The house is on the fifth floor, and the trees are six stories high, so the lighting is definitely not good, because the south direction is the main direction of lighting in China. If the balcony is next to the bedroom, the bedroom will have poor lighting, and then it will consume more energy, such as turning on the lights often and heating in winter.
If the south building is still a building, it depends on the height of the building. According to national standards, the building spacing is not less than 2 times of the building height (Beijing is 65438+ 0.5 times of the building height). That is to say, if it is a six-story board building, the height of one building is 15 meters according to the height of each floor, so the distance between two buildings should not be less than 30 meters, so that the lighting will not be affected. Similarly, if there is no building in front of the building but only a mountain, and the mountain is more than 200 meters, it will also affect the lighting.
When it comes to geomantic omen, I have probably seen the saying that the back of the mountain faces the water before, so if the entrance of the building faces north, it is considered as the back of the mountain, and geomantic omen is ok, but if the entrance of the building faces south, it seems that there is a similar saying, and the future is blocked. However, I think it probably means that there is a mountain in front of the door. Being too close will affect ventilation and lighting.
