Are modular homes cheaper than traditional homes?

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

Not automatically. Published guidance puts modular homes at about A$3,800–A$4,600 per m², with small homes from about A$300,000, and site works, transport, crane hire and connections are quoted separately.^[1][2] Published timelines are shorter: factory manufacturing windows of about 8–14 weeks, and a module-side critical path of roughly 4–6 months against 9–14 months for comparable traditional construction.^[3] These are builder-published commercial guidance, not independent survey data.

What the published figures show §

Australian builders publish modular rates of roughly A$3,800 to A$4,600 per m², with some advertising from about A$2,300 per m².^[2] Base prices are commonly quoted from about A$300,000 for a small home, A$500,000 for a family-sized one, and A$700,000 to over A$1 million for large or bespoke designs.^[1]

Those figures sit within the range of conventional construction rather than dramatically below it. Anyone expecting off-site building to halve the cost of a house is likely to be disappointed.

Why the comparison is difficult §

A modular base price describes the factory-built structure. Site works, transport, crane hire and service connections are quoted separately and are highly site-specific.^[2] A traditional builder's quote usually bundles more of that work into a single figure.

So comparing a modular base price against a traditional turnkey price compares two different scopes. The comparison only becomes meaningful when both are itemised to the same list.

Where the real advantage sits §

The stronger case for off-site construction is cost certainty rather than lower cost. A factory contract prices a defined product built under controlled conditions, so weather and trade availability affect it far less than they affect an open site.

Time is the related advantage. Published guidance puts factory manufacturing at roughly 8 to 14 weeks with a module-side critical path of about four to six months for projects up to 30 modules, against nine to fourteen months for comparable traditional construction.^[3] Time saved is interest saved and rent saved, which is a real financial benefit even when the build price is similar.

Where modular does tend to win on price §

• Remote and rural blocks, where conventional building requires trades to travel repeatedly over months.
• Repeatable dwelling types such as secondary dwellings, where factory efficiency has something to work with.
• Projects where delay is expensive — rent, interest, or a fixed occupancy date.

Where it does not §

• Complex bespoke designs that fight the module dimensions.
• Sites where crane access is difficult, since delivery-day costs can reach roughly A$23,000 to A$30,600 on remote or complex lifts.^[2]
• Blocks far from the factory, where transport charges apply beyond an included radius.^[2]
