One Word Challenge Mobile as in Homes
https://en.wikipedia.org/wiki/Mobile_home
“A mobile home (also trailer, trailer home, house trailer, static caravan, residential caravan) is a prefabricated structure, built in a factory on a permanently attached chassis before being transported to site (either by being towed or on a trailer). Used as permanent homes, for holiday or temporary accommodation, they are left often permanently or semi-permanently in one place, but can be moved, and may be required to move from time to time for legal reasons.”
