Prefabricated Housing

Debate between Damian Collins and Alan Brown

Wednesday 4th November 2015 Westminster Hall

[Alan Brown (Kilmarnock and Loudoun) (SNP)]

It is a pleasure, Mr Owen, to serve under your chairmanship for the first time in a Westminster Hall debate.

I thank the hon. Member for Folkestone and Hythe (Damian Collins) for securing the debate. I agreed with a lot of what he said, so there is a risk that he will think that I have cribbed his speech. The debate is timely given that earlier in the week we had Second Reading of the Housing and Planning Bill in the House. We discussed the right to buy in social housing, which I spoke against for various reasons. One thing that was agreed, however, given the right to buy, was the need for replacement housing to be put back into circulation. Obviously, as has been said, prefabricated housing or off-site construction is one way to speed up that process cost-effectively.

As the hon. Gentleman said, the term “prefabricated housing” takes us back to the image of post-war housing. Although those prefabricated houses are now somewhat maligned, I agree that we have to compliment the ingenuity of the time. The houses served a real need, providing housing on site quickly when there was a shortage of raw materials. Also, the people who stayed in those prefabricated homes in general loved living in them, and some remain today, which is a testament to how well the houses were built, although in energy efficiency they no longer serve modern purposes. When I was a councillor with responsibility for housing, adapting that older prefabricated housing to energy-efficient standards was a real challenge, if not impossible. It is therefore good to revisit the prefabricated home with modern technologies for the new house build.

Over the years in Scotland, especially in the private housing sector, there has been a switch to kit houses, with much of the frame built off site for quick assembly on site, speeding up the whole building process. It makes sense that off-site construction has evolved further to provide complete wall panels, which come with insulation or even services included, and modular units.

In off-site construction, “modular units” is a more popular term than “prefabricated houses”, because it does not have quite the same connotation in the imagination. Modular units are now used for schools and offices, and we have heard about a retail development. No one looks at those units and thinks, “Oh, they were prefabricated”, or, “That’s off-site construction; it will only have a 10-year lifespan.” They look and feel permanent and have similar lifespans to traditional builds. It makes sense for modular units to be extended into the housing sector.

[Damian Collins]

The delivery of the London Olympic games was a triumph for UK design and architecture in many ways, and a prefabricated or off-site constructed unit was used for the basketball arena. It was a temporary building that was constructed for the games, but could then be disassembled and relocated to other places around the country.

[Alan Brown]

The hon. Gentleman makes a fair point about the successful delivery of the 2012 Olympics and prefabrication helping to control budgets.

It might surprise the House to know that Scotland is ahead of the curve with off-site construction and prefabrication. In 2013 there was an estimated construction value of £125 million in Scotland, compared with only £46 million in the rest of the UK. That illustrates a stark difference. Also in 2013, it was estimated that 50% of new houses in Scotland had an off-site build element, which again is a much higher rate than in the rest of the UK. We also have a much higher new build rate in social housing and private housing, and the 50% rate clearly contributes to that. Scotland’s housing growth also means a potential increase in exports, creating new jobs and keeping traditional construction jobs on site. There has been a real fillip for the construction industry.

I agree that there is less waste on site when there is off-site construction, and vehicle movements to and from the site can be reduced by up to 40%. We should consider that housing developments often take place adjacent to existing houses, so that reduction in movements is great for reducing disruption to local residents. Of course, having fewer vehicles also brings a safety benefit.

[Damian Collins]

Does the hon. Gentleman agree—I would also welcome the Minister’s thoughts on this—that we could consider off-site construction and assembly as having an advantage in the planning system, because there is less disruption to residents during the construction phase than with a normal build?
