Architect's Dream House: Less Than 200 Square Feet 
I think technology is the enabling factor behind the tiny house movement.<p>Books, CDs, movies, photos, files, paperwork, videogames: all compressed down to the size of a hard drive.  So many random gadgets have been replaced by a smart phone, like camera equipment, phones, flashlights, calendars, etc.  Now people are ditching TVs as well and just using iPads and laptops to watch video.<p>There are other more subtle things as well.  For example, I haven't needed to iron a shirt in years because nice shirts come out of the dryer looking perfect.  So no need for an iron or ironing board.<p>Then there's service-economy-ification.  Most of my neighbors don't mow their own lawn, none of them fix their own cars, and several don't even clean their own house.  I wonder how many brew their own coffee?  That's a huge amount of equipment that is no longer needed.  When I lived in New York, literally 100% of my local friends used wash-and-fold and owned nothing to take care of clothing.  A close friend of mine confessed recently that he hasn't prepared a real meal in years; his kitchen cabinets are nearly empty.<p>The sharing economy is pushing this further.  There's a tool-share co-op in my city for those things you need once-in-a-while, like a ladder.  Car2Go and ZipCar mean people don't need 2 and 3 car garages at all anymore.<p>I can't wait to get rid of more stuff!
