Design magazines like prefabricated buildings, as do movie stars and environmental activists.New technologies, including the use of robots in factories, have made prefabricated buildings easier to produce in factories.
So why do proponents of prefabricated homes still talk about their slow progress?
Author Sheri Koones says: "architects, environmentalists and some forward-thinking builders have embraced prefabricated buildings -- products ranging from affordable homes to stylish small houses and ultra-modern renovated mansions -- and every family should opt for prefabricated homes in the future."
Although prefabricated homes have been around for decades, prefabricated or modular homes accounted for just 2 percent of new single-family homes built in the United States in 2016, according to the census bureau.
Prefabricated buildings gained momentum in the 1970s when builders and architects realized that they could save construction time and labor costs by moving most of the construction process to factories. Initially, the shape of the modular home was basically square, but over time, architects, builders and factory owners have refined their approach, and buildings of almost any shape can now be assembled in a factory first, Koons said.
Although light steel prefabricated villa costs less than traditional building houses, but financial savings is not always the people the most compelling reason to choose this construction method."Prefabricated houses usually take 50 percent of the construction time of conventional houses."Building houses in factories can be weatherproof and make delivery dates more predictable.Changing orders is usually not allowed, which also speeds up construction.
Shorter field hours can save labor costs.Prefabricated buildings can save up to 15 to 20 percent of the cost of traditional custom construction."Cool" has also boosted interest in prefabricated homes.
A major turning point for prefab homes came in 2002-03, when Dwell magazine held an architect competition to design a $200,000 prefab home, says Ryan e. Smith, director of collaborative integration technology for architecture at the university of salt lake, Utah.
"Some of the noise around prefabricated buildings continues," says Tanney. "architects need to be guided to create renderings of prefabricated buildings and occasionally build a house. Resolution of the 15 to 20 homes built each year, more than half is prefabricated villa. But the truth is that most prefabricated homes are mediocre, and most modular factories are building traditional types to attract more buyers. And the reason modern prefabricated buildings are exciting is simply because they're more fun."
Easy assembled villa was more common in other countries, especially in Sweden, Japan and Germany.The difference is that they tend to be production-based, so even though they are high-end, all homes look similar. The prefab preference in North America is more custom prefab architecture that has not changed architecture, although it has attracted more interest from outside the architecture community and the quality of architecture has improved over the past 15 years.
Today, modular parts can even be produced by robots in some factories, which solves the current shortage of construction labor. Components can be assembled on site in weeks, not months.
The process of designing and building a prefabricated house requires similar steps to a traditionally built house: finding a lot, designing the house, and obtaining a permit. The difference is that the builder needs to sign a contract with the factory to build the house and transport it to the site, and then the construction workers will provide post work and landscaping. Custom home buyers can work with design and construction companies, hire their own architects, or work with in-house architects of modular house factories.
Like every construction method, prefabricated parts have their troubles. He believes that the prefabricated houses in the factory have excellent building quality and thermal insulation.
National transportation rules also affect the design of prefabricated houses.
Some people say that living in a modular house is no different from living in a traditional house. He has lived in the modular house he built for 19 years. The house takes only four months to complete the occupancy plan, while a traditional house usually takes 6 to 10 months.
Many people are interested in prefabricated houses. Every day a prefabricated house project or prototype is being developed, and investors are excited about prefabricated buildings. But the construction industry has always been difficult to accept. But the construction industry has been slow to accept it. One reason is that, like many industries, because new things are always controversial. People have a greater tendency to do what has already been done.
Whether it's to save time, reduce construction waste, implement a cool design, or externally say your home is made of robots, a prefabricated house will not lack its supporters. But even they acknowledge that it may take years for prefabricated houses to become the most popular way to build a home.
