In the late 1950s, more than a decade once the war and not long after the rock and roll explosion, Britain embarked over a house-building programme the like of which we now have never seen before or since.
There is suddenly a desire for more than a quarter of any million new homes annually as new towns were built to replace the existing slums and families sought extra space to fit the infant boom. To fulfill this, numerous houses were internal factories and after that assembled on location.
These prefab house came into existence as closely related to the next few years as Billy Bremner or perhaps the Beatles. Actually, this was actually something of any exaggeration, since they never comprised over 15% newest builds in an era the location where the high rises were a much bigger game changer.
In the early 1970s, prefabs suddenly went from style, with high rises not far behind. The necessity for such speedy building had reduced. Insurance companies had begun refusing to insure them mainly because it became clear there were countless issues with the development techniques that they would not last nearly provided 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 setting up a comeback – though currently it is usually called off-site construction. In the event the momentum keeps increasing, it will almost certainly visit dominate house building across the UK and maybe elsewhere in a way that 06dexspky happened in the 1950s and 1960s.
Scotland is at the forefront. Partly this is as a result of timber frame housing, which is more extensive north of the border. Timber frames became popular in Aberdeenshire inside the 1980s in order to satisfy the nascent oil and gas industry, and after that gradually spread to other elements of Scotland.
In the early 2000s, framing companies began merging along with other players including insulators and gradually took benefit from their new strength in depth to move into building kit houses offsite. Through 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 quantity of new houses being built in the UK was around 200,000. That fell just to over 110,000 as demand collapsed. After several lean years it really is around the up again (see image), fuelled with the UK Government’s Help to Buy scheme.
But a majority of experts agree it may have to grow a lot more quickly if we will satisfy demand in the future. The UK Government estimates that we should build 260,000 houses annually in England and Wales between 2015 and 2031 and 35,000 every year in Scotland.

Not simply are these targets way in front of what we should were building even during the pre-recession peak, there are several other pressures on construction:
replacing skilled workers who definitely have left the market sector in 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 utilizing sectors like oil and gas and major infrastructure works best for rail, road and power stations.
When building fails
A lot of people believe that offsite is definitely the answer. As outlined by case studies by Build Offsite, the sector body, the savings add a 10% to 15% decrease in the fee for building; and a 40% decrease in vehicle movements.
It may also help with builders’ mounting energy performance requirements. House building has been put beneath the microscope recently to understand where improvements can be made – for instance one recent research area has been improving buildings’ external insulated fabric.
Off-site manufacturing aids in this since it gives builders more control over each stage from the construction process. Furthermore, it means you can reduce waste and possess better control of the kinds of waste being generated, while implementing techniques well-liked by other sectors like just-in-time delivery.
To employ this potential, steel warehouse like Kingspan, CCG and Stewart Milne have been investing heavily in facilities through the recession years.
Inspired from the lean construction types of car makers such as 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 other materials; whilst in Scotland it really is now over 50Per cent.

Through the help of the likes of the future Construction Scotland Innovation Centre, that can bring together academics and researchers from 11 universities, these manufacturers are developing increasingly advanced assembly techniques that will include smart technology, intelligent membranes as well as 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 simply keep growing. It is likely that by 2017, a lot more than 70% of the latest Scottish homes will be built by doing this, while the rest of the UK shows the same 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 take off.
Having got off-site construction so wrong at the first try around, this time around promises to be really different. Simply do your building industry a favour: don’t consider it prefab.
