An exhibit structure that incorporates two or more levels, with an upper deck or second story accessible by stairs or a ramp built within the exhibit footprint. Multi-story exhibits create significantly more usable square footage within the assigned booth space and are used for private meeting areas, hospitality spaces, and elevated product display platforms. They are subject to strict engineering requirements, must be stamped by a licensed structural engineer, and require advance approval from show management and the venue before construction can begin.
