The problem of not going below the frostline in soggy ground is that you may get a lot of heaving of your floor & foundation from the freeze/thaw cycles. Even if you have good water proofing, your building essentially becomes a boat floating in the water table..... Consider building less deep, but earth-berming, effectively making it deeper.
Here in WI, our frost line is 66 inches. It makes the the benefits of building a root cellar cost prohibitive when potatoes only cost 50c/lb in the store. I just keep 'em in the garage heated to `~60deg over winter. They do fine that way, but start to sprout late Feb/ early Mar. Not a problem.
