Thank you very much, Deputy Presiding Officer. Can I thank UKIP for bringing this debate forward? I think it's actually a very important subject and is a way of tackling the housing challenge in Wales. I hope that we develop a level of consensus beyond our usual, conventional, traditional house building methods.

I was very pleased, actually, to notice that even the Welsh Government seems to be moving a bit in this area. In the statement in October that introduced the innovative housing programme, one element that was included was modular housing. So, I think we are pushing at an open door, to use an appropriate colloquialism. 

In my response to that statement, I did speak about how I hoped the Welsh Government would undertake more modular house building. I'm pleased to see that UKIP have picked up on this also and share a vision for its greater use, particularly in some of the changing circumstances and the urban communities that we're now seeing develop, partly in response to the new type of housing that we do require.

As has already been alluded to—. Overall, I wanted to be as constructive as possible with the motion, so I've just amended it where we absolutely do have a slight issue, and that's the proposal for a housing corporation, aiming to bring in much more brownfield land. I completely share the objective, but I think this is a rather bureaucratic way of going about it and I think there are plenty of levers for Government to do this and they need to get on and achieve better results, I think, in terms of land supply. And it's not just brownfield sites, but they are an important source.

We need to build on—. Obviously, we need to release more land if we're going to see more house building. It really is important that we look around and are creative and look at the public sector. Lots of land is fairly redundant or could be used more innovatively and more economically, therefore releasing land for development. So, that was the reason we amended the motion.

As David said, modular housing, or what we used to call prefabs, has a very noble record. It was a central part of solving the crisis of post-war house building. The challenge they faced was just beyond anything the nation had experienced before because of the destruction in the second world war. Vast numbers, which David outlined, were built. I think that, when we look at the opportunities today, we should reflect on the role it had then. Many of the housing units that were built were innovative for the time, and they were popular—a point David made. I remember campaigning, against Jane Hutt I should say, in a whole street of prefabs that still survived in Barry, and the residents were very happy with that way of living. It was really quite a convenient layout. I was shown around. I'm not sure the person voted for me, but there we are. [Laughter.] I was never successful in either election I fought there. But it does show you that these methods can be absolutely sector-leading, and today even more so in terms of speed of construction and cost—about twice as quick and half as expensive. There are a lot of innovations as well—new materials, less energy-dependent and they can also lead to this incredible SOLCER experiment, where you actually generate energy from the house rather than consuming it. So, there are a lot of opportunities there.

I think it also allows us to look at the possibility of higher density developments—not high-rise—where there are more shared facilities, for instance. Not everyone wants a garden to maintain. I've often said to people when you go to posh areas in London, like Belgravia, they all have a key for the central garden; they don't have their own garden. It's regarded as a great social advantage to have access to those gardens. So, there are ways of building family-sized homes very efficiently and possibly, potentially, eliminating fuel poverty because you'd actually be getting money back from your home.

Can I just say in conclusion, Deputy Presiding Officer, that SMEs are very well placed to take advantage in this sector? Also, the shortfall we have in some building skills would be addressed more quickly in this sector. There are a lot of opportunities there. I do think they've been unloved for too long, and we should see that it's time for a renaissance in modular building. Again, I thank UKIP.
