Can the balcony floor be higher than the room floor? How about Feng Shui?

I don't know if feng shui is good. It is definitely not good for the balcony floor to be higher with one hand than indoors. First of all, if the balcony is not closed, the water from the balcony will flow indoors in rainy days. Secondly, there is a height difference from the indoor to the balcony, and you will trip if you are not careful, so it is best to remove this height difference.
