UCSF MEDICAL CENTER in San Francisco, California is using the natural plywood panels for the lobby, providing the walls with a clean and natural appearance.  Additionally, natural plywood veneer was also choosen for the doors.  

In this application, the size of the panels and the locations of reveals was carefully considered in the design phase.  Note that  the grain  runs the length of the panel and the core material runs perpendicular.  Keep this in mind in applications   where some of the panels are applied vertical and some horizontal.  Realize that the horizontal panels will need to be cut in half and mitered together to keep the grain running in the same direction.  

Also, during the design phase, consider how the complete wall system will meet the fire rating requirement. Discuss the process of fire rating with the manufacturer prior to specification. As for veneers, many products can be specified for extra tall doors, up to ten feet in height.
