Whether you call it a 10×10 shed, 10 × 10 storage shed, 10 by 10 garden shed, or a 3x3m Colorbond shed, this size is Australia’s most popular backyard footprint. Below, you’ll find local guidance for Perth heat, QLD cyclones, NSW rural sites, and tight Melbourne blocks—plus design, cost, approvals, and build options that match or beat top competitors.
What size is a 10×10 shed in Australia?
Most Aussies planning a 10×10 shed mean 10 feet by 10 feet. In metric, that’s roughly 3.05m × 3.05m. Most suppliers round to a standard 3.0m × 3.0m module. Wall height typically ranges from 2.1m to 2.4m; 2.7m is common if you’re storing taller gear or using a roller door.
- Footprint: approx. 9 m² usable space
- Typical fit-outs: garden tools, bikes, mower, pool gear, compact workshop bench
- Popular use-cases: 10×10 garden shed, pool pump shed, motorcycle garage, hobby workshop
What Are the Best Shed Materials for Perth’s Climate?
For WA conditions—high UV, salty coastal air, and heat—most homeowners choose a Colorbond steel shed with galvanised cold-formed framing. Zincalume is also common. Here’s how cladding choices compare for WA and similar coastal sites.
Colorbond vs Zincalume — Which Is Better for WA Conditions?
| Feature | Colorbond steel | Zincalume steel |
|---|---|---|
| Durability in coastal air | Excellent with correct maintenance; choose suitable grade for distance to surf | Very good, but can show patina; typically not as colour-stable near coast |
| Colour choices | Extensive Colorbond palette; matches modern builds | Silver/metallic only; can be over-painted |
| Heat reflectivity | High in lighter colours; Thermatech in many colours reduces heat gain | High reflectivity; can be glary |
| Warranty | BlueScope warranties up to 20–36 years (location and product dependent) | Comparably strong warranties; always check site conditions |
| Street appeal | Premium look; best for visible areas | Budget-friendly, utilitarian |
Will a 10×10 shed meet wind and cyclone ratings in my region?
Wind design is non-negotiable. In Australia, sheds are engineered to AS/NZS 1170.2 Wind Actions, using wind regions A–D (C and D are cyclonic). Many councils also reference AS 4055 categories for housing sites (N1–N6; C1–C3 in cyclonic zones) and AS/NZS 4600 for cold-formed steel members.
- QLD North and coastal WA often require cyclone-rated sheds (Region C/D). Seek cyclone-rated sheds QLD and engineered tie-down details.
- Perth metro is typically Region A, but exposure categories and terrain matter for uplift pressures.
- Rural sites (NSW/SA/QLD) can have higher site winds; ensure engineering certificates match your address.
How much does a 10×10 shed cost in 2025?
