Do You Need Council Approval?
In most Australian states, residential outbuildings (sheds) under 10m² and set back from all boundaries by at least 900mm are exempt from approval. However, rules vary significantly by LGA, so always check before buying. Sheds with electricity, plumbing, or habitable use have different (higher) requirements.
Pro tip: If you're close to a boundary, set back your shed by at least 1m to be safe across most councils. The extra 100mm makes a significant difference in approval risk.
Choosing a Shed
- 1 Pre-fabricated Colorbond steel kit: most popular in Australia, great value, 20-25 year lifespan, wide range of sizes
- 2 Absco/Keter polycarbonate: lighter weight, no rust, good for small garden sheds
- 3 Custom timber shed: premium look, integrates with heritage homes, requires painting
- 4 Colourbond custom-built: larger workshops, can include mezzanines, fully custom
Slab or No Slab?
Most quality sheds should be on a concrete slab. A properly prepared and poured slab prevents: floor warping, rodent entry, condensation rising from ground, and movement causing door alignment issues. Slab cost: $80–$150/m². Without a slab, use heavy-duty galvanised steel bearers set at correct height off ground.
Running Power to Your Shed
Running a dedicated circuit from your switchboard to a sub-board in the shed typically costs $800–$2,000 depending on distance. All work must be done by a licensed electrician. A sub-board in the shed with RCDs and circuit breakers is strongly recommended rather than running an extension lead permanently. A 15-amp circuit handles most workshop tools; 20-amp or 3-phase for heavy machinery.
