The magnetic meridian should pass through the centre of the plot. While planning the structure, care should be taken that it is parallel to the wall compound. The passing of the magnetic axis through the middle of the plot is good. If the structure is not parallel to the compound wall, it creates difficulties. Therefore, every structure should be parallel to the compound wall.
If the magnetic axis is not parallel to the compound wall, meaning, all important directions are in the corner of the plot, and the structure in spite of being as per proper magnetic meridian and still if the structure is not parallel to the compound wall it is improper. If the magnetic axis is not passing through the center of the center of the plot but lying in a corner of the plot and the structure parallel to the compound wall, advantages and disadvantages are of medium level.
