Gatorbuck, I built my own about three years ago and it wasn't difficult at all. Mine is 8' wide x 7' tall x 5' deep. It sits two full sized people comfortably, three if one is a kid. Also, I wanted to build it tall enough to where I could stand and stretch. I used reject lumber (Home Depot, Lowes) for my 2x4's and saved money. Mine were pressure treated, as it is a ground blind but it could be elevated. I used OSB sheets for the walls which is starting to peel and I'm replacing it with 3/8" plywood. I've had fun with painting camo patterns, but I have gone with mostly black because of the simplicity. I also painted the inside black to keep an unpainted background from getting me busted. That also keeps light from reflecting inside. I used corrugated tin for the roof and didn't pay too close attention as far as sealing any cracks there. It can get plenty warm here in a closed blind and those drafts can feel nice. Also, I used screws as opposed to nails, (except for the roof) and it is making it easier to replace my OSB walls. Carpet keeps the noise down. Sorry, no written plans, but I would think that the second one would go easier and so on. Total price for it was about $100. Good Luck, I hope this helps.
