If the neighbor's house is built higher than yours, which affects your neighboring rights in terms of traffic, ventilation and lighting, you can ask to stop. Building floors need to be approved by the planning department, and the specific situation can be reflected to the planning department first.
Supplement: Mainly due to customs, superstitions and other reasons. I wonder if there is a law to follow and can it be supported by the law?
I suggest you look at two points: first, whether the "neighboring rights in transportation, ventilation and lighting" are affected. The second is to see how the planning bureau handles it.
Neighboring parties should not demand too much from others, of course, their own traffic, ventilation, lighting, etc. can not be significantly affected. Moderate, forget it. It's too old-fashioned to fight for high and low. Neighbors are more powerful than brothers in taking care of family life and property safety. Harmony between neighbors is much more important than the height of the house.
