With the addition of a wood stove this past year, I figured I needed a place to store some wood. I made these ladder type wood racks that include a roof for keeping off rain and snow. Here is the end result.
This is a picture of the "ladder" style that I built for holding the wood:
Here is a picture of a 16 foot wide, double-bank rack I put up on the side of my house along the fence line. This one is about 5 feet high with horizontal support beams for the 5/8 plywood roof going in both directions.
And here is an 8 foot wide, triple-bank rack that I put out on the back of the property near the rear fence. This one is 6 feet high, again with support beams going both directions for the roof. We are going through wood pretty quickly already so I imagine I will be building another one of these next spring right next to it so we can store more.
