I'm in the final design phases of my new post frame woodshop (20x36) and am going with 10' high sidewalls and scissor trusses so the ceiling will go from 10' to approximately 15' in the center (9/12 roof pitch, 7/12 bottom chord pitch). Pleanty of headroom for a woodshop, and if I ever decide to switch gears from woodworking to cars I should be able to put a lift in there.
