A modular home is a building that is partially constructed offsite in a factory. The factory-built sections, or modules, are transported by truck to the building site. Once onsite, a builder assembles the pieces on a prepared foundation by stacking the modules or laying them side by side or end to end, depending on the design. The finishing work is then completed to the owner’s specifications. Modular homes are sometimes referred to as systems-built or factory-built houses.



Modular homes are good for the environment. The modular home building process is inherently green. The factory system and focus on material utilization mean there is less waste than in traditional building methods.


Structurally, modular buildings are very strong since the components are engineered to be transported and craned into place. As well, the construction quality management is typically higher than in many traditionally-built homes because manufacturing plants have stringent inspection protocols and standard operating procedures.
