I think that maybe the significance is that 9 in a significant number in Feng Shui. For example, Marie says that when we do our changes and put our activations in place we should see the results in 9 minutes, 9 hours, 9 days, 9 weeks, or 9 months. It just always kind of figures out that way. I´m not sure about the reason why, but I do remember her saying that it was important. I hope that helps. As regards the two storey house, I´m sorry, I have no idea.
