Partner in Thirteenth Floor Daniel McCullough, right, partner Greg Salyers, center, and builder Victor F. Morales, left, look at the drawings for a piece at the Thirteenth Floor production house in East San Antonio on Thursday, October 1, 2015. The team is working on a mausoleum based on the Dexter Mausoleum in Ohio that they will take to the International Association of Amusement Parks expo in Orlando this November. The Thirteenth Floor Entertainment Group generally produces 8 to 10 pieces a year, primarily for in-house uses at their haunted houses and great room escape locations throughout the U.S. Each haunted house boasts different attractions and all of the pieces from sculptures to entire structures are built in their production facility.
