How this system works
A modular house is organised into units manufactured off-site. Modules may arrive with different levels of finish and use timber, steel, concrete or other materials. Modular describes manufacturing and assembly, not one material.
Modules are placed on a prepared base and connected to each other and to services. A hybrid system combines materials or processes: clarify what is manufactured, what is built on-site and who coordinates the whole.
How it is built, step by step
- Define layout, module dimensions and the extent of factory finishes.
- Check transport, access, crane, foundations and utility connections.
- Manufacture units and prepare the plot during the agreed phases.
- Assemble, connect, finish junctions and complete final checks.
Advantages
- Part of the home is prepared off-site and may arrive with finishes already incorporated.
- Manufacturing and ground preparation can be planned as coordinated phases.
- There are solutions with different materials and levels of customisation.
Drawbacks and how to address them
- Module dimensions and transport may limit some plots or access routes.
- Late changes to layout or finishes may affect manufacturing and cost.
- Check exclusions: foundations, transport, utility connections and finishing are not always included.
When it might suit you
It may suit you if you accept a design and scope defined before manufacturing and the plot logistics are resolved.
What the quote should include
Compare the same scope and performance. The structural material alone does not determine which offer is better.
- Design, ground assessment and foundations.
- Structure, roof and complete facade build-up.
- Insulation, windows and solutions for water, noise and fire.
- Services, finishes, transport and assembly where applicable.
- Schedule, taxes, exclusions and responsibility for each phase.
