Mr. Ciar?n O'Connor:

It is very confusing because the term "modular" covers two areas. One is what is called "volumetric". In this case, the whole thing is finished in the factory and brought to site on the back of a truck. The other is where panels are made. The panels are more flexible because they can be placed in any configuration. It is a bit like a Lego kit. A wall of a given dimension can be ordered, which is then made in the factory and delivered. There is more flexibility in that. That system is used a lot in Scandinavia. In Britain, the factory method is being pushed because a greater output can be achieved in a shorter time. That is what is driving that. The skills base for that is different from the skills base needed on-site. In Scandinavia, the people who put the modular houses together in the factories are mainly women whereas those on the sites are predominantly men.
