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%.
