I would imagine some rooms will be double-wide. more seriously, it seems mobile homes nowadays come in 14, 16 and 18' widths and 66 to 80' lengths. It seems shipping containers are 8' wide and usually 20, 40 and 45' long. I suspect there are ways to make multiples of these dimensions. I also wonder why you couldn't just take a truck and load it up with a stack of walls that are laid out with a crane.
