A "do it yourself" burglar-resistent safe is provided at extremely low cost. The present apparatus and method make it possible and practical for almost any person, even a person having a low degree of manual skill and even a low intelligence, to construct his or her own safe with precision. In a preferred embodiment, a plastic liner is precision saw-cut or molded at the factory to provide various slots or grooves adapted to receive the inner edge portions of steel bars having predetermined sizes. The customer purchases the liner and bars in unassembled condition, together with a bottom, a firecap mold, and a strong steel door with associated lock. At any desired region of his home, the customer provides form means sufficiently large to receive the liner and having as much capacity as the customer wishes. Then, the customer inserts the bars into the factory-made slots so as to precisely locate the bars, closes the bottom at the end of the liner, introduces the liner into the form, pours concrete around the liner, and the safe is completed. Major portions of the bars are embedded in the concrete and thus cannot be removed. There is also provided a simple and economical, but highly effective, relocking means.
