Looks great design wise, but gonna be pricey to build that roof waterfall. Your gonna need to come up thru the columns with piping amd have a thick enough fascia to insert either sheer descents or a custom spray bar in it. You need multiple water feeds for that length of falls.
good we are in the design process, if it gets too pricey we can deal without it, we got a bid already on everything except the roof top waterfall, waiting to hear what that upgrade will cost, if it gets too pricey we can deal without it.. ... i believe the water fall is only like 6 ft... The builder has done this before, his pool is amazing on a much larger scale...
