Completion of prefabricated houses usually requires a 50% reduction in construction time
During the 1970s, prefab was huge. Designers and builders recognized that they could save time and build cheaper and more accurately if they produced homes in factories. So why are there so few prefab houses today?
From movie stars to environmental activists, the idea of prefab housing is gaining traction. Forward-thinking builders and architects have begun to embrace prefab building. Homes built offsite can be considerably cheaper and faster to put up. “The real saving is in time,” says Brian Abramson, co-founder and director of Method Homes. “It typically takes 50 percent less construction time to complete a prefab house.”
That’s because factory construction is automated and, since its indoors, won’t be subject to weather delays. Factories are able to more accurately predict delivery dates and homes just need to be assembled onsite, which reduces labor costs.
While the precision that working in a factory affords, prefab construction lends itself to the clean lines of modern architecture, but factory construction is able to handle any style of architecture.
The process of designing and building prefab homes doesn’t differ much from traditional homes. Once the property is acquired and mapped, the architect will design the home. Permits are obtained and the builder then works with the factory to complete the building elements and transport them to the site where they are assembled.
Prefab homes aren’t without their issues; permitting can take longer as some areas aren’t accustomed to these kinds of homes and transportation down narrow roads can make delivery difficult.
