Looking at the house from the front (front), if the wall on the left is high and the wall on the right is low, you can judge that it is a house facing west. Because the sun rises in the east and gradually moves west. In the morning and at noon, the sun will shine on the right wall of the house, making it brighter. In the afternoon and evening, the sun will shine on the left wall of the house, making it look taller.
The height of the house on the left and the height of the house on the right are not only related to the west, but also may be influenced by other factors, such as topography, architectural style, personal preferences and so on. Therefore, it is impossible to determine the orientation of the house only by describing the left height and right height of the house. Reliable methods to accurately determine the orientation of a house include using a compass, GPS positioning equipment or consulting professional architects or real estate developers to obtain relevant information.
