First, the ratio of width to depth
Depth: The width between the north and south walls of the house determines the number of rooms that can be accommodated in the same area, and the shorter the better.
Area width: the width between the east and west walls of the house determines how many halls facing south can be there. The bigger the room, the better.
The golden ratio of width to depth is 4:6.
Second, the building spacing
Building spacing is the distance between the outer walls of two adjacent buildings. The greater the distance, the better. The space between buildings is too dense, which seriously affects the lighting and ventilation of the ground floor. Generally speaking, ordinary residential areas can be calculated by the ratio of building height to building spacing = 1: 1.2. According to the national regulations, the sunshine time from winter to day is not less than 1 hour (the window at the bottom of the house).
It should be reminded that the sand table models of many real estates do not show the actual building spacing, or use light and shadow to create an illusion, which requires detailed consultation.
Third, pool area and house price.
The pool area has been explained in detail before. Look: when I closed the house, I found that the house was small 10 square meter, which turned out to be the fault of the pool area!
The higher the room rate, the better, but the pool area should not be too small, which will affect the living comfort, such as narrow elevator space, dark and narrow corridor and so on.
Generally speaking, the rate of multi-storey houses is above 80%, and the allocation coefficient is between 0. 1 1 ~ 0. 16. The higher the floor, the lower the occupancy rate. The occupancy rate of high-rise buildings is about 70%, and the allocation coefficient is generally between 0. 18-0.26.
Fourth, the floor area ratio
The so-called floor area ratio refers to the ratio of the total construction area above ground to the land area of a residential area. It is directly related to the living comfort, and the lower the floor area ratio, the higher the comfort.
Generally speaking, in a good residential area, the plot ratio of high-rise residential buildings is not more than 5, that of multi-storey residential buildings is not more than 3, and that of green space is not less than 30%.
V. Height and clear height
Height is the vertical distance between upper and lower floors or between floors and the ground, which is the height of the building. The difference between floor height and floor thickness or structural layer height is called clear height. The height of general residential buildings is about 2.8 meters, which can save energy to the maximum extent on the basis of ensuring living comfort.
Generally speaking, the height of the floor is written in the contract, and the indoor clear height is measured at the time of acceptance, ignoring the thickness of the floor, which leads to misunderstanding. The floor thickness of commercial housing is generally 12 cm to 15 cm, so as to judge whether the height of the house conforms to the contract.
Sixth, the proportion of parking spaces
At present, most residential areas, including well-known real estate, can't keep up with parking spaces. If you don't want to grab the parking space after work, please make it clear when you buy it. The parking space in the community should be at least 1: 1, and make a field investigation to see if it is true.
