Almost every prefab supplier in South Africa will tell you their product is cheaper than building. We sell prefab homes, and we think that answer is too simple to be useful — it depends entirely on what you put on the other side of the comparison, and there are cases where conventional building genuinely wins.
So here are our own numbers, per square metre, against what a conventional build costs. Every figure in the first column comes off the same price list the product pages use.
What a conventional build costs per square metre
There is no single national number, and anyone who gives you one is rounding hard. Industry cost guides for 2026 put a mid-range conventional home somewhere in the region of R10 000 to R15 000 per square metre, with budget builds below that and luxury finishes well above. It varies by province, by finish level, and by how much of the site work is already done.
Two things to hold on to about that number. It is a construction rate — it does not include the land, and it frequently excludes professional fees, municipal connections and site works. And it is an average of an enormous range: the same 40 m² in the same suburb can differ by a factor of two depending on the specification.
What our units cost per square metre
| Unit | Floor area | Price ex VAT | Per m² | What that buys |
|---|---|---|---|---|
| X-Fold | 15 m² | R 54 900 | R 3 660 | Insulated shell, electrics only, no plumbing |
| Expandable 18 m² | 18 m² | R 199 900 | R 11 110 | Self-contained: bathroom, basic kitchen, services in |
| Expandable 37 m² | 37 m² | R 329 900 | R 8 920 | 2 bedrooms, fitted bathroom, full kitchen |
| Expandable 74 m² | 74 m² | R 599 900 | R 8 110 | Up to 4 bedrooms, fitted throughout |
| Apple Cabin | 13 m² | R 449 900 | R 34 610 | Panoramic glass, luxury bathroom fittings |
| Nature Cabin | 26 m² | R 810 900 | R 38 610 | Fully fitted incl. kitchen, aircon, water heater |
| Glamping Capsule | 18.6 m² | R 689 900 | R 37 090 | 270° glazing, premium bathroom, geyser |
Read that table honestly and it does not say "prefab is cheaper". It says three different things.
The shell is dramatically cheaper — because it is a shell
At R 3 660 per square metre the X-Fold is a fraction of any conventional rate. It is also a room with two plug points, a light and no plumbing. Compare it to building a bare insulated room, not to building a house, and the comparison is fair. Compare it to a granny flat and it is not.
The mid-range lands inside the conventional band
The expandable homes run from R 11 110 down to R 8 110 per square metre as the size goes up — squarely inside the R10 000–R15 000 band a conventional mid-range build is quoted at. On a per-square-metre basis this is roughly a wash.
Where it stops being a wash is what is inside the number. That rate already includes 75 mm EPS insulated walls, vinyl flooring, double glazing, a fitted bathroom and factory-installed plumbing and electrics. A conventional R/m² construction rate is frequently quoted before some of those. Compare like with like and the expandable is usually ahead — but not by the multiple the marketing in this industry implies.
The premium units cost more per square metre, and should
An Apple Cabin at R 34 610 per square metre or a glamping capsule at R 37 090 is well above any conventional residential rate. That is not a prefab premium; it is a finish premium. You are buying floor-to-ceiling panoramic glazing, premium bathroom fittings and a unit built to be photographed and let out at a nightly rate. Building that conventionally would not be cheaper — it would be considerably more, and it would take a year.
Where prefab wins, and it is not mainly price
- Time. Around 90 days from deposit to move-in, with on-site setup running from minutes for an X-Fold to a few days for a cabin. A conventional build of the same size is a multi-month programme on your property.
- Price certainty. You are quoted a figure for a finished unit. Conventional building is quoted on a rate and a scope, and the final number is the one nobody can tell you at the start.
- Disruption. The building work happens somewhere else. There is no site, no rubble, no trades in your garden for months.
- Relocatability. An X-Fold folds down; a pod lifts out. A brick room stays with the property whatever happens next.
Where conventional building wins
- You want a specific layout. Prefab is catalogue-shaped. If the space has to fit an awkward site or an exact brief, conventional building does that and a factory unit does not.
- You are already building. If contractors are on site for a larger project, adding a room to that scope is often cheaper than a separate delivered unit with its own transport and groundwork.
- You need bond finance. More banks will lend against conventional construction than against a prefab structure — this is the single most underrated cost difference, and we have written it up separately in can you get a home loan for a prefab home.
- Access is impossible. If a truck and crane cannot reach the spot, the delivered-unit model does not work at any price.
The comparison that actually decides it
Compare delivered, standing, connected and usable — not sticker against rate. For a prefab that means the unit plus transport, groundwork and service connections. For a conventional build it means construction plus fees, connections and the contingency you will use. Both numbers are larger than the one first quoted, and they are the only two that can honestly sit next to each other.
Then weigh the things that are not money: how long you are prepared to live with a building site, and how much you value knowing the final figure up front.

Price a unitQuick answers
No. Per square metre our expandable homes land inside the same band as a mid-range conventional build, our premium cabins and capsules sit well above it, and only the bare X-Fold shell is dramatically below. What prefab reliably beats is the timeline and the price certainty, not always the total.
