Well, I guess that's sort of an "individual needs" type of question. For me, at 51, the kids are grown, two have families of their own, and two grandmonkeys as well and we all live in the same general area (for now). So, what I'm looking for is sort of a "part-time" retreat that will allow me and mine to augment our daily subsistance in the "big city" <grin> of Birmingham, AL by growing various foods and raising a meat animal on maybe a weekend warrior type basis, BUT, also be a viable "sho nuff'" survival stand for whatever comes down the road. I plan on being more "out of sight" than a fortified bunker style, so something I can haul in and build myself with the least number of people knowing about it is my plan. And I didn't have to look any further than Home Depot for my answer. My choice is one of their two story utility buildings. When I started looking at them several years ago, they were in the neighborhood of $6k, now they price out around $8k, and I want to do what is common building technique for my Northern Brothers and use 2x6/10's instead of 2x4's and add the extra insulation and a few more mods so I may have around $10k in mine, but hey, your hard pressed to find a home that will feed ya, house ya, heat and cool ya anywhere in this country (even Alabama) for $10k.
In the beginning, gonna go with enough fold down bunks to sleep everybody in the family if push comes to shove, but would eventually like to have a total of 5 identical dwellings arranged in a circle so that each of the kids and their loved ones had their own. Time is important, and this way we can not only work on the dwelling on the weekends, but get the ground work done for the gardens and such while having a good old family campout to boot.
