In the late 1950s, over a decade once the war and never long after the rock and roll explosion, Britain embarked over a house-building programme the like which we have now never seen before or since.
There is suddenly a necessity for more than a quarter of a million new homes each year as new towns were designed to replace the previous slums and families sought extra room to allow for the baby boom. To fulfill this, numerous houses were internal factories and then assembled on location.
These prefab house came into existence as closely associated with the next number of years as Billy Bremner or maybe the Beatles. In fact, this became actually something of your exaggeration, given that they never comprised more than 15% newest builds in an era where the high rises were a larger game changer.
During the early 1970s, prefabs suddenly went away from style, rich in rises not far behind. The need for such speedy building had reduced. Insurance companies had begun refusing to insure them as it became clear that there were numerous problems with the development techniques that they can 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 currently it is usually referred to as off-site construction. In case the momentum keeps increasing, it will arrived at dominate house building all over the UK and perhaps elsewhere in a manner that 06dexspky happened within the 1950s and 1960s.
Scotland continues to be at the forefront. Partly this is certainly due to timber frame housing, which is more extensive north of your border. Timber frames became popular in Aberdeenshire inside the 1980s to satisfy the nascent oil and gas industry, and after that gradually spread with other elements of Scotland.
Through the early 2000s, framing companies began merging along with other players including insulators and gradually took good thing about their new strength thorough to advance into building kit houses offsite. Through 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 complete number of new houses being built throughout the uk was around 200,000. That fell to merely over 110,000 as demand collapsed. After a couple of lean years it really is about the up again (see image), fuelled from the UK Government’s Aid to Buy scheme.
But most experts agree it may have to develop much more quickly if we will satisfy demand in the future. Great Britain Government estimates that people should build 260,000 houses each and every year in England and Wales between 2015 and 2031 and 35,000 each year in Scotland.

Not simply are these targets way in front of whatever we were building even during the pre-recession peak, there are various other pressures on construction:
replacing skilled workers who may have left the marketplace sector in the recession and are not returning;
high average age in a few lines of labor, 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 from other sectors like oil and gas and major infrastructure works best for rail, road and power stations.
When building stops working
A lot of people feel that offsite will be the answer. In accordance with case studies by Build Offsite, the sector body, the savings feature a 10% to 15% decrease in the cost of building; plus a 40% reduction in vehicle movements.
It may also help with builders’ mounting energy performance requirements. House building has become put beneath the microscope recently to find out where improvements can be done – for instance one recent research area is improving buildings’ external insulated fabric.
Off-site manufacturing aids in this since it gives builders more control over each stage of your construction process. Additionally, it means you may reduce waste and have better power over the kinds of waste being generated, while implementing techniques favored by other sectors for example just-in-time delivery.
To employ this potential, steel structure warehouse like Kingspan, CCG and Stewart Milne have already been investing heavily in facilities through the recession years.
Inspired by the lean construction models of car manufacturers for example 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 numerous many other materials; when in Scotland it is 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 that may include smart technology, intelligent membranes and even nanotech. To mirror these new 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, over 70% of brand new Scottish homes will likely be built this way, while all of those other UK will show the identical upward momentum. A number 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 first time around, this time around promises to be very different. Simply do the property industry a favour: don’t think of it prefab.
