In the late 1950s, greater than a decade following the war instead of long after the rock and roll explosion, Britain embarked on the house-building programme the like which we have now never seen before or since.
There is suddenly a need for more than a quarter of your million new homes every year as new towns were manufactured to replace the previous slums and families sought more space to accommodate the child boom. In order to meet this, large numbers of houses were integrated factories after which assembled on location.
These prefab house came into existence as closely linked to the next several years as Billy Bremner or maybe the Beatles. In reality, it was actually something of any exaggeration, because they never comprised greater than 15% of new builds in an era the location where the high rises were a bigger game changer.
During the early 1970s, prefabs suddenly went out of style, rich in rises not far behind. The need for such speedy building had reduced. Insurance carriers had begun refusing to insure them since it became clear there were a lot of troubles with the building techniques they would not last nearly given that 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 building a comeback – though these days it will always be generally known as off-site construction. When the momentum keeps increasing, it will almost certainly go to dominate house building over the UK and possibly elsewhere in ways that 06dexspky happened in the 1950s and 1960s.
Scotland continues to be at the forefront. Partly this is certainly thanks to timber frame housing, which is far more extensive north of your border. Timber frames became popular in Aberdeenshire from the 1980s to satisfy the nascent oil and gas industry, then gradually spread to other elements of Scotland.
Through the early 2000s, framing companies began merging with many other players like insulators and gradually took benefit of their new strength thorough to move into building kit houses offsite. With the pre-recession peak of 2007, off-site new build had grown from under 10% of most new Scottish houses to between 25% and 30%.
By that year, the total quantity of new houses being built in the UK was around 200,000. This fell to simply over 110,000 as demand collapsed. After a couple of lean years it is on the up again (see image), fuelled by the UK Government’s Assist to Buy scheme.
But the majority experts agree it is going to have to increase far more quickly if we are going to satisfy demand in the future. The United Kingdom Government estimates that we must build 260,000 houses every year in England and Wales between 2015 and 2031 and 35,000 annually in Scotland.

Not simply are these targets way ahead of what we should were building even in the pre-recession peak, there are numerous other pressures on construction:
replacing skilled workers who may have left the business sector through 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 using their company sectors such as oil and gas and major infrastructure works for rail, road and power stations.
When building reduces
Lots of people believe that offsite is the answer. As outlined by case studies by Build Offsite, the sector body, the savings feature a 10% to 15% decrease in the expense of building; along with a 40% decline in vehicle movements.
It may also help with builders’ mounting energy performance requirements. House building is put beneath the microscope lately to figure out where improvements can be produced – as an example one recent research area has been improving buildings’ external insulated fabric.
Off-site manufacturing assists with this since it gives builders additional control over each stage of the construction process. Furthermore, it means you can reduce waste and also have better control of the kinds of waste being generated, while implementing techniques favored by other sectors such as just-in-time delivery.
To employ this potential, steel structure warehouse like Kingspan, CCG and Stewart Milne have been investing heavily in facilities during the recession years.
Inspired from the lean construction models of auto producers like Ford and Toyota, plants 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 many other materials; while in Scotland it really is now 50 plusPer cent.

By using the likes for the future Construction Scotland Innovation Centre, that can bring together academics and researchers from 11 universities, these manufacturers are developing increasingly advanced assembly techniques which will include smart technology, intelligent membranes and even nanotech. To mirror these technologies and systems some believe the the off-site sector may change its name to Advanced Construction.
The proportion of off-site construction will simply keep growing. Chances are that by 2017, over 70% of the latest Scottish homes will be built in this manner, while the rest of the UK will demonstrate exactly the same upward momentum. Several of the prefabricated homes may also be attracting interest from China, Europe, Brazil and Russia, where this segment has yet to consider off.
Having got off-site construction so wrong at the first try around, this time promises to be really different. Do your building industry a favour: don’t call it prefab.
