It seems to be Teak, which is a quite expensive wood. Lots of Yachts and Boats are made of Teak and it is used widely on decks, so, I still dont understand what your question is? What you are saying, is that because of the electrical and AC Vent, you need to drop the ceiling? Do you have straight walls/ceiling? can the wood be attached to the existing ceiling?

You don't need such a large double height ceiling for a small house, half of that size will do or remove it completely since you do have setbacks. You can remove the bedroom balcony and pantry which will end by being underutilized. Move bedroom toilet to where the balcony is or where the wardrobe is. Convert the family room to another bedroom. The double height space and current toilet of M. bed would then be your family hall
