What does floor price difference mean?

Floor price difference refers to the price difference between different floors or floor intervals in a building, which is generally regular. For example, every additional floor or a certain number of floors will increase or decrease the unit price of the house by a certain amount. But this price difference cannot be used as the basis of the actual reference amount. The higher the house, the more expensive or lower it is. According to the height of the house, whether there is an elevator or not, the high-priced range is also different.

What should I pay attention to when buying a house and choosing a floor?

1, where the residential floor is above 12 and below 18, there should be at least 2 elevators, of which 1 must have the function of fire elevator; There should be no less than 3 elevators in a purely residential building with floors above 19 and below 33, and the total number of households serving is between 150 and 270, of which 1 must have the function of fire elevator.

2, understand the floor water supply, water pressure, power supply, emergency power supply and other details. High-rise residential buildings have water tanks on the top floor, so that water is pumped to the top floor and then supplied downwards, so that high-rise residents will not use water because of insufficient pressure; The configuration of emergency generator set is also very important to ensure that the elevator can run safely temporarily in case of power failure.

3, high-rise residential property management can not be ignored, especially monitoring safety measures. Whether there is a guard room on duty on the ground floor of the building, whether there is security patrol in the building, and the safety of evacuation in case of emergency.

4. Pay attention to the total number of households and elevators in the whole building. The quality and running speed of the elevator are also very important. In general, there should be 2 households 1 staircase or 4 households with 2 staircases in the residential buildings with more than 24 floors. At the same time, we should pay attention to the size of the elevator and whether it can be equipped with a stretcher for first aid. If there is a pregnant woman at home, it will be used during childbirth.

5. After confirming the safety of high-rise residential buildings, consider the residential elements such as apartment type, orientation and ventilation. Make yourself comfortable and satisfied.

6, fire power supply. The stairwell, fire elevator room and its antechamber, shared antechamber and refuge floor (room) should be provided with emergency lighting and evacuation indication signs, and the battery can be used as standby power supply, and the continuous power supply time should not be less than 20 minutes; The continuous power supply time of high-rise buildings with a height exceeding 100m should not be less than 30min.

7. It is not advisable to choose a floor that is too high. Generally, fire engines can rise to about 25 meters, and fire monitors can reach about 60 meters long, so water can reach 85 meters high and high energy can reach about 25-26 floors.

8. High-rise residential buildings are generally cheap at both ends and expensive in the middle. The lower the floor, the cheaper the price; The higher the floor, the more expensive it is. After reaching a certain height, the higher the floor, the cheaper the price will be.
