What does the jingle–jangle fallacy have to do with building homes?
More than you might think.
The jingle fallacy occurs when we assume different things are the same because they share the same name.
Take the word modular.
• A flat-pack building kit can be called modular.
• A panelised system can be called modular.
• A transportable building can be called modular.
• A module constructed using traditional building methods can be called modular.
• And a precision-manufactured volumetric home can be called modular.
Same label. Very different products and processes.
That is the modular jingle.
The reverse also happens. Similar systems may be described as volumetric construction, off-site manufacturing, industrialised construction or modular manufacturing.
Different names can make similar things appear unrelated.
That is the jangle.
Why does this matter?
Because imprecise terminology creates:
• false price comparisons
• misleading assumptions about build times
• confusion about what is completed in the factory
• uncertainty about how much work remains on site
• poorly defined procurement requirements
• a failure to recognise genuine manufacturing innovation
Fortro creates precision-manufactured volumetric homes.
Each home is produced as a series of precision-manufactured volumetric modules. These modules are complete, steel-framed, three-dimensional building sections manufactured through an integrated production system.
Fortro’s process combines precision machinery, automation, synchronised assembly-line production, digital workflows and real-time tracking. The completed volumetric modules are transported to site, craned into position and connected to form the home.
The distinction is simple:
Flat-pack systems deliver building parts to be assembled. Fortro delivers complete building volumes to be connected.
All Fortro precision-manufactured volumetric homes are modular.
But not everything described as modular is volumetric—and not every volumetric home is precision-manufactured.
Perhaps the industry needs to stop asking:
“Is it modular?”
And start asking:
“What leaves the factory, how was it produced and what still needs to happen on site?”
