Within the late 1950s, over a decade once the war and not long after the rock and roll explosion, Britain embarked on a house-building programme the like in which we now have never seen before or since.
There is suddenly a requirement for over a quarter of your million new homes each and every year as new towns were designed to replace the old slums and families sought extra room to allow for the infant boom. To satisfy this, many houses were integrated factories after which assembled on location.
These prefab house came to be as closely related to the next several years as Billy Bremner or even the Beatles. In fact, this became actually something of an exaggeration, because they never comprised over 15% of the latest builds in an era where high rises were a much bigger game changer.
In early 1970s, prefabs suddenly went out from style, with higher rises not far behind. The need for such speedy building had reduced. Insurance firms had begun refusing to insure them mainly because it became clear that there were a lot of troubles with the building techniques which they would not last nearly so long as people had hoped. Suddenly new homes comprised blocks and bricks and were between two and four storeys in height.
Yet whisper it, pre-fabrication is making a comeback – though these days it usually is called off-site construction. In the event the momentum keeps increasing, it will probably visit dominate house building across the UK and maybe elsewhere in a way that 06dexspky happened from the 1950s and 1960s.
Scotland has become leading the way. Partly this really is because of timber frame housing, which is more extensive north in the border. Timber frames became popular in Aberdeenshire from the 1980s to fulfill the nascent oil and gas industry, and after that gradually spread for some other aspects of Scotland.
Through the early 2000s, framing companies began merging with some other players for example insulators and gradually took benefit from their new strength in depth to go into building kit houses offsite. From the pre-recession peak of 2007, off-site new build had grown from under 10% of all the new Scottish houses to between 25% and 30%.
By that year, the total variety of new houses being built in britain was around 200,000. That fell to just over 110,000 as demand collapsed. After a couple of lean years it can be in the up again (see image), fuelled through the UK Government’s Assist to Buy scheme.
But the majority experts agree it will have to increase considerably more quickly if we will satisfy demand for the future. Great Britain Government estimates we will need to build 260,000 houses each year in England and Wales between 2015 and 2031 and 35,000 each and every year in Scotland.

Not only are these targets way ahead of what we should were building even through the pre-recession peak, there are several other pressures on construction:
replacing skilled workers who definitely have left the marketplace sector throughout the recession and therefore are not returning;
high average age in a few lines of labor, meaning increasing retirement rates;
a lot of refurbishment to existing housing stock;
delays to utility connections on work sites;
pressure on prices and workers from demand off their sectors including oil and gas and major infrastructure works best for rail, road and power stations.
When building fails
Lots of people feel that offsite is the answer. As outlined by case studies by Build Offsite, the sector body, the savings incorporate a 10% to 15% decline in the expense of building; along with a 40% decrease in vehicle movements.
It may also help with builders’ mounting energy performance requirements. House building has been put within the microscope in recent years to determine where improvements can be created – for example one recent research area continues to be improving buildings’ external insulated fabric.
Off-site manufacturing is great for this mainly because it gives builders more control over each stage of your construction process. Furthermore, it means it is possible to reduce waste and also have better control of the types of waste being generated, while implementing techniques popular with other sectors including just-in-time delivery.
To utilize this potential, steel structure warehouse for example Kingspan, CCG and Stewart Milne have already been investing heavily in facilities during the recession years.
Inspired from the lean construction kinds of auto producers for example Ford and Toyota, plants have emerged or expanded in places like Glasgow, Manchester, Aberdeen, Derby and Motherwell. Off-site now comprises between 15% and 20% of house building in England and Wales, having moved beyond timber frames to varied other materials; during Scotland it really is now over 50Percent.

Through the help of the likes for the future Construction Scotland Innovation Centre, which brings together academics and researchers from 11 universities, these manufacturers are developing increasingly advanced assembly techniques that may include smart technology, intelligent membranes and in many cases nanotech. To reflect these technologies and systems some believe the the off-site sector may change its name to Advanced Construction.
The proportion of off-site construction is only going to keep growing. It is likely that by 2017, greater than 70% of the latest Scottish homes will likely be built by doing this, while the other UK shows the identical upward momentum. A few of the prefab homes can also be attracting interest from China, Europe, Brazil and Russia, where this segment has yet to take off.
Having got off-site construction so wrong the very first time around, this period promises to be really different. Simply do the construction industry a favour: don’t call it prefab.
