This is a scale model, so it stands 8'x 8'. The actual size of it was 16' x 16'. Drill two holes on the sides of the plywood that will be standing upright. Drill three large holes in the top piece of plywood evenly spaced out.
Place brackets over screw holes.
Insert screws through metal brackets. Place a washer on the screw, then tighten it with a wing nut. Put structure together after tying rope through the large holes in the top of the plywood. Watch structure very carefully so that no one hangs themselves.
