Sorry, the image works now. jdubbya, thanks I was leaning towards the Stiltbeast tutorial for the drop panel. Seems to be simple construction, lightweight and cost effective. As for the walls, I believe I will that same process, 2x2s and the 5mm underlayment to erect the walls. Additional bracing will be required in order for them to stand up, but I don't foresee that as a problem. Since this is an inside haunt, I don't need to beef up the construction to withstand any weather. I'll post images later.
