Count me in, too. I’ve been interested in building a mostly or completely underground dwelling for some years now, but the price of containers and hauling them to the site has been prohibitive.
I’ve got 5 wooded acres to use to bury them on and (possibly) connect to my existing 12X60 mobile. Was thinking of something like an iceberg, with only the mobile above ground but with one or two containers underground and connected to it. Been planning a lot in the head but not done much of getting it down on paper yet.
My plans have been in two possible directions.
1 - build a house where 80% is underground and the remaining 20% is above ground (basically a two story structure with the second story above ground level).
2 - a buried structure built around a central sunken, lanscaped courtyard. Almost all the windows face the courtyard.
