A recent announcement by government has caused quite a stir. The suggestion is that we might build a new generation of ‘prefabs’ to help solve the housing crisis. A reasonable suggestion, after all it has the potential to cut through materials shortages, domination by volume house builders and provide houses more quickly and efficiently. The problem seems to be with the word ‘prefab’ as this evokes memories of the post-war building that took place, providing quick, cheap homes that were only ever meant to be temporary, but ended up housing people for decades in what later became unfit homes.
So what is a modern day ‘prefab’ and why would we even contemplate it now? Prefabs are now more commonly called factory built, modular homes or kit houses. The idea of ‘kit housing’ has been around for some time and indeed is pretty standard in France and Germany where volume house builders do not rule the market. The beauty of kit housing is that it is factory built, it’s cheaper and can be erected on site pretty quickly. There are many companies out there providing this form of housing, from the original and more expensive Huf Haus, to relative newcomers to the arena like Apple Green Homes, and Snug Homes.
The government is now proposing to use some of the £3bn house building fund to support small and medium sized builders to provide a new generation of prefabs. The advantage this type of building has is that it is generally constructed off site, in a factory building, so less constrained by weather. It uses different materials so is not subject to the same shortages and problems associated with traditional brick built dwellings and is often cheaper. Indeed many of the new model of prefabs are developed as small units, that are affordable, but which can be connected to form larger units. They also tend to be built to high environmental standards, with many of the designs modelled on Scandinavian, Dutch and German models, where energy efficiency and sustainability are central to the design approach.
At the moment we are not geared up to this type of development in the same way as many other European countries are, it’s not been a significant part of our housing model for over 60 years. But there are plenty of examples we can look at to see how it works, at a reasonable scale, as a core part of housing delivery. In Nijmegen, The Netherlands, where I worked for a while, they are now proposing to provide sites for people to build flat-packed affordable homes under a new initiative called ‘Ik bouw betaalbaar in Nijmegen’ (IbbN). These can be constructed on site within a few weeks. In Almere, near Amsterdam, the municipality set aside 100 hectares, with the aim of creating the opportunity for around 3,000 self build homes across the overall development, many of which are timber framed, modular builds.
But could we do it here, to a big enough scale to make an impact – that’s the key question. With support from government and local councils, land provision and support from mortgage lenders, it’s possible. These should not be seen as temporary, low cost solutions, but as permanent, affordable solutions. It will be important to ensure the highest of environmental standards and quality are a core part of the approach, as they are elsewhere. It will be interesting to see what the White Paper, due out later this month, actually says in terms of funds and support. One thing we definitely need to do is get beyond the outdated perception we have of ‘prefabs’ and start to see the possibilities that modular homes can provide to help us solve the housing crisis.
