In 2021, the modular construction market was valued at more than $40 billion. The growth trajectory for this type of construction is expected to continue at 8% in the next five years.[i] This encompasses a spectrum of segments including commercial, industrial, and residential.
Defining Modular Construction in the Residential Segment
In the residential segment, there are a few terms that are often used to describe offsite construction – modular, manufactured, and panelized – but there are key differences that distinguish each.
Modular homes are built in sections in a controlled factory setting and then transported to the building site. After the sections are delivered, the components are pieced together and connected to the foundation. This is a permanent type of construction, and the final home must meet the requirements of the International Residential Code, just like a traditional stick-built home.
Panelized or non-volumetric construction is a type of modular construction. Two-dimensional elements, like wall panels, are built offsite and transported to the jobsite. While transportation costs are more favorable, this type of construction requires more work onsite compared to volumetric construction where components are fully enclosed.
Manufactured homes are different than modular homes as the entire home is assembled off-site and then transported to a final site. Manufactured homes must be built to the federal Housing and Urban Develop (HUD) Code.[ii] These homes offer a lower-cost solution and are typically characterized as an affordable housing option. A mobile home is an example of a manufactured home.
What’s the Benefit?
One of the main attractions of modular construction is its ability to boost productivity across building operations. It can accelerate project timelines by up to 50 percent due to less labor and equipment demands and optimized scalability.
Beyond improved productivity and shortened timelines, here are a few other benefits:
Building for Resilience
Modular homes are built to withstand the rigors and stresses of being transported and assembled. In the same way, they can be designed to withstand extreme weather conditions with resilient building practices in mind. In a controlled environment, manufacturers along with researchers, can evaluate foundations, building envelopes, and heating systems that can withstand climate-related threats.
