Here are pics of my solid fuel storage facility, AKA woodshed and coal bin.
I built the woodshed two or three years ago when I finally got tired of digging frozen wood out of the snow. When I decided to start burning some coal this year, I opted to be a girlie man and forgo the whole "dig frozen coal out of the snow" scenario, so I built a bin. Most of it was built from stuff I had laying around, so I've only got about $150 in it. The walls are old concrete forms I had built to do the rock/concrete foundation on an addition; the siding is rough 1x6's with a bevel sawn on them, I mixed the concrete for the floor, etc. It's 5x10, 6' high in the front, 6' wide doorway, 4' of removable 2x6's, the little doors swing open for shoveling more coal in, shovel it out through the little opening at the bottom. It's working pretty good so far.
