Within the late 1950s, greater than a decade once the war instead of a long time after the rock and roll explosion, Britain embarked on a house-building programme the like of which we have never seen before or since.
There seemed to be suddenly a necessity for more than a quarter of the million new homes each year as new towns were created to replace the previous slums and families sought extra space to fit the child boom. To meet this, many houses were built-in factories and then assembled on location.
These prefab house came to be as closely of the next several years as Billy Bremner or perhaps the Beatles. In truth, this became actually something of your exaggeration, since they never comprised more than 15% of new builds inside an era where the high rises were a much bigger game changer.
During the early 1970s, prefabs suddenly went from 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 difficulties with the building techniques that 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 making a comeback – though these days it is always called off-site construction. In case the momentum keeps increasing, it is going to come to dominate house building over the UK as well as elsewhere in a fashion that 06dexspky happened from the 1950s and 1960s.
Scotland is leading the way. Partly this is certainly thanks to timber frame housing, which is more extensive north from the border. Timber frames became popular in Aberdeenshire within the 1980s to fulfill the nascent oil and gas industry, after which gradually spread to many other areas of Scotland.
From your early 2000s, framing companies began merging with many other players including insulators and gradually took advantage of their new strength comprehensive to move 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 whole amount of new houses being built throughout the uk was around 200,000. Then it 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 by the UK Government’s Help to Buy scheme.
But a majority of experts agree it may have to grow considerably more quickly if we will satisfy demand for the future. The United Kingdom Government estimates which we will have to build 260,000 houses each and every 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 were building even in the pre-recession peak, there are several other pressures on construction:
replacing skilled workers that have left the market sector in the recession and are not returning;
high average age in some lines of employment, meaning increasing retirement rates;
large 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 best for rail, road and power stations.
When building stops working
Many people think that offsite is definitely the answer. Based on case studies by Build Offsite, the sector body, the savings feature a 10% to 15% reduction in the expense of building; plus a 40% lowering of vehicle movements.
It may also help with builders’ mounting energy performance requirements. House building continues to be put beneath the microscope in recent years to determine where improvements can be created – for instance one recent research area continues to be improving buildings’ external insulated fabric.
Off-site manufacturing assists with this since it gives builders more control over each stage of the construction process. In addition, it means you can reduce waste and have better power over the types of waste being generated, while implementing techniques favored by other sectors including just-in-time delivery.
To employ this potential, steel structure warehouse for example Kingspan, CCG and Stewart Milne are already investing heavily in facilities during the recession years.
Inspired from the lean construction models of car makers 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 other materials; while in Scotland it can be now 50 plusPer cent.

With 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 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 will undoubtedly keep growing. It is likely that by 2017, a lot more than 70% of new Scottish homes will likely be built in this manner, while the rest of the UK can have a similar upward momentum. Some of the light steel villa may also be attracting interest from China, Europe, Brazil and Russia, where this segment has yet to adopt off.
Having got off-site construction so wrong the first time around, this time promises to be really different. Do your building industry a favour: don’t refer to it as prefab.
