I wouldn't throw this out as one to copy but it has worked OK.6'x6'x6'.The windows are something like 16"x48" and each has 4 plywood sliders so that you can close them completely or customize shooting or peeking openings.There is a door in the back and it has a drop down hatch for viewing.The window sill are app 32" off the ground.You have to sit or kneel to shoot.To shoot standing,I think you would need at least 7 1/2' height.The window sliders rattle in the wind so next time,I'd come up with something else but the animals are used to that and pay little attention.
That hay bale is there to keep the wind from taking the shack.It actually rolled and destroyed the last one beyond repair and they weigh several hundred pounds.It gets windy here.
Every corner has a 2x2 and they are also placed every 16",like studs and they are also around the widows and door.Everything is screwed together.
You can see the shack over my shoulder.The closest shot so far has been 8 yds.
