Mr. Cormac O'Rourke:

There is no doubt but that capacity constraints exist within the industry and that it is having an impact on delivery. As I outlined in my statement, one of the ways of perhaps adding to the capacity of the industry is to go to modular building but that is not going to happen overnight. The advantage of timber-frame housing and timber-frames for duplexes and other structures is not only does that add capacity, but it is also a much more sustainable and faster form of building. Timber-frame houses are watertight within a few weeks, and it is possible then to work inside and outside simultaneously. That is going to be a factor, but it is going to take us time and it will require engagement with the industry before we can operationalise it. I will pass over to Mr. Coleman on the question of staffing, because he knows the answer to this much better than I do.
