When you are planning to build your house, the best way is to include a Feng Shui consultation from the beginning, at the time of the floorplans study of the property. You will then benefit from the best configurations offered by the place, to the best ways for the Qi to attract prosperity and of course, how to give you the best wellbeing.
Classical Feng Shui can guide you at the first stages in indicating the good places for the stairs, chimneys, bathrooms. These elements, when wrongly placed can bring disharmony in the family. What is easy to place at the time of the construction, will become nearly impossible once the house is finished.
