Deer Stand plans

[M.T. Pockets]

I'm planning on building a free-standing deer stand. I'm hunting a brushy area where tree stand aren't an option. I'm thinking of something simple, made out of 12' 2x4's for legs and a floor about 8' up with plywood around the top 4'.

Has anyone built one that they like ? or would anyone have any advise on how to build one (or what NOT to do when building one).

Thank you.
