Great post!!! I hope to build a 4ft by 6ft box this summer. The sides and roof will be metal, since I had some left over from my shop build. We only build them about 15 inches off the ground. Also, we open our window holes to the inside, but I like the way the open to the outside on the one. Also like the sliding boards you did. Vey nice. Keep us updated please, I hope to have pictures of mine before hunting season.
