Jenny:
Once upon a time I tried to "compost" my leaves by stacking them in a large upright wire cage. Basically a 4' high wire circle made from 2 x 4 wire. In compost terms, they were the carbon. But because I failed to add any nitrogen, they just sat there and did nothing. Over the course of the winter, the only ones that did much were on the bottom. They eventually started to rot down a bit, but the ones on top stayed "crisp" most of the winter. In a wire cage, they tend to shed rain and snow and quickly dry out once the wind hits them.
A 25' roll of 4' 2" x 4" welded wire, or high chicken wire (poultry netting), will make two of these bins, and each will hold about 50 cubic feet of material. If you fill and cover the top with a plastic tarp, plywood, tin roof, etc. to shed the rain, they might keep all winter with no damage done to them.
Also, they do pack down over time due to their own weight. So you can fill them, then come back and add more as time goes by.
If you don't mind the aesthetics, 4 wood pallets wired together at the corners will also work. Being square, they will hold more and if you place them on concrete blocks on the corners, you can dig leaves out from below as needed. Fill em and cover em and they will last a long time.
