Built a few of these over the years, went to a shorter shooting house due to the wind blowing them over ! The color pic is of a 10' stand , we've also built a 12' one & it's just right for gun hunting. Went to junk yard & got an old school bus seat to put in them & they work great & will hold 2 people . The shooting rail height Above floor is by personal preference , typically 36"-40", mine is at 40" & works for me , but for kids 36" works better. We used P.T. plywood but you can save appx.$ 75. if you use untreated plywood & paint it.
