According to the traditional concept, leaving three holes in the outer wall of someone else's house may have some influence on your Feng Shui. In Feng Shui, certain shapes, orientations and colors in the environment will have an impact on people's fortune. If the hole in the neighbor's wall is facing your door or window, it may form a bad feng shui pattern such as "through the heart" or "flying sideways", which may affect your family's wealth, health and family relationship.
However, the effectiveness of geomantic omen depends largely on personal beliefs and concepts. If you don't believe in Feng Shui, then these holes in the wall may have no practical impact on your life.
In a word, the influence of wall holes on home feng shui is relative, not absolute. If you are worried about this problem, you can consider placing some barriers in front of your door or window, such as screens and curtains, to resolve the possible adverse feng shui effects.
