Good post.
I read about the Sears homes. I think they were called “Lustron” and were some of the first buildings to use a lot of steel. I remember graduating in 84 and reading a light steel brochure that touted the benefits of steel construction. I have built a few stick built homes with help and always thought there had to be a better way.
My #1 son and #2 son work together now still doing stick built homes. About the only big difference now is back in the day I used a hammer to drive nails. Now it is a nail gun.
the tiny homes idea is an interesting one to me as I have a 424 sq ft building currently used as an office but I have been trying to figure out how to make it a home. Adding a bath, Kitchen water and sewage would do it. already has lots of electricity and AC.
