This is a very simple example of adding a finish material to the interior of a shipping container's corrugated panel. Shown is a 20' standard container with cargo doors open and an 8'x10' opening cut into one side by the back. The project is somewhere in the outback of Australia. Because of the climate, no insulation is needed between the corrugation and interior paneling. Sun gets very strong, would be a good move to have some shading on the south and east elevations. Without the shading, some ceramic paint on the south and east sides of this shipping container home unit would be advisable to reflect the sun.
