A modular home is a prefabricated structure built in sections and assembled on-site. It consists of:

Foundation & Support: Typically elevated on piers or beams, with floor joists distributing weight.
Framing System: Lightweight steel or timber walls with vertical studs for stability.
Roofing: Prefabricated pitched roof with rafters and cleats for durability.
Modular Assembly: Interlocking joints and fasteners ensure secure connections.
