I want to build a firewood storage "pass-through" into a wall near an insert in our living area. I'm not sure I'm calling it the right things so I'll explain a little. I envision basically a small room hanging off the side of my house that is 20" or 40" deep (1 or 2 log lengths), 4' wide and 6' tall. I'd have a door on the outside and inside walls. I'd open the outer door, fill it with wood, and then access the wood for loading the stove from the inside. Sounds pretty simple but I thought I'd ask those that might have already built one for advice: "do"s and "don't"s, etc. Thanks in advance.
