RE: permanent blind suggestions
You will need at least a 4' x 6' area if more than one is going to be in the stand at one time. I built 4' x 6' platforms and then a 4' x 4' x 7' plywood box on top. Leaves a 2' " porch" ...a safety issue upon entering and leaving the stand. Cut windows in side as needed and then cut plexiglass windows for openings. Carpet floor, Buy a heater, swivel boat seatand your set. Stands are approx. 8' off the ground ...so steps work great for entry.
