Let’s not talk about traditional Feng Shui. From a modern perspective, there are also the following issues that need to be considered:
The first is lighting. For those with small floor distances, lighting must be Will be affected, especially residents on lower floors.
The second is ventilation. Same as above. Because the distance between the two floors is too close, the ventilation of residents on some floors will be affected. The wind forms a cross wind between the two floors and cannot blow into the room.
The third issue is privacy. If no shield is used, every move in the home will be seen by the upper-floor residents in the adjacent building.
The fourth issue is safety. If you throw something upstairs, it will easily hit the glass.
The fifth is the psychological effect. The space is so small and facing the above problems makes people feel unsafe and depressed.
In short, if you have the conditions, try not to choose the house above. However, if it is really restricted by conditions, such as children going to school, etc., then use decoration to change it. For privacy issues, you can hang curtains or put up transparent stickers. For safety, add safety guardrails, etc.
