The Triangular Grid System: Designing Outside the Box

Friday, 13 May 2022
11:00 am - 12:00 pm

Your average run of the mill Fright Attraction is designed on a “square” 4' by 4' grid pattern. Boring! However, in this lively cutting edge session, Haunt industry icon Leonard Pickel, will show attendees how to design out of the “box” using the "Triangular Grid System" that he developed over his almost 40 year haunting career. Not just a design pattern, the system utilizes a wall panel design that is easier to construct, lighter, stronger, easier to carry and takes up half the storage space of typical panel construction. The triangular grid itself provides more lineal pathway per square foot than the old "square grid" configuration, stronger structurally and is more disorienting to patrons. In this comprehensive instructional session, attendees will learn the ins and outs of the triangular grid system and its history, designing tips with the triangular grid, panel construction, how to lay out the grid, how to install the wall system, how it passes code, when to use the triangular grid and when not to. the positives and negatives of designing outside the box with the Triangular Grid System versus the average square grid.
