How They’re Made
In a highly engineered manufacturing process, modular homes are built in sections called modules. Once built, the modules undergo a series of quality-control checks in the factory.
After the manufacturing process is complete — typically with interior finish on the floors, walls and ceilings — trucks transport the home to its site, place the modules on a prepared foundation with a crane and join them to the foundation and each other.
While critics have charged that modular homes are too boxy, that refrain is beginning to fade with growing flexibility in design and customization options.
Also, the emerging trend of hybrid modular panelized construction — adding site-built garages, porches and other custom add-ons — gives modular housing a fresh face.
