I built a couple elevated platforms for the Maverick six shooter blinds, one at 4' and the other at 8'. The 4' blind is for my wife and my FIL for rifle hunting, I went with the Maverick because you can also bow hunt out of this pretty easy. The 4X4 leg brackets were made by a local dock builder and worked great. The platforms are 6'X 8' and 4' and 8' tall all treated wood. I know someone will see the joists on the 8' platform and yes there will be 3 more added along with cross bracing, I wanted it a little lighter because of lack of help lifting. The 8 footer isn't put out yet. In place.
