How about pallets i use them they seem to work good and they have a eery look at night to them!!
I agree. I think one of the best cheap materials are pallets. You can get them for free and some of them are very sturdy, especially the ones for concrete and such. Stack them one on the other and form walls like that. You might have to run a couple of braces along the top. I have a barn that I have turned into a permanant haunted house. I use 2- 4x4 pallets stacked on top of each other for alot of the walls. I also use walls that are framed 4x8 plywood covered. I personally love the look of pallets. The first year I only had pallet walls and I made a maze out of 244 of them inside the barn. I started building it at the end of Sept. so I didn't have time to decorate. So that year I just let it be a maze.
The pallets looked almost like the barn walls. So with a little fog and the right lighting it was very creepy and way too confusing. I thought I was NEVER going to get people through it. Because of the way they functioned I started building all my walls 4x8. Almost everything inside is built divisible by that dimension. That way I can completely change the layout with just a few minor adjustments to the walls. I like it to be rerouted every year. And I can turn an area into room in no time.
Here's the plan this year. It's a little confusing to look at because the upper right is exterior. When you're inside it it looks like you're still in the barn but you're actually outside. We had to do it this way because of the exhaust from the chainsaw. Most of my walls are wood painted to look like stone etc. now, but pallets are the best in a pinch. If you don't like the look of them, cover the wall with black plastic. It works great.
