10-12 years ago, I got seriously involved in the tiny house on wheels community, and spent a lot of time seriously thinking about house design and the ramifications of the THoW movement.
My ultimate design settled on an 8' x 16 ' floorplan, with a 4' screenable front porch/greenhouse extension.
This, I judged, was the bare minimum size that could support 2 adults and 1 small child.
It would sleep 2 in the loft and fit a standard 52" crib mattress on the main level.
