“More than a third of the average American’s after-tax income is devoted to shelter, usually rent or mortgage payments. If a person works from age 20 to age 65, it can be fairly argued that he or she has put in 15 years (20 in California) just to keep a roof over their head. With a piece of land, six months’ work, and — say — $35,000, he (or she) and his family could have built his own home.
To save 14½ years of work, you cannot afford not to build, even if it means losing a job while you do it. Granted, the land (and the $35,000) has to come from somewhere, but this amount is no more (and probably no less) than the down payment on a mortgaged contractor-built home, and about half the cost of a new double-wide mobile home (figuring either option as being about the same square footage as an earth-sheltered home).
So… why don’t more people do it? Is it really worth giving up 15+ years of your life (and I’d say for many people, more) to pay off the house you live in just to save yourself the effort of having to do it yourself? Surely it can’t be that a life of 9-to-5 indentured servitude is so wonderful that one can’t give up a summer or three building a house like the one above, which I believe came in at about $20,000… And with an increasing percentage of people defaulting on their mortgages and losing all of those years, even on a risk management level it seems completely nonsensical.”

“An earth-sheltered, earth-roofed home has the least impact upon the land of all housing styles, leaving almost zero footprint on the planet.
Earth-Sheltered Houses is a practical guide for those who want to build their own underground home at moderate cost. It describes the benefits of sheltering a home with earth, including the added comfort and energy efficiency from the moderating influence of the earth on the home’s temperature (keeping it warm in the winter and cool in the summer), along with the benefits of low maintenance and the protection against fire, sound, earthquake, and storm afforded by the earth. Extra benefits from adding an earth or other living roof option include greater longevity of the roof substrate, fine aesthetics, and environmental harmony.”
