Do you need a screen wall at the entrance of the rural north house facing west?
In some geomantic beliefs, the main function of the shadow wall is to block the airflow directly entering the house from the gate and avoid forming a straight airflow, thus affecting the gas field in the house and the fortune of the occupants. According to this view, if the gate is opposite to the center of the house gate, it is necessary to build a shadow wall to prevent Yin Qi from directly entering the house.
But whether you need a screen wall depends on local specific conditions and beliefs. In some areas, people may not mind that the gate is opposite to the house gate, or they may think that the shadow wall will bring other negative effects.
In addition, the screen wall has other geomantic significance, for example, it can improve the privacy of the house and reduce noise. Therefore, you may need to consider these factors and other local customs and beliefs when deciding whether you need a screen wall. If you are in doubt about this, it may be more helpful to seek advice from local feng shui masters or professionals.
