How this system works
Concrete panels or other elements are manufactured off-site to the dimensions of the design. They are then transported and assembled on prepared foundations. Connections between pieces and to the base are part of the engineering and construction.
Prefabricating the structure does not automatically deliver a finished house. Some quotes cover panels only; others add roof, windows, services and finishes. Scope should be written down before comparing prices.
How it is built, step by step
- Finalise design, dimensions and connection points before manufacturing pieces.
- Prepare foundations, access, unloading space and lifting equipment.
- Transport and assemble elements following the connection design.
- Complete joints, insulation, roof, services and contracted finishes.
Advantages
- Factory manufacturing enables components and quality checks to be planned before assembly.
- Some work takes place off-site and assembly can reduce on-site tasks.
- Concrete elements offer different structural and finish options depending on the system.
Drawbacks and how to address them
- Transport and cranes require access and space; a difficult plot may constrain the solution.
- Changing dimensions after manufacturing may require changes to pieces and the quote.
- Fast assembly is not the total house delivery time: preparation, manufacturing and finishing still count.
When it might suit you
It can be worthwhile if the design is finalised, the plot allows assembly and the quote clearly separates manufacturing, transport and the finished house.
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.
