The number of people actually living in one, I can count on less than three hands. But that will change quite quickly. Several of the architects have sold dozens of homes.

A surprising number are older, retiring baby boomers.

This is really an economy-of-scale question. This is a niche market.

There's still a widely held misconception that anything built in a factory is a trailer home. That's a stigma of prefab that we have to overcome.

What's changing and why more people will adopt this, is choices in housing. As long as there are people unhappy with the status quo in housing choices, there will be an opportunity for well-built prefab or factory-built housing.
