First off I know I have way to much time on my hands.
Was reading and came across several people that prefer a larger blind (such as a 6x6, 4x8, 5,7 etc.) so started brainstorming. 32" wide sides on an octagonal pattern gives just over 6'-5" outside to outside walls. This should eliminate any possible blind or dead corners. The walls I figured a way to still use only (5) sheets which is what I used on the 4x6 layout. Flooring is a little trickier as it will be pieced. Framing members might require a few more pieces but those are normally cheaper parts. I rip a 2x4 with a 22.5 degree cut to get the vertical corner pieces.
No floor or roof bracing added at this time.
This would be a little more tedious to build but once done might be a nice blind.
