I am building a raised bed using concrete wall blocks. They have a small lip on the back edge so each brick grabs the block below it. It helps to dig in the first row of brick a couple inches into the soil to hold that row in place. Then build on top, staggering each brick so they aren't sitting squarely on top of the one below. It will look like this when its done but not so tall.

The bricks come in all sizes - I chose small ones that I could easily pick up and build with by myself.
Spray the sod with roundup and build away. If you make your raised bed over a foot deep, whatever grass is left will be discouraged from growing that far. Unless you have burmuda or crabgrass....
