GOING UNDERGROUND. . . LITERALLY!
Here are some unique and ingenious DIY ways to go underground. Shipping Containers, Quanset Huts, Pre-cast Concrete Culverts, Corrugated Steel Culverts, Grain Silos, Sand Bags, Storage Tanks, as well as Pre-Fab Shelters that run the gamut from efficiency to luxury. There are decommissioned missile silos that have been converted to Luxury Condos, Time Share Units, Co-ops, you name it it's out there.
Security shelters have become a burgeoning industry, not to mention supporting industries like survival gear, Emergency Food Supplies, Firearms, Generators, Solar, Water Filtration, and more.
You'll find Prepper communities whose members share skills and duties, each contributing towards the success of all.
Homesteading, whether above or below ground, in no way resembles the homesteading of our ancestors. We are more advanced, we would still have a lot of our modern technology, and the tools and facilities to fabricate or grow just about anything. Our ancestors didn't have laptops that contained thousands of recipes, complete libraries, how-to and DIY project instructions, modern survival techniques, tactical maneuvers, movies, games, music, and more. Yes, it would be a much different world. I find that the more I delve into this phenomena, the more appealing it sounds.
