What is a shed kit?
A shed kit is a flat-pack steel shed delivered to your block as pre-cut, pre-punched components ready to bolt together. The frame, cladding, fasteners, flashings and engineering documentation arrive together. You (or a builder) supply the slab, the labour and the tools.
In Australia, a shed kit is a Class 10a structure under the National Construction Code, which means it is engineered for non-habitation: machinery, storage, workshop, garaging (Australian Building Codes Board, NCC building classifications). Habitable builds run as Class 1a, see the kit homes product page.
ShedDesigner kit sheds are built from 100% Australian-made BlueScope steel and engineered to AS/NZS 1170.2:2021 wind actions for your specific site. Pick a starting template from the sheds category, set the span, length, height, doors and lean-tos, then submit your design once for free comparable quotes from ShedSafe accredited dealers in your region. Choose to receive your build as a kit or fully supplied and installed.
What's in a shed kit
A genuine ShedSafe accredited kit ships with everything the structure needs above the slab.
- Steel frame: BlueScope-rolled cold-formed columns, rafters and purlins, pre-punched.
- Cladding: ZINCALUME® or Colorbond® roof and wall sheets, cut to length.
- Fasteners and flashings: structural bolts, tek screws, ridge cap, barge cap, gutter and downpipes.
- Doors: roller doors, sliding doors and PA doors per the design.
- Engineering certification: site-specific structural certification stamped to AS/NZS 1170.2:2021 for the wind region and importance level.
- Slab and footing drawings: dimensioned plans for the concreter.
- Step-by-step assembly drawings: numbered to match the labelled steel.
What is not in the kit: the slab itself, council DA or CDC fees, electrical and plumbing, and the labour to erect.
DIY versus supplied and installed
Both pathways start with the same engineered design. The trade-off is time, cost and warranty.
- DIY kit: lowest hard cost. A small-to-medium farm shed kit is realistically a two-person, two-to-five-day build with a forklift or a telehandler for the rafter lift. Expect impact driver, hex socket set, string line, magnetic level, scaffolding for anything over 3.6 m, and a teleporter for the high steel.
- Supplied and installed: the dealer's licensed crew erects the kit on your slab, typically two to ten days on site depending on size. Higher cost, faster lock-up, and the build carries the dealer's installation warranty on top of the BlueScope material warranty.
A shed kit costs from around $7,530 for a single garage to $102,610-plus for a 36 m × 15 m × 5 m industrial span (Wide Span Sheds, 2026 pricing). Steel pricing moves with supplier costs. In mid 2026 some shed suppliers passed on BlueScope price increases of around 2 to 3 per cent on kit prices. Always get a current quote rather than relying on published prices.
Why ShedSafe accreditation matters most in the kit world
The kit category is where shortcuts hurt the buyer. A back-of-truck imported kit might be cheaper today and uninsurable tomorrow. ShedSafe is the third-party accreditation programme run by the Australian Steel Institute, Australia's peak steel industry body, that audits a shed company's engineering, steel sourcing and site-specification process (Australian Steel Institute, ShedSafe Accreditation Programme). Every shed approved under ShedSafe is engineered to Australian Standards specifically for its site, including wind, snow and earthquake loads.
For cyclonic builds this is non-negotiable. AS/NZS 1170.2:2021 sets four wind regions: A (non-cyclonic, most of inland Australia), B (intermediate, parts of coastal NSW and SA), C (cyclonic, up to 220 km/h, north of roughly Bundaberg through to north WA), and D (severe cyclonic, up to 260 km/h, far north WA tip including Onslow and Port Hedland) (Standards Australia, AS/NZS 1170.2:2021; DomeShelter Australia, Wind regions of Australia). A kit not engineered for the right region will fail at council and at insurer.
Before you get quotes
100% Australian-made BlueScope Steel. Across structural framing, ZINCALUME® and Colorbond® cladding. BlueScope's COLORBOND® steel cladding for sheds and garages carries a warranty of up to 15 years against corrosion to perforation, with the exact period set by location and application (BlueScope, Garages & Sheds Warranty). Check your build on BlueScope's online warranty estimator.
ShedSafe accredited dealers, no exceptions. Every dealer on the network is third-party assessed.
