世界各地的“蜗居”

We're watching a trend here in America and around the crowded world. People ready to live in houses only a couple of feet wide, ABC's Nick Wart shows us life inside the microhome of the future.

Sick and tired of your cramped quarters, stretch out and look at this, a tiny sliver of 156 square feet, just 36 inches widing places. Shark might squeeze through the front door, but I'm thinking he gets stuck in that bathroom. There's a table for two, cozy by candle light, but a bed just for one.

I think plenty of light is most important, says the experimental architect Yaku Sheshezni.

Designed for this guy, Ediker Karet, an Israeli writer reclaiming his Polish roots. And how much space do we really need, the tiny house movement is gaining some traction.

This is my tiny house.

Here's poster boy Jay Shafren.

It sleeps too really comfortably.

Oh, it is small.

This model microapartment in San Francisco toured by our very own Cecilia Viga.

You can almost from the bathroom, reach and grab something in the fridge, that's convenient. That place is just 150 square feet.

The world's population is exploding, we're getting bigger, we'll soon be vacationing in Japanese style capsule hotels, driving a mini-scale Peel P50 and stroking descendants of Mr. Peebles, the world's smallest cat. The average family home in the US is shrinking,but it's still over 2300 square feet. that's 15 times the size of our polish Pied Terrier.
