Inside the late 1950s, greater than a decade following the war and not a long time after the rock and roll explosion, Britain embarked over a house-building programme the like in which we have now never seen before or since.
There seemed to be suddenly a necessity for over a quarter of any million new homes every year as new towns were built to replace the old slums and families sought extra space to support the infant boom. To fulfill this, a lot of houses were integrated factories and after that assembled on location.
These prefabricated house came into existence as closely associated with the next several years as Billy Bremner or perhaps the Beatles. In reality, this was actually something of the exaggeration, given that they never comprised more than 15% newest builds in a era in which the high rises were a much bigger game changer.
During the early 1970s, prefabs suddenly went out of style, rich in rises not far behind. The necessity for such speedy building had reduced. Insurance carriers had begun refusing to insure them mainly because it became clear there were numerous issues with the development techniques which 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 creating a comeback – though nowadays it usually is generally known as off-site construction. In the event the momentum keeps increasing, it will go to dominate house building all over the UK and possibly elsewhere in a manner that 06dexspky happened within the 1950s and 1960s.
Scotland continues to be at the forefront. Partly this can be because of timber frame housing, which is more extensive north from the border. Timber frames became popular in Aberdeenshire from the 1980s to fulfill the nascent oil and gas industry, after which gradually spread for some other parts of Scotland.
From the early 2000s, framing companies began merging with many other players such as insulators and gradually took advantage of their new strength comprehensive to maneuver into building kit houses offsite. By 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 whole variety of new houses being built in the united kingdom was around 200,000. That fell to simply over 110,000 as demand collapsed. After several lean years it is around the up again (see image), fuelled through the UK Government’s Help to Buy scheme.
But the majority experts agree it is going to have to develop far more quickly if we will satisfy demand in the future. The UK Government estimates which we should build 260,000 houses annually in England and Wales between 2015 and 2031 and 35,000 each and every year in Scotland.

Not merely are these targets way before what we were building even throughout the pre-recession peak, there are many other pressures on construction:
replacing skilled workers that have left the business sector during the recession and therefore are not returning;
high average age in a few lines of employment, 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 from other sectors including oil and gas and major infrastructure works well with rail, road and power stations.
When building reduces
A lot of people assume that offsite will be the answer. As outlined by case studies by Build Offsite, the sector body, the savings add a 10% to 15% decline in the price of building; along with a 40% decrease in vehicle movements.
It also helps with builders’ mounting energy performance requirements. House building continues to be put underneath the microscope in recent times to figure out where improvements can be produced – for instance one recent research area has become improving buildings’ external insulated fabric.
Off-site manufacturing aids in this mainly because it gives builders more control over each stage in the construction process. In addition, it means it is possible to reduce waste and have better control over the kinds of waste being generated, while implementing techniques popular with other sectors like just-in-time delivery.
To take advantage of this potential, steel workshop like Kingspan, CCG and Stewart Milne have already been investing heavily in facilities in the recession years.
Inspired from the lean construction designs of auto producers 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; while in Scotland it is actually now 50 plusPercent.

Through the help of the likes for 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 may 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 undoubtedly keep growing. Chances are that by 2017, a lot more than 70% of brand new Scottish homes will probably be built this way, while the other UK will show a similar upward momentum. Several of the light steel villa will 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 period promises to be very different. Do the construction industry a favour: don’t think of it prefab.
