Measuring a House’s Facing Direction
What is the facing direction of a property? It is the direction perpendicular (or at 90 degrees) to the facade wall of the facing side of the property as shown in the diagram.
A common questions that I get is whether we should measure looking into or out of the house? Since it is the facing direction of the house, you should use the house as the principal (or host) and measure looking out of the house.
So far so good. But where should we take the measurement?
Logically it should be at the intersection of the the facing direction with the facade wall on the facing side. While it is logically so, it is not the best position to take the measurement. Let me explain why?
The direction of the needle of the magnetic compass can be easily affected by nearby metal objects. You can easily verify this by bring a metal object near the compass.
Most homes here are built using the RC (reinforce concrete) method. Within the beams and pillars are steel bars which can affect the reading on a compass.
For an accurate reading you should be as far away as possible from metal objects. Try to stay away from the gate which is usually made of metal or has a large metal content. It is a good practice to remove the cars from the garage as they may compromise the reading.
So where so you take the measurements?
I will illustrate with a diagram of a typical link house. I would normally take a reading at point A and at point B. Both the position are as far away as possible from the porch pillars, overhead beams, stairs and columns.
In the accompanying diagram, I have indicated imaginary lines that are parallel to the facade wall at the facing. In most homes, these lines are can be real and they are usually form by the tiles or stones that owners install on the porch. In its absence we can use our best judgement and in the worst case scenario, you have to mark it with a chalk.
Usually the reading at both the locations will the same or very close. When measuring the facing direction most system of Feng Shui measure by spans. For example S2 facing is between 172.5 to 187.5 degrees. Therefore if one reading is 181 and the other 182, it is still S2!
Another things that I have observed is the influence of the electricity meter and distribution box. The compass needle vibrates ever so slightly when you are near them. This vibration is almost never seen in buildings that have yet to receive they power supply.
Therefore, I would also advice against taking the measurements too close to them.
Do you need a Feng Shui Lou Pan (compass) to get an accurate reading? Not really but it would be good to have one as the straight edge allows you to easily align with the facing.
A navigation compass with a straight edge will do to. I do not recommend a round compass as as you cannot easily align it parallel to a straight wall or line as it does not have a flat side.
