I have never seen a three-story house quite like the Small Box House. Designed by Japanese architects Akasaka Shinichiro Atelier, the Small Box House is a three-story house with each level connected via ladder. No stairs, no fireman's pole -- just ladders.

The Small Box House was designed specifically for a couple who desired a casual house that could also one day be converted into a cafe. The second floor of the Small Box House is a living room and bedroom, while the third floor houses a mezzanine. Although the house has some obvious inconveniences -- namely climbing up and down ladders all day -- I really like the open design. This house has almost no doors, which allows for greater family interaction. It also paves the way for teenagers to begin kicking down ladders instead of slamming doors shut when they want a little privacy.
