The garden that was in place when we moved-in was a raised bed, but it was 30ft by 71/2ft. I really wanted to change it so there would be no need to step on the garden soil, so there would be no compacting. I had to remove the railroad ties, which was not as hard as I was anticipating. Thankfully my dad gave me many lessons on how to move heavy objects, so no back pain, ha :) I am planning on making 5 4'x8' raised beds out of 2x10's or a combination of 2x4's, 2x6's and 2x8's to reach the desired height. The bed closest to the garden shed will be a Cold Frame doubling for hardening off seedlings!
