In the past, I have discussed several different situations where relocating from the relative security and comfort of home might be useful or needed for your ongoing safety and well-being. I don't live in an especially rugged house, but it's what we can afford, and it's in a very good neighborhood. House-hopping to one our better equipped neighboring properties is an option we've discussed, in the event of a bug-in situation in a fall of society type event. I've also covered some of the strategies and philosophies regarding sheltering from fall-out and CNBR type events. Given where I live is rather close to the Port Phillip Bay, sea level rise and storm surge type events are a more likely type of natural event that would cause us to bug-out. I've investigated the suitability of a self-storage facility as a quiet, out of the way place to dig-in, and even discussed the relative security of major infrastructure facilities like a hospital.
But today, I'm going to discuss the relative utility and safety of bugging out to another kind of location, dear to my The main showroom, with its labyrinth of lounge rooms, kitchens and bedrooms is situated on the second level, at my local Ikea, which is itself two stories up, above a dual-layer car-park. The warehouse starts our under the showroom, but also runs beside it, and stretches three to four stories up. Stairwells and escalators give main entrance to the facilities, as well as lift wells, but the broad concrete construction is fairly stark. Exits are clearly marked, as per whatever construction codes that must be adhered to, but I also noted that there not too many "other ways in". heart. Ikea!
There is loot, so much loot. Essentially, whole houses can be fitted out by what is in stock at Ikea, so as far as establishing a livable space, there is so much to choose from, and room to do so. Big spaces are hard to heat however, and leaks in the roof could make for a lot of cold wet concrete flooring on exposed levels.Being raised up two floors from ground level gives you a lot of clearance for the "livable" areas, assuming you don't have tectonic collapse to worry about. Lots of concrete and little to no fuel (other than stock) in the construction means it is pretty fireproof.
It's not inconceivable to me that an Ikea could be converted into a reasonably livable village for a small community. It's not a fort, by a long shot, but it is a stocked piece of real-estate, and even comes with more than just Allen keys, these days. A small restaurant and deli section offer only limited edibles, and there are only limited spaces for indoor crop growing, but plenty of materials for glasshouses.Remember that other people might have the same idea, however, and might not want to share.
Something to consider when you are next at a big center like this; look around, check the exits, look for structural flaws and the resources on hand ... You never know where or when you might need to hole up...
