I am in the south and the latest round of tornadoes came awful close to me. In the past three months there have been three tornadoes, all within 1-2 hours of me. I am in an area that is not known for a lot of tornadoes, but I am also right on the border for hurricane strength winds. I am in a doublewide home, no basement and no storm shelter. I have been searching for days for an affordable shelter, but they are all out of my price range. If I could afford a well built house I would have one, but for now this is my home. I would like to know (with pictures if possible) if anyone has a shelter that they built. I would like to build a shelter that you can walk into, and have it mounded with dirt around the outside. My neighbor is elderly and would have a hard time with stairs, so I am trying to find plans for a walk-in shelter. Ideally, I would like one that is half buried in the ground, with a ramp down to the entry door. This would give us added protection of being partially underground while still being able to avoid steps. Any advice?
