Not my style, and its certainly not a tiny/small house, but there are some GREAT design ideas within and this video stands as a representation of just what CAN be done with 8' wide shipping containers. I especially love the kitchen in this home, which I would guess is 20' long (most containers come in 20' increments- usually 20' and 40'). Containers such as these (used) can be purchased and delivered for as little as $2000, if you shop around.
I always thought a container in a remote area would be ideal- they're more or less bullet-proof, and burglar proof (when initially constructing them (no windows), and if building a vacation cabin away from home, you can simply leave your tools and materials locked-up within for extended periods of time when you're away. Of course, if zombies n' werewolves attack, you have a better chance holing up in one of these (as long as you board up some windows) as well...just a side perk of "going container".
