Prefabricated Modular homes

Prefabricated homes are a popular choice in the housing market

Prefab (prefabricated) homes are becoming more popular
prefabricated homes
with the wide variety of design choices and fast construction. Since they are built in a controlled environment they do not have the construction hazards that houses built in an open environment encounter.  Many models and designs are available. They are no longer a basic dwelling and purchasers can choose from many interior and exterior plans. Most can be ready for occupation from 1-3 months from the start of conception. With upgraded standards they are now allowed in many locations where they were previously excluded from in the past. The housing market has seen substantial growth in the industry as they provide considerable savings for the new home owner.

Prefab homes, are dwellings manufactured off-site in advance, usually in standard sections that can be easily shipped and assembled. Some current prefab home designs include architectural details inspired by postmodernism or futurist architecture.

The word "Prefab" is not an industry term like modular home, manufactured home, panelized home, or site-built home. The term is an amalgamation of panellized and modular building systems, and can mean either one. In today's usage the term "Prefab" is more closely related to the style of home, usually modernist, rather than to a particular method of home construction.

In the United Kingdom the word "Prefab" is often associated with a specific type of prefabricated house built in large numbers after the WW ll as a temporary replacement for housing that had been destroyed by bombs. Some of them are still in use in the 21st Century.

A new development of modern prefabricated homes are currently being built in Milton Keynes, England. Designed by renowned architect Richard Rogers, designer of the Lloyd's building, the Millennium Dome and the Pompidou Centre in Paris, these new 'prefab' homes are part of a wider government objective to breathe new building methods into the housing market within the United Kingdom and show that 'Prefab' is not only still alive, but also well respected.

The prefab home or house requires much less labour as compared to conventional houses or homes. Most of the companies are selling complete pre-manufactured prefab modular homes or houses called "mobile homes" or "manufactured homes". Prefab homes are becoming popular in Europe, Canada and United States as they are cheap. Local building codes in the US do not apply to prefab homes or houses; instead, these houses are built according to specialized guidelines (Federal HUD regulations) for manufactured housing. Manufactured homes are not permitted in some communities and therefore, one should check from their local city to find about prefab building and construction laws regarding prefab homes before considering purchase.

Prefab assembly

The conventional method of building a house is to transport bricks, timber, cement, sand, steel and construction aggregate, etc to the site, and to construct the house on site from these materials. In prefabricated construction, only the foundations are constructed in this way, while sections of walls, floors and roof are prefabricated (assembled) in a factory (possibly with window and door frames included), transported to the site, lifted into place by a crane and bolted together.

Prefabrication is used in the manufacture of ships, aircraft and all kinds of vehicles and machines where sections previously assembled at the final point of manufacture are assembled elsewhere instead, before being delivered for final assembly.

The theory behind the method is that time and cost is saved if similar construction tasks can be grouped, and assembly line techniques can be employed in prefabrication at a location where skilled labour is available, while congestion at the assembly site, which wastes time, can be reduced. The method finds application particularly where the structure is composed of repeating units or forms, or where multiple copies of the same basic structure are being constructed.

Prefabrication avoids the need to transport many skilled workers

to the construction site, and other restricting conditions such as a lack of power, lack of water, exposure to harsh weather or a hazardous environment are avoided.
