It’s a fair question, and most of the answers online are written by people selling kits, which doesn’t help much.
Short version: a kit is the cheapest way to get a proper engineered steel building on your property, and the savings are real. But the kit price isn’t the project price, and there are situations where a kit is the wrong call. Here’s the honest breakdown.
What a Shed Kit Actually Is
A shed kit is a steel building manufactured to your dimensions, cut to length, packed and delivered to your site as a set of parts with engineered plans and instructions.
It isn’t a flatpack from a hardware store, and it isn’t a builder turning up with a trailer full of raw steel to cut on site. Everything arrives pre punched and pre cut to suit the plans, so the job on site is assembly rather than fabrication.
That’s the whole reason the price works. The engineering is done once across thousands of buildings, the steel is rolled in volume, and nobody is standing in your paddock working out where the holes go.
What’s In the Box
For our shed kits, that’s the structural frame, the cladding, gutters and downpipes, all fixings and fasteners, and engineer designed plans and certification for your site.
The certification is the part people skim past and shouldn’t. Those plans are what your council or certifier assesses, and they’re drawn for your address, your wind region and your terrain, not copied off a generic set. Without them you don’t have an approvable building.
You can also spec the shed properly rather than take what’s on the shelf. Sizes from 6m x 6m up to 18m x 40m, built to the millimetre, with your choice of roof pitch, cladding profile and colours across the full COLORBOND range or Zincalume.
What’s Not In the Box
This is where budgets blow out, so it’s worth being blunt about it.
The slab. You supply it. Concrete, reinforcement, prep and pump if access is tight.
The labour. You supply that too, either by hiring a shed erector or doing it yourself if you’ve got the skills and the gear.
Site works. Clearing, levelling, cut and fill, drainage and access. On a flat block this is minor. On a slope it isn’t.
Approval costs. Council or certifier fees, and any reports the block requires.
Fit out. Power, lighting, insulation, concrete aprons, benches, shelving. None of that comes with a shed, and all of it costs money.
A kit price is a kit price. Anyone quoting you a “shed” for the same number as a kit is either including those things or they aren’t, and you need to know which.
The Three Ways to Get a Shed Up
Hardware store flatpack. Cheap, small, and fine for storing the mower and the bikes. Light gauge steel, limited sizes, and generally not the answer if you want to park a vehicle in it or expect it to still be standing in twenty years of Australian weather. Different product, different job.
Engineered kit plus your own builder. The middle road, and what most people end up doing. You buy the kit, you organise the slab and the erector. More coordination on your part, and the lowest total cost for a serious building.
Turnkey supply and install. Someone handles the lot, slab included, and hands you the keys. Costs more because you’re paying for project management and margin on every trade. Worth it if you’re time poor, interstate, or simply don’t want to chase concreters.
We can organise council approval and the build across the Gold Coast, Logan, Jimboomba and Brisbane areas. Outside that we supply the kit and can point you to erectors we’ve worked with.
Where the Money Actually Goes
On a typical domestic shed, the kit is the biggest single line, but it’s usually well short of the whole project once the slab, the erection and the approvals are in.
The proportions shift depending on the job. Big open span buildings put more of the cost into the kit. Small sheds on difficult sites put more into the slab and site works than people expect, because a concreter’s minimum callout doesn’t shrink just because the shed is little.
The point is to budget for the project, not the kit. Ask for the kit price, then get a concreter and an erector out before you commit, so you’re looking at a real number.
When a Kit Is Worth It
A kit stacks up when you want a building that’s engineered, certified and built to last, and you’re prepared to organise a couple of trades.
It’s the right call if you want a specific size rather than whatever’s in stock. If you’re in a high wind or cyclone area and need the engineering done properly for your site. If you’re putting up something substantial, a workshop, a machinery shed, a barn, where a flatpack was never going to cut it.
It also suits anyone who wants to stage the job. Get the shell up now, do the power and the fit out later when the budget’s recovered.
And if you already know a good builder, or you’re on the tools yourself, you’re capturing the labour margin rather than paying it.
When It Isn’t
Fair’s fair, there are times a kit is the wrong choice.
If you want a small garden shed for a mower and a wheelbarrow, buy the flatpack. An engineered kit is overkill and you won’t get value out of it.
If you genuinely have no time and no appetite for coordinating trades, a turnkey build might cost more but it’ll cost you less grief. Kits sitting on site for three months waiting on a builder are a real thing.
If the block has serious problems, steep fall, poor access, a flood or bushfire overlay, sort that out and get advice before you buy anything. The kit isn’t the hard part of that job.
And if you’re planning to live in it, that’s a different building entirely. A kit is a Class 10a structure, and turning one into a dwelling is a much bigger process.
Good Kit vs Cheap Kit
Not all kits are the same building with a different sticker on it.
Steel. Australian BlueScope steel versus imported. Gauge and section size matter, and they’re the easiest place for a cheap quote to find savings you can’t see in a brochure.
Engineering. Site specific certification versus a generic set of plans. Ask which you’re getting, because council will find out either way.
Accreditation. ShedSafe accreditation, run by the Australian Steel Institute, means the kits have been independently checked against the standards. We’re accredited and members of the ASI Steel Sheds Group.
What’s counted as included. Gutters, downpipes, flashings and fasteners should all be in there. Some quotes leave bits out and let you find out on delivery day.
Who you ring when something’s wrong. We’ve been supplying kits since 2001 and we’re family owned. There’s a phone number and someone who knows your job on the end of it.
How to Compare Quotes Properly
Four questions and you’ll separate the real quotes from the optimistic ones.
What wind region has this been priced to? Prices on our shed kit specials page are Region A unless noted, and a quote priced to the wrong region isn’t cheaper, it’s just wrong.
What steel and what gauge? Does it include engineered plans and certification for my address? And what’s excluded, spelled out?
Then compare on like for like. Two quotes that look thousands apart usually aren’t quoting the same building.
