Prefabricated homes are used all around the world, and have a long history in many nations. However, the market share for prefab homes is still very small compared to traditional dwellings, despite the low cost of manufacture and the versatility in design. The prefabrication industry is becoming more successful all the time however, both in terms of housing and other buildings such as carports, garages, and industrial structures. Despite their low comparative market share however, prefab homes are becoming more popular in many nations around the world, including the United States, Australia, Canada, and throughout Europe.

One of the main reasons for the rise in popularity of prefabricated homes is the associated costs of manufacture. Since the global economic downturn in 2007, lots of people have been looking for more affordable housing solutions, and prefab homes are recognised by many people as the budget option. However, there are lots of more expensive designer prefab homes also on the market, so it is not a good idea to presume that all prefab structures are cheaper than other alternatives. Especially since the drop in housing prices in 2008, many prefabricated homes are equal to other homes, and some of larger buildings can even cost more per square meter.

There is a strong link between prefabricated building structures and modern architecture, which has been experimenting with prefab homes over the last couple of decades. For modern architects who are concerned with well designed, mass-produced homes, the prefabrication industry offers a suitable and affordable solution. The clean lines and open floor plans of many prefabricated homes lends itself well to many postmodern architectural techniques, as do the use of modern materials and design simplifications. While the market share of the prefabricated home industry is still very small compared to traditional housing structures, it is likely to increase in future years due to continued innovation and lowering manufacturing costs.
