How big is a 12×8 shed in Australian measurements?
A 12×8 shed translates to roughly 3.6 x 2.4 metres. It fits easily in most suburban backyards and suits:
- Garden gear and mower parking (12×8 garden shed)
- Bikes, surfboards and camping gear (12×8 storage shed)
- Compact hobby workshop with mezzanine storage shelf
- Pool pump enclosure plus pool toys
Tip: Allow minimum 700–900 mm clearance around the footprint for gutters, downpipes and maintenance access. Check roller door clearance if you intend to store taller items or add a small racking bay.
What are the best shed materials for Perth’s climate?
In WA, longevity and heat are the big issues. Powder-coated, baked-on Colorbond steel cladding on a galvanised frame is the industry staple. Zincalume is also common for cost-conscious buyers. In coastal suburbs (within ~1 km of surf), step up to Colorbond Ultra or specify enhanced corrosion coatings.
Colorbond vs Zincalume — Which Is Better for WA Conditions?
| Factor | Colorbond (incl. Ultra for coastal) | Zincalume |
|---|---|---|
| Heat performance | Choice of solar-reflective colours helps reduce heat gain | Reflective when new, may dull over time |
| Corrosion resistance | Excellent; Ultra grade recommended for coastal WA | Good inland; less ideal in marine zones |
| Aesthetics | Wide colour range to match Colorbond roofs/fences | Silver/metallic look only unless painted |
| Cost | Higher upfront, strong lifecycle value | Lower upfront, budget-friendly |
| Resale appeal | High for premium homes/investments | Moderate |
Pro Tip: Did you know using insulated roof panels can reduce internal shed temperatures by up to 10°C in summer? Pair with ridge vents or whirlybirds for best results in Perth heat.