One design, multiple quotes. Design the shed once, choose to receive it as a kit or fully installed, and get comparable quotes from accredited dealers in your region. Same engineering, same standard, same wind class, so the quotes you get back are directly comparable. Because the kit is designed to your dimensions rather than a fixed preset size, the engineering certification matches your actual site.

Frequently Asked Questions
How much does a shed kit cost in Australia in 2026?
Single garage shed kits start around $7,530 and large industrial shed kits run to roughly $102,610 for a 36 m × 15 m × 5 m span (Wide Span Sheds, 2026 pricing). Mid-size farm kits typically land between $12,000 and $40,000 depending on span, lean-tos, doors and Colorbond® colour. Steel pricing moves with supplier costs. In mid 2026 some shed suppliers passed on BlueScope price increases of around 2 to 3 per cent on kit prices. Always get a current quote rather than relying on published prices.
How long does it take to build a shed kit yourself?
Most small-to-medium kits are a two-person, two-to-five-day DIY build assuming a poured slab, a forklift or telehandler for the rafter lift, and basic carpentry experience. Larger spans (12 m and above) usually need three to four people and additional days. True Blue Sheds and other accredited suppliers note that pre-punched components and step-by-step drawings shorten the build, but height work over 3.6 m needs proper scaffolding (True Blue Sheds, *Shed Kits*).
Can I assemble a shed kit on my own?
Solo assembly is possible for the smallest garden shed kits but not realistic for anything over a 6 m × 6 m span. Lifting a single rafter or a 6 m roof sheet single-handed is unsafe and will damage the steel. Most ShedSafe accredited suppliers recommend two people minimum, with a forklift or telehandler for the rafter lift on anything over a 4.5 m bay. If you are working alone on the planning, you can still order the kit and engage a local builder for the lift days.
What's NOT included in a shed kit?
A typical kit covers the structure above the slab: frame, cladding, fasteners, flashings, doors, engineering certification, and slab and footing drawings. It does not cover the concrete slab itself, council DA or CDC application fees, electrical or plumbing rough-in, on-site guttering downstream of the building, or the labour to erect (True Blue Sheds, *Shed Kits*). Plan and budget the slab and council fees separately before you order.
Do warranty terms differ between a kit and a supplied-and-installed shed?
Yes. BlueScope's COLORBOND® steel warranty for sheds and garages (up to 15 years against corrosion to perforation, with the exact period set by location and application) applies the same way to both pathways (BlueScope, *Garages & Sheds Warranty*). Check your build on BlueScope's online warranty estimator. The difference is the workmanship warranty: a supplied-and-installed build carries the dealer's installation warranty on top, while a DIY kit puts assembly responsibility on the builder. If a fastener is mis-torqued or a flashing is wrongly lapped, that is a DIY issue, not a manufacturer claim.
Does ShedSafe accreditation still apply if I choose the kit option?
Yes. ShedSafe accreditation audits the company's engineering, steel sourcing and site-specification process, not the on-site labour (Australian Steel Institute, *ShedSafe Accreditation Programme*). A ShedSafe accredited kit comes with site-specific engineering certification regardless of whether you erect it yourself or use the dealer's crew. The accreditation is what your council and your insurer will look for at sign-off, kit or installed.
Can a kit shed be engineered for a cyclonic region?
Yes, when the supplier is set up for it. AS/NZS 1170.2:2021 sets cyclonic Region C (up to 220 km/h) and severe cyclonic Region D (up to 260 km/h) across northern Australia (Standards Australia, *AS/NZS 1170.2:2021*; DomeShelter Australia, *Wind regions of Australia*). A region-C or region-D kit needs heavier sections, denser fastener spacing, and cyclonic tie-downs, which adds materially to cost. A non-cyclonic kit cannot be re-classified by paperwork alone, the steel itself is different. Confirm the engineering region on the certification before you accept the quote.
Is the concrete slab included in a shed kit?
No. Almost no Australian shed kit includes the concrete slab, only the dimensioned slab and footing drawings the concreter works to. Slab specification depends on the soil class (M, H1, H2 or P under AS 2870), the wind class, and the loads from the structure. Budget the slab as a separate trade. For a single garage expect roughly $4,000 to $8,000; for a large rural shed the slab can rival the cost of the kit itself.
