Storja
Buildings have been built in one place and reassembled in another throughout history. This was especially true for mobile activities, or for new settlements. Kastell Elmina, the first forti tal-iskjavi in Afrika tal-Punent, was also the first European prefabricated building in Afrika sub-saħarjana.1: 93 In L-Amerka ta 'Fuq, in 1624 wieħed mill-ewwel bini at Cape Ann was probably partially prefabricated, and was rapidly disassembled and moved at least once. John Rollo described in 1801 earlier use of portable hospital buildings in the West Indies.2 Possibly the first advertised prefab house was the "Manning cottage". A London carpenter, Henry Manning, constructed a house that was built in components, then shipped and assembled by British emigrants. This was published at the time (advertisement, South Australian Record, 1837) and a few still stand in Australia.3 One such is the Dar tal-Laqgħa tal-Ħbieb, Adelaide.45 The peak year for the importation of portable buildings to Australia was 1853, when several hundred arrived. These have been identified as coming from Liverpool, Boston and Singapor (with Chinese instructions for re-assembly).6 In Barbados the Dar taċ-ċatt was a form of prefabricated building which was developed by emancipated slaves who had limited rights to build upon land they did not own. As the buildings were moveable they were legally regarded as oġġetti mobbli.7
In 1855 during the Gwerra tal-Krimea, after Florence Nightingale wrote a letter to The Times, Isambard Renju Brunel was commissioned to design a prefabricated modular hospital. In five months he designed the Isptar Renkioi: sptar ta' pazjent 1,000, b'innovazzjonijiet fis-sanità, ventilazzjoni u toilet tal-flushing.8 Fabricator William Eassie constructed the required 16 units in Baċiri ta' Gloucester, shipped directly to the Dardanelli. Użat biss minn Marzu 1856 sa Settembru 1857, naqqas ir-rata tal-mewt minn 42 fil-mija għal 3.5 fil-mija.
The world's first prefabricated, pre-cast panelled apartment blocks were pioneered in Liverpool. A process was invented by city engineer John Alexander Brodie, whose inventive genius also had him inventing the football goal net. The tram stables at Walton in Liverpool followed in 1906. The idea was not extensively adopted in Britain, however was widely adopted elsewhere, particularly in Eastern Europe.
Prefabricated homes were produced during the Gold Rush in the United States, when kits were produced to enable Californian prospectors to quickly construct accommodation. Homes were available in kit form by mail order in the United States in 1908.9
Prefabricated housing was popular during the It-Tieni Gwerra Dinjija due to the need for mass accommodation for military personnel. The United States used Quonset barrakki as military buildings, and in the United Kingdom prefabricated buildings used included Nissen barrakki and Qniepen Hangars. 'Prefabs' were built after the war as a means of quickly and cheaply providing quality housing as a replacement for the housing destroyed during il-Blitz. The proliferation of prefabricated housing across the country was a result of the Kumitat Burt and the Att tal-1944 tad-Djar (Akkomodazzjoni Temporanja).. Under the Ministeru tax-Xogħlijiet Fabbrika ta 'Emerġenza Magħmula housing programme, a specification was drawn up and bid on by various private construction and manufacturing companies. After approval by the MoW, companies could bid on Council led development schemes, resulting in whole estates of prefabs constructed to provide accommodation for those made homeless by the War and ongoing tneħħija tas-slum.10 Almost 160,000 had been built in the UK by 1948 at a cost of close to £216 million. The largest single prefab estate in Britain11 was at Belle Vale (South Liverpool), where more than 1,100 were built after World War 2. The estate was demolished in the 1960s amid much controversy as the prefabs were very popular with residents at the time.
Prefabs were aimed at families, and typically had an entrance hall, two bedrooms (parents and children), a bathroom (a room with a bath) — which was a novel innovation for many Britons at that time, a separate toilet, a living room and an equipped (not imwaħħal in the modern sense) kitchen. Construction materials included steel, aluminium, timber or asbestos, depending on the type of dwelling. The aluminium Tip B2 prefab was produced as four pre-assembled sections which could be transported by lorry anywhere in the country.12
The Universal House (pictured left lounge diner right) was given to the Mużew tal-Ajru Miftuħ ta’ Chiltern after 40 years temporary use. The Mark 3 was manufactured by the Universal Housing Company Ltd, Rickmansworth.
The United States used prefabricated housing for troops during the war and for GIs returning home. Prefabbrikat classrooms were popular with UK schools increasing their rolls during the baby boom of the 1950s and 1960s.
Many buildings were designed with a five-ten year life span, but have far exceeded this, with a number surviving today. In 2002, for example, the city of Bristol still had residents living in 700 examples.13 Many UK councils have been in the process of demolishing the last surviving examples of Second World War prefabs in order to comply with the British government's Djar Diċenti Standard, which came into effect in 2010. There has, however, been a recent revival in prefabricated methods of construction in order to compensate for the United Kingdom's current housing shortage.ċitazzjoni meħtieġa
Prefabbrikati u l-moviment modernist
Il-periti qed jinkorporaw disinji moderni fid-djar prefabbrikati tal-lum. L-akkomodazzjoni prefabbrikata m'għandhiex tibqa 'tqabbel ma' dar mobbli f'termini ta 'dehra, iżda ma' dik ta 'disinn modernista kumpless.14 There has also been an increase in the use of "green" materials in the construction of these prefab houses. Consumers can easily select between different environmentally friendly finishes and wall systems. Since these homes are built in parts, it is easy for a home owner to add additional rooms or even solar panels to the roofs. Many prefab houses can be customized to the client's specific location and climate, making prefab homes much more flexible and modern than before.
There is a zeitgeist or xejra in architectural circles and the spirit of the age favors the small marka tal-karbonju of "prefab".
Effiċjenza
The process of building pre-fabricated buildings has become so efficient in China that a builder in Changsha built a ten-sular building in 28 hours and 45 minutes.15 16

Many eastern European countries had suffered physical damage during Tieni Gwerra Dinjija and their economies were in a very poor state. There was a need to reconstruct cities which had been severely damaged due to the war. For example, Varsavja had been practically razed to the ground under the planned destruction of Warsaw by German forces after the 1944 Rewwixta ta’ Varsavja. The centre of Dresden, il-Ġermanja, kienet ġiet meqruda totalment mill-bumbardament tal-Alleati tal-1945. Stalingrad kien inqered fil-biċċa l-kbira u numru żgħir biss ta’ strutturi tħallew weqfin.
Prefabricated buildings served as an inexpensive and quick way to alleviate the massive housing shortages associated with the wartime destruction and large-scale urbanizzazzjoni and titjira rurali.

McDonald's uses prefabricated structures for their buildings, and set a record of constructing a building and opening for business within 13 hours (on pre-prepared ground works).17
In the UK, the major supermarkets have each developed a modular unit system to shop building, based on the systems developed by German cost retailer Aldi and the Danish supermarket chain Netto.18
