My husband and I got plans from Lowes.com, however a quick search in Google for "compost bin plans" will yield a good number of sources for plans. For our compost bin, we had to make a few substitutions as some of the materials were not available in our rural town. That's the beauty of building your own projects, you can build them in a manner that suites you best. Who says you have to follow the rules! I liked this design because of the removable slats in the front for easier access with a shovel.
