Panelization falls under the offsite construction umbrella, but it doesn’t solve all the challenges modular building does, according to Mark Dearth of Colorado Building Systems.
Modular building is often held up as a solution to labor challenges, as entire rooms are completed in a factory and shipped to the home site ready to be put in place. With panelization, walls are completed offsite, but have to be assembled when they arrive at the site.
Colorado Building Systems has a provider for panelized housing, but Dearth noted that the “difficult thing about panelized housing is the labor force, is just finding people who are able to put it together.”
Still, it’s a method that is taking off in the resurgent offsite construction world. The Census Bureau tracks the number of homes that are built on site as well as those that use modular or other offsite methods of construction. It found that in 2017, less than 2% of homes around the country were built using panelization or precut components, about the same percentage as modular homes. In the West Census region, panelization was twice as common as modular building, as 1.11% of single-family homes were built using this method, compared to 0.56% that were modular homes.
Dearth noted, “At the end of the day, panelized [housing] certainly cuts down on the cost. It might show up as three different loads, but you still have to have the labor and the crane to continue that construction.”
