Inside the late 1950s, more than a decade right after the war instead of a long time after the rock and roll explosion, Britain embarked over a house-building programme the like of which we have now never seen before or since.
There is suddenly a necessity for more than a quarter of your million new homes annually as new towns were created to replace the old slums and families sought extra space to allow for the infant boom. To meet this, numerous houses were built in factories and then assembled on location.
These prefabricated house came to be as closely of the next few years as Billy Bremner or even the Beatles. In reality, this is actually something of any exaggeration, since they never comprised over 15% of the latest builds within an era where high rises were a greater game changer.
In the early 1970s, prefabs suddenly went out of style, with good rises not far behind. The demand for such speedy building had reduced. Insurance carriers had begun refusing to insure them because it became clear that there were a lot of troubles with the development techniques that they can would not last nearly as 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 these days it is always referred to as off-site construction. If the momentum keeps increasing, it is going to visit dominate house building across the UK and perhaps elsewhere in ways that 06dexspky happened within the 1950s and 1960s.
Scotland is at the forefront. Partly this really is as a result of timber frame housing, which is more extensive north of your border. Timber frames became popular in Aberdeenshire within the 1980s to satisfy the nascent oil and gas industry, after which gradually spread to many other parts of Scotland.
In the early 2000s, framing companies began merging along with other players like insulators and gradually took advantage of their new strength in depth to move into building kit houses offsite. With the pre-recession peak of 2007, off-site new build had grown from under 10% of most new Scottish houses to between 25% and 30%.
By that year, the entire quantity of new houses being built in the UK was around 200,000. This fell to merely over 110,000 as demand collapsed. After a couple of lean years it can be around the up again (see image), fuelled from the UK Government’s Help to Buy scheme.
But many experts agree it will have to grow a lot more quickly if we are going to satisfy demand in the future. Great Britain 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 simply are these targets way prior to whatever we were building even throughout the pre-recession peak, there are numerous other pressures on construction:
replacing skilled workers who definitely have left the market sector throughout the recession and they are not returning;
high average age in certain 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 using their company sectors like oil and gas and major infrastructure works best for rail, road and power stations.
When building reduces
Many people believe that offsite is the answer. Based on case studies by Build Offsite, the sector body, the savings add a 10% to 15% lowering of the price of building; plus a 40% lowering of vehicle movements.
It also helps with builders’ mounting energy performance requirements. House building has become put beneath the microscope lately to find out where improvements can be produced – for instance one recent research area has become improving buildings’ external insulated fabric.
Off-site manufacturing helps with this mainly because it gives builders additional control over each stage of your construction process. Additionally, it means you are able to reduce waste and possess better power over the types of waste being generated, while implementing techniques well-liked by other sectors such as just-in-time delivery.
To utilize this potential, steel warehouse including Kingspan, CCG and Stewart Milne have been investing heavily in facilities through the recession years.
Inspired with the lean construction models of auto producers 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; during Scotland it really is now 50 plusPercent.

By using the likes for 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 even nanotech. To reflect 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, a lot more than 70% of brand new Scottish homes will likely be built in this way, while the remainder of the UK will demonstrate exactly the same upward momentum. Several of the prefabricated homes are also attracting interest from China, Europe, Brazil and Russia, where this segment has yet to consider off.
Having got off-site construction so wrong the 1st time around, this period promises to be really different. Simply do the property industry a favour: don’t consider it prefab.
