This is the homemade haunted house that my friends and I made this year. The entire build was in my friend's large basement. We recycled props from the past couple years, and even made a few new ones. If you're wondering, the walls are 4Mil Plastic Sheeting that we bought at Lowes. I believe the final count was 12 or 13 rolls of 10ft x 25ft sheeting. This is a semi-expensive hobby to do every year.
The videos below include the building of the haunted house, the first walkthrough before any major changes are made, and then two videos of the guests reactions.
It just goes to show that with a little bit of creativity, a little bit of money, and a lot of great party guests, you're guaranteed to have a great Halloween party.
