When comparing shed homes or kit homes in Queensland, the same building can appear on different websites at dramatically different prices. That gap exists because those prices correspond to entirely different scopes of work. A kit-only price covers materials delivered to site. A lock-up vs turnkey build in Queensland covers entirely different levels of builder involvement — and a very different amount of work left for the buyer to manage.
Understanding this distinction is essential before any meaningful price comparison across builders is possible. The right tier depends not just on budget but on how much time, experience, and risk appetite the buyer brings to the project. Kit-Only, Lock-Up, and Turnkey each suit a different type of buyer in a different set of circumstances — and choosing the wrong one can cost far more than the apparent savings on the contract price. This guide explains each tier specifically, what the buyer is responsible for, and which option fits which situation.
Kit-Only: You Manage the Build, We Supply the Materials
A Kit-Only supply means The Shed House designs and manufactures the structural kit — engineered steel frame, roofing, cladding, windows, and doors — and delivers it to site. From that point, the buyer is responsible for all on-site work: site preparation, foundation works, frame erection, and the entire internal fitout including plumbing, electrical, and internal linings. The kit arrives; what happens next is the buyer's project.
To manage the erection phase legally, the buyer either holds an owner-builder permit from QBCC (required when total building work value exceeds $11,000) or engages a licensed builder to manage the on-site construction. According to Master Builders Queensland's guidance on choosing contracts, supply-only arrangements require a different contract form than domestic building contracts. The appropriate document for a Kit-Only supply is the HIA Kit and Transportable Homes Contract — not a standard residential building contract.
Kit-Only suits owner-builders with genuine construction experience, or buyers who already have a trusted licensed builder lined up and want the most cost-effective way to access an engineered steel kit. For the kit homes Queensland — the full range of designs and service tiers, the available floor plans span compact secondary dwellings through to large family homes. The Kit-Only supply tier is designed for owner-builders or those who have their own licensed carpenters arranged.
Lock-Up: The Builder Takes It to a Weatherproof Shell
A Lock-Up build means The Shed House completes the structural shell of the home to a weatherproof, lockable state: the frame is erected, the roof is on, external cladding is installed, and windows and external doors are fitted. At lock-up, the building is structurally complete from the outside — wind and weather tight, secure enough to leave on site overnight — but the interior remains unfinished.
There are no internal wall linings, no flooring, no plumbing rough-in, no electrical first fix, and no kitchen or bathroom fittings at lock-up stage. The buyer takes over at this point and manages all internal trades to complete the home. This arrangement suits buyers who want a licensed builder handling the critical structural and weatherproof work, while retaining control over the internal finish and cost.
Lock-Up is also a practical option for owner-builders who want a builder's stamp on the structural shell before finishing the interior themselves. The internal trades — plumbing, electrical, tiling, cabinetry — can then be engaged individually, often at better rates than a full-build contract would include. The structural integrity of the shell is certain; the buyer's involvement begins at the least structurally sensitive phase of the project.
Turnkey: Full End-to-End From Design to Handover
A Turnkey build is the full-service option. The Shed House manages the entire project from initial design through council approvals, construction, all internal trades, and final handover. The buyer receives a completed, certified, move-in ready home. There are no trades to coordinate, no approvals to lodge, and no construction phase to supervise.
Turnkey includes design and documentation, lodgement of all council and building approval applications, site preparation and earthworks, foundation and structural frame, roofing and cladding, all internal linings, flooring, kitchen and bathroom fitout, plumbing, electrical, and final certifier sign-off. Every phase is managed as a single continuous project. For buyers exploring Sunshine Coast kit home builds from Kit-Only to Turnkey, regional availability and build timelines vary by project scope and design complexity.
Turnkey is also the most appropriate tier for buyers using standard residential mortgage financing. Lenders are generally more comfortable with a single fixed-price domestic building contract than with a staged, owner-managed build where the final cost and completion date carry more uncertainty. The Turnkey Build tier includes design, council approvals, construction, all trades, and final handover — the most predictable path from first conversation to keys in hand.
Which Tier Is Right for Your Budget and Risk Appetite?
The three tiers form a clear spectrum: more buyer involvement means a lower contract price but more risk, more time, and more decisions to manage personally.
Kit-Only is the most cost-effective upfront but carries the most risk. It suits buyers with a genuine construction background, a licensed builder already arranged, and the time to manage the project through from erection to final fitout. The savings are real — but so are the risks. Trade coordination problems, delays, and defects on an unsupervised project can consume the apparent savings quickly.
Lock-Up reduces the risk on the structural phase — the most technically demanding and consequential part of the build — while keeping the internal fitout in the buyer's hands. It suits buyers comfortable project-managing interior trades but who want a professional handling the frame, roof, and cladding. For buyers comparing shed home designs available across all three service tiers, the same floor plans are generally available regardless of which service tier is selected.
Turnkey suits buyers with limited construction knowledge, limited time for project management, or those using standard residential financing. It is the most expensive tier on paper, but the final cost and delivery timeline are also the most predictable. The honest question is not which tier costs least — it is which tier matches what the buyer can realistically manage.
QBCC Implications: What Each Tier Means for Permits and Insurance
The service tier determines who holds the QBCC builder's licence and what compliance obligations the buyer carries.
Under a Turnkey or Lock-Up engagement, The Shed House holds the QBCC builder's licence for the work performed. The buyer does not need an owner-builder permit for that scope. Home Warranty Insurance applies to building work over $3,300 performed by a licensed builder, protecting the buyer against construction defects in the completed structure.
Under a Kit-Only arrangement, the buyer takes on responsibility for the on-site building phase. According to the QBCC owner-builder requirements, an owner-builder permit is required when the total value of on-site work exceeds $11,000. Importantly, only one such permit can be issued to an individual within any 6-year period — a constraint that matters for buyers who have used an owner-builder permit on a previous property in the recent past.
One further consequence applies specifically to the Kit-Only tier when the buyer manages erection themselves: the owner-builder permit notation is recorded on the property's title. This notation does not apply to Turnkey or Lock-Up builds, where The Shed House holds the builder's licence throughout. For frequently asked questions about build tiers and the QBCC permit process, the most common scenarios are covered in detail.
Work Out Which Tier Suits Your Project
The lock-up vs turnkey decision in Queensland comes down to a straightforward question: how much of the project are you genuinely equipped to manage yourself? The right tier is the one that honestly matches your experience, your schedule, and your risk tolerance — not the one with the lowest upfront number.
