The popularity of tiny homes is anything but small. The trend is being reinvented in many different ways - luxury, basic, affordable, high tech, 3D printed - and even is inspiring a new interpretation of building code.

The demand for living small is getting bigger.

More than half of Americans would consider living in a home that's less than 600 square feet, according to a survey done by the National Association of Home Builders. And among Millennials, interest increases to 63%.

"Tiny is inevitable," says Soren Rose, founder of Klein, which in 2017 began seeking out renowned architects to design tiny prefab homes.

"You see these amazing tiny houses in magazines and on television programs, but you can't really buy them," says Rose. "Architects did it for themselves to prove how they can make a gem.
