Inside the late 1950s, greater than a decade after the war instead of long after the rock and roll explosion, Britain embarked on a house-building programme the like which we now have never seen before or since.
There is suddenly a need for over a quarter of your million new homes annually as new towns were designed to replace the existing slums and families sought more space to accommodate the baby boom. To satisfy this, numerous houses were integrated factories then assembled on location.
These prefab house came into existence as closely associated with the next couple of years as Billy Bremner or maybe the Beatles. In fact, this became actually something of an exaggeration, since they never comprised over 15% of the latest builds in a era where the high rises were a larger game changer.
In the early 1970s, prefabs suddenly went out of style, with good rises not far behind. The requirement for such speedy building had reduced. Insurance carriers had begun refusing to insure them mainly because it became clear that there were a lot of difficulties with the building techniques that they can 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 building a comeback – though nowadays it will always be referred to as off-site construction. In the event the momentum keeps increasing, it will come to dominate house building over the UK as well as elsewhere in a way that 06dexspky happened within the 1950s and 1960s.
Scotland has become leading the way. Partly this can be due to timber frame housing, which is more extensive north from the border. Timber frames became popular in Aberdeenshire inside the 1980s to satisfy the nascent oil and gas industry, then gradually spread for some other aspects of Scotland.
From your early 2000s, framing companies began merging with some other players for example insulators and gradually took benefit of their new strength comprehensive 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 throughout the uk was around 200,000. It fell just to over 110,000 as demand collapsed. After a couple of lean years it can be on the up again (see image), fuelled with the UK Government’s Aid to Buy scheme.
But most experts agree it is going to have to cultivate a lot more quickly if we will satisfy demand for the future. The UK Government estimates that we should build 260,000 houses each year in England and Wales between 2015 and 2031 and 35,000 each and every year in Scotland.

Not merely are these targets way ahead of what we were building even during the pre-recession peak, there are various other pressures on construction:
replacing skilled workers who may have left the business sector throughout the recession and therefore are not returning;
high average age in many lines of work, 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 off their sectors including oil and gas and major infrastructure works best for rail, road and power stations.
When building fails
Many individuals believe that offsite will be the answer. Based on case studies by Build Offsite, the sector body, the savings incorporate a 10% to 15% lowering of the fee for building; as well as a 40% lowering of vehicle movements.
It also helps with builders’ mounting energy performance requirements. House building has become put under the microscope in recent times to understand where improvements can be done – for instance one recent research area has been improving buildings’ external insulated fabric.
Off-site manufacturing helps with this as it gives builders more control over each stage in the construction process. It also means it is possible to reduce waste and have better power over the sorts of waste being generated, while implementing techniques popular with other sectors like just-in-time delivery.
To take advantage of this potential, steel structure warehouse such as Kingspan, CCG and Stewart Milne have been investing heavily in facilities in the recession years.
Inspired by the lean construction kinds of car manufacturers including 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 various other materials; when in Scotland it really is now over 50Percent.

With 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 which will include smart technology, intelligent membranes and in many cases 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, more than 70% of the latest Scottish homes is going to be built in this way, while the remainder of the UK shows the identical upward momentum. A number of the light steel villa will 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 very first time around, this period promises to be very different. Accomplish your building industry a favour: don’t call it prefab.
