>>1287207The issue with these "dedicated solutions" is that they're largely designed to be used only in emergencies, rather than as a permanent living solution. Granted, 50K for an underground shelter might be at least competitive pricing versus a house, depending where you live. The long-term costs people seem to talk about is having to replace a shitty shower system (the one they built into the thing) in a metal culvert that's 20 feet underground, and the new shower probably can't clear the four square feet of manhole to get into the shelter in the first place.
As for me, I'm looking for a permanent living solution. I've got the 30 acres of land already, regardless of what I put on it. I'm single and have no family moving with me, so living in a metal building isn't going to bruise my pride, what with all of four neighbors within five square miles of my property.
As best as I can tell, this type of metal building is relatively inexpensive to buy and doesn't require any special skillset to construct.
As recently as 2017, some guy on YouTube did exactly what I am describing (albeit without burying it), and his numbers were "two tons of rebar" (I am supposing about 3,000 feet or at most $2000 worth based on some offhand calculations) and 40 cubic yards of concrete ($4000 at most, offhand). Then for a metal building, I'll suppose I could have one built for $20,000 (admittedly a bit of an overestimation for a 30 x 40). That's $26,000 (not including labor, though I am confident in saying that I can do it all myself and a little help from my friends, with the sole exception of applying shotcrete) for a considerably bigger living area than the $50,000 shelter I'd otherwise buy. At this point I am out-competing the cost of buying or building a house.
As for integrating my abomination into a hillside, that will take about 60 cubic yards of dirt, or, less than $1000.
But will my structure support that weight? This is where my knowledge runs out.
