Home construction, in the early 1900s, was based on home-building kits. Supplies arrived on site ready to assemble. It was the start of modular construction.

The global modular construction market was estimated at $104.01 billion as of 2024. And it is expected to grow from 171 billion in 2025 to 307 billion by 2035.

What are the differences between modular construction and prefabrication?

Modular means that 60-90% of the structure is built off-site, transported to the site, and assembled on-site. Prefabrication involves building and assembling specific kits off-site and attaching them to the building later. These two construction methods would address the following issues associated with construction:

• eliminating waste
• reducing transportation
• diminishing carbon emissions
• streamlining processes, which can speed up the construction cycle
• improving efficiency thanks to fewer errors
• avoiding budget overruns.
