Within the late 1950s, greater than a decade once the war and not a long time after the rock and roll explosion, Britain embarked with a house-building programme the like of which we certainly have never seen before or since.
There was suddenly a necessity for more than a quarter of a million new homes each and every year as new towns were manufactured to replace the previous slums and families sought more space to allow for the baby boom. To meet this, large numbers of houses were integrated factories after which assembled on location.
These prefab house came to be as closely related to the next number of years as Billy Bremner or the Beatles. In reality, this was actually something of your exaggeration, because they never comprised a lot more than 15% newest builds in an era where the high rises were a much bigger game changer.
During the early 1970s, prefabs suddenly went out of style, with good rises not far behind. The requirement for such speedy building had reduced. Insurance providers had begun refusing to insure them because it became clear there were a lot of problems with the building techniques they would not last nearly as 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 nowadays it is always referred to as off-site construction. In the event the momentum keeps increasing, it will probably go to dominate house building throughout the UK as well as elsewhere in ways that 06dexspky happened inside the 1950s and 1960s.
Scotland is leading the way. Partly this really is because of timber frame housing, which is a lot more extensive north from the border. Timber frames became popular in Aberdeenshire inside the 1980s to fulfill the nascent oil and gas industry, and then gradually spread to many other areas of Scotland.
Through the early 2000s, framing companies began merging with other players for example insulators and gradually took benefit of their new strength detailed to advance into building kit houses offsite. With the pre-recession peak of 2007, off-site new build had grown from under 10% of all new Scottish houses to between 25% and 30%.
By that year, the total number of new houses being built in the united kingdom was around 200,000. Then it fell to simply over 110,000 as demand collapsed. After a few lean years it is on the up again (see image), fuelled from the UK Government’s Aid to Buy scheme.
But the majority experts agree it is going to have to cultivate a lot more quickly if we are going to satisfy demand in the future. Great Britain Government estimates which we will have 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 before whatever we were building even throughout the pre-recession peak, there are numerous other pressures on construction:
replacing skilled workers who definitely have left the industry sector throughout the recession and so are not returning;
high average age in some lines of work, 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 like oil and gas and major infrastructure works for rail, road and power stations.
When building fails
Lots of people think that offsite is the answer. According to case studies by Build Offsite, the sector body, the savings incorporate a 10% to 15% decrease in the fee for building; as well as a 40% decline in vehicle movements.
It may also help with builders’ mounting energy performance requirements. House building has become put underneath the microscope in recent years to understand where improvements can be produced – for example one recent research area continues to be improving buildings’ external insulated fabric.
Off-site manufacturing helps with this since it gives builders additional control over each stage of your construction process. In addition, it means you may reduce waste and get better control of the types of waste being generated, while implementing techniques well-liked by other sectors such as just-in-time delivery.
To utilize this potential, steel warehouse including Kingspan, CCG and Stewart Milne are already investing heavily in facilities during the recession years.
Inspired by the lean construction models of car manufacturers like 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 various many other materials; while in Scotland it is actually now 50 plusPercent.

By using the likes of the future Construction Scotland Innovation Centre, which brings together academics and researchers from 11 universities, these manufacturers are developing increasingly advanced assembly techniques that will include smart technology, intelligent membranes and also 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, more than 70% of new Scottish homes will probably be built this way, while the remainder of the UK will demonstrate a similar upward momentum. Several of the prefab homes are also attracting interest from China, Europe, Brazil and Russia, where this segment has yet for taking off.
Having got off-site construction so wrong at the first try around, this time promises to be very different. Just do the property industry a favour: don’t consider it prefab.
