What prefabricated home packages cost

From Modular Living Australia — the independent knowledge base Last updated: 8 Oct 2026

A prefabricated kit or panelised package buys components rather than a finished house: one supplier publishes structure-only packages from about A$35,000 for one bedroom to A$95,000 for four bedrooms, and another a structure-only rate of A$2,600–A$3,000 per m², with a rule of thumb of roughly doubling the kit cost for a total project budget.^[1][2] A cyclonic rating is reported to add 15–25% to structural cost.^[2] These are supplier-published commercial guidance, not independent survey data.

Prefabricated and modular prices are quoted in the same currency and mean entirely different things. A volumetric modular price generally buys a finished building. A panelised or kit price buys a set of components, and the labour that turns them into a house is the buyer's problem to arrange and pay for. Comparing the two figures directly is the single most common budgeting error in this part of the market. This guide sets out how package pricing is structured, what a package contains, and where the remainder of the project cost sits.

Three products, three price structures §

A builder's cost guide separates the categories usefully: volumetric modular means complete modules built in the factory and delivered to site; panelised systems means factory-made wall and floor panels assembled on site; and kit or flat-pack homes are supplied in parts for assembly by the buyer or a builder^[3]. The same source puts modular square-metre rates commonly between A$3,800 and A$4,600^[3].

That modular figure is the reference point against which package prices should be read. A kit quoted at a third of it is not a cheaper house; it is a smaller portion of the same house.

What a package actually contains §

Suppliers publish different scopes, but the pattern is consistent. A structural kit typically includes precision-cut and pre-punched wall frames, roof trusses engineered for the specific span and load, all specified fasteners and brackets, and stamped engineering documentation compliant with the National Construction Code. It typically does not include foundations, cladding, windows, plumbing, electrical work or internal fit-out^[2]. One supplier states plainly that windows and doors are excluded and sourced separately^[1].

Packages are commonly offered in tiers^[2]:

The tier is the first thing to establish about any quoted figure, because the same house can be quoted three times at three very different numbers, all correctly.

Published figures §

Supplier-published indicative prices for structure-only packages start at around A$35,000 for a one-bedroom design, A$55,000 for two bedrooms, A$75,000 for three and A$95,000 for four^[2]. Another supplier publishes a structure-only rate of A$2,600 to A$3,000 per square metre and states that frame-only packages range from around A$65,000 for compact cabins to A$200,000 or more for large family homes^[1].

All of these are commercial guidance published by companies selling the product, describing their own ranges. They are not survey data and not national averages, and because supply scopes differ they are not directly comparable with each other.

The doubling rule §

One supplier offers a rule of thumb that the total project budget is roughly twice the kit cost^[1]. Another warns from the same direction, stating that quoted kit prices exclude foundations, services, fit-out and often delivery, and that unprepared buyers face substantial overruns against their expected kit cost^[2].

Two suppliers converging on the same warning is worth taking seriously, even though neither is an independent source. The underlying arithmetic is not mysterious: a structural package removes the frame and truss component of a build, which has never been the largest share of a residential construction cost. Foundations, services, wet areas, fit-out and labour remain, and on an owner-managed project they are procured one trade at a time without a builder's buying power.

Site and exposure loadings §

Exposure requirements change the structure itself rather than being added at the end. One supplier reports that cyclonic zones — the Queensland coast and the Northern Territory — add 15 to 25 per cent to structural costs, and that a BAL-29 bushfire rating adds 10 to 15 per cent while BAL-40 or Flame Zone adds 25 to 40 per cent^[2].

These are supplier estimates rather than measured figures, but the direction is well established and matters more for packages than for turnkey products, because the buyer is exposed to the increase as a separate variation rather than absorbing it inside a fixed contract price. The underlying requirements are covered in Bushfire attack levels and prefab homes and Cyclonic and high-wind regions.

Comparing quotes that are not comparable §

Because supply tiers differ, package quotes cannot be normalised by square-metre rate alone. The workable method is the same one that applies to modular quotes: record for each line the amount, its source, its date, its GST status, who is responsible for it, and whether it is fixed or provisional, then compare the completed schedules rather than the headline figures^[4].

Two items deserve particular attention on package purchases. The first is delivery, which is frequently excluded and varies enormously with distance from the manufacturing point. The second is the boundary of responsibility: where a supplier provides components and a separate contractor erects them, the question of who is liable for a fault at that interface should be settled in writing before either contract is signed.

Documentation §

The Australian Building Codes Board's handbook sets out how evidence of suitability applies to components manufactured off site^[5]. For a package purchase this is more than paperwork: a certifier will want to see that the supplied components meet the code, and on an owner-builder project there is no head contractor whose job it is to assemble that evidence. Confirming at the point of purchase what certification travels with the package — and what the buyer must obtain separately — avoids a stall at inspection.

What is not covered here §

No independent Australian survey of completed panelised or kit project costs has been located for this guide. Every figure above is published by a company selling packages. Labour rates, which are the largest single variable in whether a kit saves money, are not covered by the sources compiled here and vary by region and by trade availability. Owner-builder permit requirements, which determine whether the buyer can legally manage the build at all, are set out in Owner-builder permits in Australia by state. Kit prices by stage and bedroom count are collected in Kit home costs.
