The wider the distance between buildings, the better.
The distance between the front and rear of the house: the distance between the two floors shall not be less than 1.2 times the height of the front building. According to national regulations (design specifications), the winter solstice sunshine time is not less than 1 hour (the bottom window of the house) as the standard. The distance is the height from the building's outdoor flat to the house's cornice/tan(a) a-the sun's altitude angle at noon on the winter solstice.
The distance between the left and right houses: the distance between multi-storey (4-6 floors and below) and multi-storey buildings is 6 meters, the distance between multi-storey and high-rise buildings (12 floors and above) is 9 meters, and the distance between high-rise buildings and high-rise buildings is 9 meters. 13 meters.
Factors affecting the distance between buildings:
1. Lighting: If the distance between buildings is too small, the sunshine time of the house will be too short. Of course, in addition to the darkening of the light in the house, it will also make the temperature in the room lower and more humid.
2. Ventilation: Generally speaking, the larger the distance between buildings, the better the ventilation conditions will undoubtedly be. Because a good living environment must not only ensure adequate lighting, but also have good ventilation performance.
3. Noise: If the distance between two buildings is too small, the sounds of pedestrians and vehicles passing between the two floors will be clearly transmitted into the house. What's more, the noise from the residents opposite will also be transmitted here.
4. Safety: The problem of internal traffic congestion caused by too narrow building spacing cannot be ignored, especially now that many residential areas have insufficient parking spaces, and owners will occupy the traffic lanes when parking. If the distance between buildings is too small and there are too many private cars parked on the roadside, when a fire breaks out in the community, it is very likely that fire trucks will not be able to drive through.
