Wood, steel, stone - choices, choices...

Having put together my initial design based on a timber frame with block walls I have had a few thoughts about redesign myself and been given a few pointers from some local experts that now have me in a bit of a quandary. I've decided to go for smaller, slightly higher horizontal windows on the basis of safety, as the dojo is about 3 floors up, and reducing unnecessary costs where I can. So that will mean a bit more blockwork than before. I'm also thinking about incorporating in some skylights if possible to let more natural light in. But the big question is whether a timber frame will be typhoon proof. My builder says he would use a steel frame due to the length of the beams. He definitely knows his stuff when it comes to construction but I also know that he will often present his preferred option (based on time, cost, hassle, the skills available, etc) as the only option. So do I go with my gut instinct which is to build with timber, a natural beautiful material that I can work with easily, or the steel frame option?? I have to decide this before anything can move forward...
