Bloomberg's Tiny Houses Big with U.S. Owners Seeking Economic Freedom covers the nascent tiny home movement.
Homes are generally consider tiny if they are less than 500 square feet in total and they can be much smaller - as small as 100 square feet. They're also called micro-homes and as the article points out, most industry analysts think there are only a few thousand in the U.S.
In addition to freestanding micro homes, micro-apartments are also becoming more popular. Generally anything under 400 square feet is considered a micro-apartment and some cities - San Francisco, for example - allow new apartments to be as small as 220 square feet.
So why are people moving to tiny houses and apartments? According to the Tiny Life blog, which covers the tiny house movement:
People are joining this movement for many reasons, but the most popular reasons are because of environmental concerns, financial concerns and seeking more time and freedom.
We consider the tiny house movement another signal of the growth of economic uncertainty, which is leading to more people focusing on how they can live a more modest and sustainable life.
