Step 1
Determine the size of the shelter you wish to build and design it on your paper. Make certain you include a doorway.
-
Step 2
Dig a hole that is a foot deep, making sure it is level and to the total area of your design.
-
Step 3
Measure out the height and width of your shelter and cut the 2 x 4 beams and plywood to match.
-
Step 4
Build three wall frames out of the wood you just cut by nailing one sheet of plywood to the 2 inch thick ends of the 2 x 4 beams for every 1 foot of length of your wall and flip and repeat for the other side. Add end caps to the frames.
-
Step 5
Build your wall with the door in the same manner as the other three walls, but you will have two smaller halves instead of one larger one.
-
Step 6
Create your ceiling frame the same exact way as the walls but leaving one side of plywood off as the ceiling will be made laying flat on the ground.
-
Step 7
Arrange your walls in your hole making sure the frames are flush together.
-
Step 8
Use a mallet and hammer the frames into the dirt about 1 to 2 inches.

-
Step 10
Pour the concrete into your frames filling them to about 1 inch shy of the top.

-
Step 12
Pour concrete into the hole to make a floor and add stabilization to the walls.
-
Step 13
Attach the ropes and pulley to the ceiling piece and hoist up and into place on top of the walls.
-
Step 14
Install the angled brackets with concrete screws where the ceiling meets the walls, two on each corner and two on the seems where the walls connect.
-
Step 15
Measure your finished doorway and have the sheet metal cut to match the height, shy several inches and the width elongated by ten inches.
-
Step 16
Fasten the handles to the sheet metal along with one half of the latching mechanism.
-
Step 17
Install the sliding door track to the ceiling and floor with concrete screws according to the instructions, but so that they are on the inside of the shelter.
