I build a 4'x4' angle iron frame with 11/2" pipe legs. I like them 15' tall. I build a plywood box to bolt on to frame. I stand up with wench. I tie it off to trees on two sides to keep it from blowing over. I have a metal roof, build windows that fold up. They have glass in them to keep you from freezing your ass off when it's cold. I have a heater in each stand also. If I had someone with me in stand a lot I'd build 4'x6'. I like 4x4 because you can see better. Metal frame is much sturdier than wood. I have some that are 35 years old. I can't imagine building out of wood.
