Our safe houses are build to be maintenance free, off the grid, impenetrable, and cost effective. They are build with steel plate to cover and lock all windows. The roof is equipped with solar power and water capturing devices that funnel the water into a holding tank. Every safe house is wind and water tight meaning that it is impossible for any mice or snakes or ants to enter the unit and disturb your stored food. The container itself is also made out of Cor-Ten steel which can not rust so once set into place this unit will never need any maintenance or repairs.
