Prefabricated is a word that means something is made in advance and ready for use. To convey the same meaning in different words, several synonyms can come in handy. Among them are pre-built, pre-fab, modular, pre-manufactured, pre-engineered, and off-site constructed. These synonyms are regularly applied in the construction industry, where prefabricated materials and buildings have gained popularity. They all describe products that are made off-site and generally transported to the building site for installation. These synonyms are useful in making communication more diverse, colorful, and easier to understand by those not familiar with the term prefabricated.
