On many survival sites there is a recurring question about using shipping containers as a shelter at a bug out location. Many of us who have spent time in the sandbox are very familiar with living in modified shipping containers, often called CHUs (Containerized Housing Unit).
Here on KAIA the place we drop off our dirty laundry is constructed from 2 containers welded together, insulated and finished and with a short roof added. This is set on paving stones. If I were doing this in my native N. Alabama I would raise it on poured concrete pilings and the roof would be raised about 3′ above the containers, allowing breezes to play both above and below and keeping sun from striking it directly. A small genny or solar/battery system to run a fan, propane and wood stoves for cooking, kerosene and candles for light. I would probably cook outside in summer. A wrap-around porch and rain-water collection system with propane or wood water heater to finish.
I need to see about running up a budget for such a structure.
