Prefabricated is the umbrella
A prefabricated building may be volumetric modular, panelised, framed as a kitset, or use a hybrid of those methods. The label alone does not define freight, completion level or site work.
Decision Centre / Global
Prefab, modular or kitset building?
These terms overlap, so the first job is to define how much of the building is completed before it reaches site. Prefabrication is the broad category; modular and kitset or panelised systems are different delivery methods within it.

Direct answer
The short version.
Choose volumetric modular construction when factory-completed room modules and rapid site assembly suit the transport route. Choose kitset or panelised delivery when compact freight, flexible building size and more destination assembly are acceptable. Use 'prefab' as the umbrella term, then specify which manufacturing and delivery method the project actually needs.
Project decision
What matters before product selection.
Use these points to structure the first project conversation. Final suitability stays tied to the actual site, selected system and local project team.
Volumetric modular
Three-dimensional modules can arrive with more internal work completed, reducing destination assembly but increasing transport dimensions, lifting requirements and module-joint coordination.
Kitset / panelised
Frames, panels and components pack more densely for shipping and allow larger final buildings, but shift more erection, weatherproofing, services and finishing work to the destination.
Comparison matrix
Prefab vs modular vs kitset
Compare the delivery method against freight, local labour, site access and the final building brief.
| Factor | Volumetric modular | Kitset / panelised |
|---|---|---|
| Factory completion | Higher potential | Lower to moderate |
| Transport volume | Higher | More compact |
| Crane / lifting | Often significant | Project dependent |
| Site assembly | Faster module placement | More erection and envelope work |
| Design flexibility | Module dimensions influence planning | Greater freedom within structural system |
| Remote / island logistics | Works where module transport is practical | Often attractive for containerised freight |
| Services | Can be partly pre-integrated | More destination coordination |

Frequently asked
Answers without oversimplifying the project.
Is one option always the right choice?
No. The useful choice depends on the project outcome, site conditions, scale, local work, operating expectations, maintenance and the technical evidence available for the exact system.
Does Apollo calculate a universal online price from this guide?
No. Apollo uses a project-brief and quotation process so product family, configuration, quantity, destination, freight and project interfaces are reviewed before pricing.
Who handles local engineering, approvals and installation?
Apollo is primarily supply-only. Local engineering, approvals, foundations, services, installation and other site work remain with the appointed local project team unless a written scope states otherwise.
Next step
Turn the research into a real project brief.
Send the site, dimensions, intended use, quantities and known local requirements. Apollo will review the relevant product pathway and keep local engineering, approvals and site-work responsibilities explicit.
