Blowhard, Esq. writes:

The chattel houses of Barbados and other parts of the British West Indies date back to the nineteenth century, and are possibly the world’s first mobile homes. The word “chattel” means “moveable property” and derives from “cattle” — at one time, this was the only significant piece of property a man would own…

Chattel houses were built entirely of wood and assembled without nails to make them simple to disassemble and move from place to place…As the family expanded and perhaps became more settled, owners often added a couple of rear rooms, or even another house, onto the back.
