In the late 1950s, more than a decade once the war and never a long time after the rock and roll explosion, Britain embarked over a house-building programme the like which we certainly have never seen before or since.
There seemed to be suddenly a necessity for over a quarter of a million new homes each and every year as new towns were manufactured to replace the old slums and families sought extra space to allow for the baby boom. To meet this, a lot of houses were built-in factories after which assembled on location.
These prefab house came into existence as closely associated with the next number of years as Billy Bremner or perhaps the Beatles. In fact, this became actually something of any exaggeration, simply because they never comprised greater than 15% newest builds in an era where high rises were a larger game changer.
In early 1970s, prefabs suddenly went out of style, with good rises not far behind. The demand for such speedy building had reduced. Insurance companies had begun refusing to insure them as it became clear there were numerous problems with the building techniques 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 setting up a comeback – though nowadays it will always be called off-site construction. If the momentum keeps increasing, it will come to dominate house building throughout the UK and perhaps elsewhere in ways that 06dexspky happened from the 1950s and 1960s.
Scotland has been at the forefront. Partly this is certainly as a result of timber frame housing, which is more extensive north of your border. Timber frames became popular in Aberdeenshire within the 1980s to satisfy the nascent oil and gas industry, after which gradually spread to many other aspects of Scotland.
In the early 2000s, framing companies began merging with some other players such as insulators and gradually took benefit of their new strength in depth to maneuver into building kit houses offsite. With the pre-recession peak of 2007, off-site new build had grown from under 10% of new Scottish houses to between 25% and 30%.
By that year, the complete variety of new houses being built in britain was around 200,000. Then it fell to just over 110,000 as demand collapsed. After several lean years it is actually around the up again (see image), fuelled by the UK Government’s Aid to Buy scheme.
But many experts agree it is going to have to grow considerably more quickly if we will satisfy demand in the future. The United Kingdom Government estimates which we will have to build 260,000 houses annually in England and Wales between 2015 and 2031 and 35,000 annually in Scotland.

Not simply are these targets way before 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 business sector during the recession and they are not returning;
high average age in some lines of employment, meaning increasing retirement rates;
huge amounts of refurbishment to existing housing stock;
delays to utility connections on work sites;
pressure on prices and workers from demand utilizing sectors for example oil and gas and major infrastructure works well with rail, road and power stations.
When building reduces
Many individuals assume that offsite is the answer. Based on case studies by Build Offsite, the sector body, the savings incorporate a 10% to 15% reduction in the expense of building; and a 40% reduction in vehicle movements.
It can also help with builders’ mounting energy performance requirements. House building is put under the microscope in recent times to find out where improvements can be done – by way of example one recent research area has been improving buildings’ external insulated fabric.
Off-site manufacturing helps with this since it gives builders additional control over each stage of the construction process. It also means you may reduce waste and possess better control over the kinds of waste being generated, while implementing techniques loved by other sectors such as just-in-time delivery.
To utilize this potential, steel workshop including Kingspan, CCG and Stewart Milne have been investing heavily in facilities during the recession years.
Inspired from the lean construction models of car makers including 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; when in Scotland it is actually now 50 plusPercent.

Through the help of 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 which will include smart technology, intelligent membranes as well as 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 brand new Scottish homes is going to be built in this way, while the rest of the UK will demonstrate exactly the same upward momentum. A number of the light steel villa 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 the 1st time around, this time around promises to be really different. Simply do the construction industry a favour: don’t think of it prefab.
