Eight Mansions is also known as the 8 House approach in Feng Shui and is based upon space dimension of a dwelling. This is one of the most popular formulas used in Feng Shui as it determines good and bad locations in a home or office, whether a resident is compatible with their house, finds lucky and unlucky directions and how to enhance and naturalize the affects of these directions.

Each dwelling in question is divided into eight sectors that correspond to the eight magnetic compass directions ie: North, South, East, West, Northeast, Southeast, Southwest and Northwest. From this analysis the practitioner will be able to locate the sitting and facing direction of each residence. Each house is then classified into two further groups (East Four or West Four Group) purely based upon its sitting direction.

Then the formula requires the practitioner to calculate a Kua number from each individual’s birth date and gender. This will ascertain his or her four auspicious and inauspicious locations/directions based on the eight magnetic directions of a compass. Each direction is 45 degrees in angle and possesses different types of energy that will influence the sector and the person residing there in regard to their kua number.

Once this is calculated and the dwelling is mapped out with the 8 compass directions, the next step is to ensure that each individual is utilizing their good locations not their bad and are facing their lucky directions not their unlucky directions.

The practitioner will try and ensure that important rooms such as dining, living, family, study and bedroom are all located in good locations. However, areas such as toilets, kitchens and maids room should be situated in the bad locations in a dwelling. They will also ensure that you are sleeping, eating and working in auspicious directions.

As 8 Mansions is based primarily upon space, compass directions and Kua numbers an experienced practitioner may also suggest the Flying Star Formula as it incorporate time dimensions.
