Prefabricated Housing

Debate between Damian Collins and Roberta Blackman-Woods

Wednesday 4th November 2015 Westminster Hall

[Dr Roberta Blackman-Woods (City of Durham) (Lab)]

May I say what a pleasure it is to serve under your chairmanship, Mr Owen? I congratulate the hon. Member for Folkestone and Hythe (Damian Collins) on introducing an interesting element to our housing debate.

This week we have rehearsed the point well that we are in the middle of a housing crisis. Last year’s output was only 117,000 homes, and we need about 245,000 a year, so anything that can help us to plug that huge gap in supply has to be looked at carefully, especially given the number of homes we are producing for social rent: we produced fewer than 11,000 last year—nowhere near enough. We should be delivering about 78,000 each year if we are to meet need. We should therefore look in some detail at providing what the hon. Gentleman rightly described as off-site housing, rather than prefab housing.

This is not an easy debate. The hon. Gentleman said that we do not come to this issue in a vacuum, because a number of us have experienced prefab housing built between the wars, and during and after the second world war—housing that had to be demolished in the 1970s and rebuilt. Results varied across the country. Some prefab estates lasted much longer than that, and many people who live in them really like them, but many of those houses were of insufficient quality to last and had to be demolished. We need to be careful to say that we are not talking about that sort of housing.

The Government’s off-site housing review report, commissioned in 2013, suggested that prefabricated construction methods could form part of the solution to England’s housing supply crisis. It would be helpful to hear from the Minister what the Government are doing about that report, and whether they plan to incentivise the building of that housing in any way.

The report highlighted examples such as Y:Cube, a prefabricated home scheme developed by the YMCA in London that boasts self-contained, one-bedroom flats with their own bathroom, living room and kitchen—all in a compact unit of 26 square metres. Those homes are for vulnerable young people, and it is encouraging that they meet code level 6 energy requirements. A three-week test showed that each home could be lit and heated to 20° C all day and all night for £7 a week. That is really good in terms of energy costs, and the home has a lifespan of 60 years or more.

[Damian Collins]

That scheme, which was designed for vulnerable people, is very exciting. It also makes it possible for someone who lives in a house in multiple occupation to think about having a home of their own.

[Dr Blackman-Woods]

I absolutely agree. The task is to try to envisage a wider role for such specialist housing. I think that we can see that, but there is a real issue about how we can spread it more widely. I want to raise a couple of issues that need to be taken on board if it is to have much wider application.

Although the units in that scheme in south-west London had high energy efficiency and insulation specifications, that is not always the case. Some off-site housing still has poor insulation, or uses insulation materials that will not stand the test of time. That must be taken on board.

Points were made about off-site construction using less raw material. That might be the case in construction, because when houses are built in a factory to the same design, companies will create less waste. However, in transporting these units, a lot of wood and plastic is often used; those issues need to be taken on board.

[Dr Blackman-Woods]

I am listing things that need to be taken into consideration. It is as if we had a balance sheet and needed to see the evidence. That is the point—we need evidence, and we need to make sure that these issues are addressed. The hon. Member for Folkestone and Hythe said that he wanted a revolution. I am not suggesting for a minute that there is no role for this sort of construction, but before it becomes more widespread throughout the country and across different types of housing—before the revolution—we need to be sure that we are not building up problems with transport, or with more movement on and off site. We also need to ensure that people have the right skills to construct the units properly.

[Damian Collins]

One attractive thing about the schemes is that not only can we use a factory at a distance from the site, but pop-up factories can be built on site, to create the units where they will be deployed.
