Totally awesome http://www.fastcoexist.com/3036734/this-micro-apartment-transforms-when-you-push-a-button-to-give-you-more-space.  In some of my really old note books I drew and described my “dream” house with fold/slide/pop out furniture, games, beds, walls etc.  I never thought of it actually being developed.  Their target market is for apartments in cities with cramped living conditions.  Which is perfect!

One of the concerns I had identified was the fragility with a system like this.  If  one of the hinges breaks I wouldn’t be able to get my bead out.  Also, I had assumed it would all be done at a press of a button and we could program different configurations.  Problem was what if the power went out.

Still I think it is a clever concept that I hope gets popular even in standard size houses.
