What is the proper distance between buildings? Is the wider the better?

The space between buildings is not as wide as possible.

Distance between the front and back of the house: the distance between the two floors is not less than 65438+ 0.2 times the height of the front building. According to the national regulations (design code), the sunshine time from winter solstice shall not be less than 1 hour (window at the bottom of the house). The distance is the height from the outdoor terrace of the building to the eaves of the building /tan(a)a- the solar altitude angle at noon from winter to Sunday.

Left-right spacing of houses: the spacing of multi-storey buildings (4-6 floors and below) is 6m, that of multi-storey buildings and high-rise buildings (12 floors and above) is 9m, and that of high-rise buildings is 13m.

Influencing factors of building spacing:

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 affecting the dark light of the house, it will also make the indoor temperature low and humid.

2. Ventilation: Generally speaking, when the distance between buildings is large, the ventilation conditions are undoubtedly better. Because a good living environment, not only to ensure light, but also good ventilation.

3. Noise: If the distance between two buildings is too small, it will inevitably lead to the sound of pedestrians and vehicles walking between the two floors being clearly transmitted to the house. What's more, the noise of the residents across the street will also spread to this side.

4. Safety: The problem of internal traffic congestion caused by the narrow space between buildings can not be ignored, especially now that the parking spaces in many communities are insufficient, and parking by owners will occupy the driveway. If the distance between buildings is too small, and there are too many private cars parked on the roadside, then when there is a fire in the community, the fire truck is likely to be unable to drive.
