any topographic speed-up if you’re on a ridge or escarpment.
Do I need council approval for a 10×10 shed?
Most councils allow small sheds exempt or fast-tracked if they meet size, height, and boundary setbacks. However, rules vary by state and LGA. When in doubt, get a council-approved shed in WA, VIC, NSW or QLD to avoid compliance issues at resale or inspections.
How to Get Council Approval for Your Custom Shed in WA
- Confirm planning rules: setbacks, maximum height, site coverage
- Order engineered plans (AS/NZS 1170.2) and slab design
- Prepare a site plan with contours, drainage, and services location
- Lodge building permit with your LGA; respond to RFIs promptly
- Book inspections if required (footings/slab, final)
Check your local council’s thresholds. Some permit a small shed as exempt development if under certain height/area, but cyclonic or bushfire-prone areas may still require permits.

5-Step Buying Guide for Custom Sheds in Australia
- Define use-case: storage only, workshop, or hobby space? Consider power, light, and ventilation early.
- Pick materials: Colorbond for coast/urban durability, Zincalume inland. Match gutters and downpipes.
- Engineer for site: wind region, BAL, and slab thickness. Request AS/NZS 1170.2 compliance in writing.
- Plan approvals: get a council-approved shed (WA) or applicable state approvals to protect resale value.
- Install like a pro: level pad, correct anchors, sealed flashings, and a quality door set for long-term security.
Frequently asked questions
Is a 10×10 garden shed big enough for a ride-on mower?
Yes for compact models, but measure turning circle and door width. A roller door is easier than double hinged for wider mowers.
What slab do I need for a 3×3 m shed?
Commonly a 100 mm concrete slab with F62 mesh on compacted subgrade; thicken edges as per engineering. Confirm load if adding shelving or a workbench.
Can I DIY a 10×10 shed?
Yes. Many Australians choose DIY shed kits. Read plans thoroughly, use proper PPE, square and plumb the frame, and anchor to spec.
Which Colorbond colours are cooler?
Lighter colours with Thermatech technology reflect more heat. Combine with roof insulation and vents for best results.
