Prefabrication explained in detail

The practice of assembling components of a structure in a factory or other manufacturing site and then transporting the complete assemblies to the construction site for installation. Prefabricated or 'prefab' homes are becoming increasingly popular in Australia as they can reduce build times and costs.

Frequently Asked Questions

Common questions about prefabrication

Prefab or modular homes can be 10-20% cheaper than traditional builds and are typically 30-50% faster to construct. However, costs depend on design complexity, site access, and transport distances. They're particularly cost-effective for remote locations or simple designs.
