Hiya cryptojoe, Good eyes! :o) NFPA regulations don't apply strigently here in Thailand, unless the client is an American corporate entity. The building code and fire code here allow up to 1.80M total riser height (about 10 steps per run) in structures classified for low density residential occupancy. Commercial use structures allow for less (1.40M vertical rise max, I think). I had fun modeling the continuous handrail required by fire code. Never realized what a pain that was to get right till I actually tried it. Cheers! M
