You build banks on minecraft the same way you would build any other structure. First, gather the materials you need. Then, select the material you want to use for building and right click on a place on the ground to place a block. Place the blocks in the shape of a bank, and you're done. You may want to include other structures in the bank like iron bars, a counter, or perhaps an iron safe.
