I ran across this interesting article today.
The website is from John Pratt where he is mostly discussing calendars and such, but this page come from his (now deceased) brother James Pratt.
Here he discusses affordable housing, including topics like construction, debt, fiat currency and others related to building a single family home.
I found his ideas interesting and in line with much of my thinking in this area.
(his specific instructions for heating and cooling are applicable to his area - Utah)
