How to Build the Ultimate Compost Bin (Rodale’s Organic Life)
http://www.rodalesorganiclife.com/garden/how-to-build-compost-bin Check the link above for a semi-technical three-bin design that will result in the most hassle-free composting there is. If I had the space for a three-bin system, I'd be on it in an instant. In other words, when you work with large bins, there's much more room for error as opposed to a worm system or composting with a pair of trash cans. The only aspect of this design that I deviate from is the process itself- I don't turn compost at all, so I'd just keep the middle bin full of cover materials, add to the first bin for up to a year using cover materials from the middle bin, then work on the third bin when the first is at capacity.
