Underground construction is really hard to do correctly. I agree it is harder to do correctly and costs more. It's an investment that if done right could outlast any above ground home. But that is quite a loaded caveat on my part, done right. That's why I envision this being done in a factory and very specific instructions and compliance requirements that if adhered to should produce more predictable results. The bunkers I see people building today are all custom one-off designs and I think that is where they get into trouble. I do like the idea of heat pumps. That would be a balanced trade-off for those that do not want to mess with putting in a home under ground.

>It's an investment that if done right could outlast any above ground home. I would think this was true, but what I've learned so far suggests it's not... Underground, you're not finding refuge from harmful forces on your structure; they exists there too. Things shift, things crack, things leak, humidity causes problems, the whole exterior now endures a chemical interface with the surroundings (and all your Vault-Tec steel will corrode at some speed determined by the nature of the local media). If you're lucky enough to have near-surface bedrock where you are, digging into that is probably your best bet, but, even then, it seems like an uphill battle.
