Sheds n Homes — Shed Building in Balga

A basic 6x3m Colorbond garden shed costs $2,000–$4,000 installed. A 6x9m workshop shed costs $5,000–$12,000. A large garage-style shed with concrete slab (9x6m) costs $8,000–$20,000 all-up. Premium liveable sheds or converted workshops with insulation, lining, and power cost $20,000–$60,000+

Requirements vary by state and council. Most councils allow one shed under 10m² without approval. Larger sheds generally require a building permit, and some require a planning permit depending on the zoning, height, and proximity to boundaries. Sheds in rural areas have more generous thresholds. Always check with your local council before purchasing a shed.

Kit sheds (from Shed Boss, Ranbuild, CoolDry, Steelbuilt) are pre-engineered standard sizes ordered from a catalogue and assembled by a contractor — fast and cost-effective. Custom sheds are engineered to your specific dimensions, roof pitch, and wind/snow loading — necessary for non-standard sites, council requirements, or unusual dimensions.

A concrete slab provides the most stable, termite-resistant, and durable base for any shed. Alternatives include compacted gravel (suitable for garden sheds only), timber bearers on concrete footings (raised floor for workshop sheds), or steel shed feet on concrete piers. Council permits often specify the required base type for your shed size.

In cyclone-prone areas (northern QLD, northern WA, NT), sheds must be engineered to withstand cyclone wind loads and comply with AS/NZS 4600 and local building codes. These require heavier steel, closer purlin spacing, and engineered footings. A cyclone-rated 6x9m shed costs 20–40% more than the same shed in a non-cyclone area.
