Either it's some irony, joke or pun, or it's a mistake already mentioned in 10060;pornatil. Even so, although it is misspelled and in the plural, I comment that in Córdoba ("Spain") the 'portable houses' could be a locution, a name for a provisional-parasiempre housing complex that was created with prefabricated housing to accommodate the victims of the flood of 1963 for 18 months, and that already converted into the Las Moreras neighborhood remained for 30 years.
