Shipping container house builders are the rectangular metal boxes that are transported on truck beds and loaded onto ships. They are usually 20 or 40 feet long, eight meters wide and about 8 meters high. Some are chilled and can be adapted for air-conditioned living rooms. Transport containers are easy to find and are generally inexpensive. A container is large enough for a temporary bunker to provide protection against extreme weather. Multiple containers can be stacked, indicate beginning to end.
Check your local building codes before you begin, if there are special requirements for your location. Then dig a hole that is at least 10 meters deep and the length and width of your shipping container house. Level the bottom of the hole. Use a tap to place the container in the hole. Cut a door in the ceiling of the bunker to use as an entry. Hinge the part of the container that you are removing and connect it to the ceiling to use as a door. Attach a gasket around the door to cover sharp edges and create a waterproof seal. Use a ladder or spiral staircase to sink.
Provide ventilation for the shipping container house design by cutting holes in the ceiling and mounting them with pipes that will extend above ground level. If you have questions that your piles will discover, plant shrubs around the vents or use other natural camouflage. Cover the container with dirt and fill in all open areas on the sides. Create a catch basin next to the bunker by digging a pond and running a tube under the ground from the basin to the shelters. Attach a valve to the end that is inside the bunker so that the water can be controlled.
