I've built 2 root cellars for people, made from old freight shipping containers.
They come in 10, 12, 20 and 40 foot lengths, 8 ft wide.
I strongly suggest they be buried above the local water table -or they will usually end up underground swimming pools. Adequate drainage will prevent that.
I built mine from an old insulated refrigerator railcar (10 x 50)... the bottom of this link shows a construction picture of how it was covered by digging 2 handy ponds along each side: http://www.preparedsociety.com/forum/f43/maine-iac-4985/
The ponds sure help the gardens in dry summer weather!
We keep all our canning jars and other supplies in it, it stays between 40 and 65 degrees all year round. In the autumn, all the squash and root crops are stored in it, most last till March or later.
... and, you never know about a bad storm or nuclear accident (or worse) in the future, this makes an excellent shelter because of the 24" minimum clay-loam cover over the top.
