	The reality is that you are just changing the process – the building materials, such as the structural steel frame, remain the same as a site-based solution but construction takes place off site in a more controlled factory environment. This means better quality because the process is not subject to poor weather – which can cause serious quality issues post-completion, as well as a greater risk of delays and budget overruns.
