The main factors that should be considered in the selection of the floor to buy a house are: the total number of floors of the residential building, the difficulty of escape, the convenience of life, the age composition and health status of the family population, the ventilation and lighting conditions of the residential building, the difference in floor prices and other factors.

Low rise residence: refers to the residence with one to three floors.

Advantages of floor selection: the lower floor is very convenient for families with children and the elderly. When accidents happen, such as earthquake, collapse, fire and other accidents, the lower floors are most conducive to escape. Low price and high space utilization rate: developers generally design the space flexibly on this floor. For example, the first floor has basement, garden, garage and other spaces, and the other floors have terraces, sunshine rooms, patios and other layouts. These spaces are often half sold, half given away, and buyers can get more room space for a small amount of money.

Multi storey residence: refers to the residence with four to six floors.

Advantages of floor selection: good safety performance, convenient for family travel, and moderate floor price.

Medium and high rise residence: refers to the residence with seven to nine floors.

Advantages of floor selection: relatively close to the ground, people and scenery can be seen on the ground, comfort, convenience and space scale are better than those of high-rise buildings, and ventilation, lighting and sunshine can basically meet the living needs.

High rise residence: refers to the residence with ten floors or more.

Advantages of floor selection: good ventilation and lighting. The area has a clear view from the window on the network in the room. High rise floors above 20 have good privacy and can not be disturbed by the surrounding environment. The high-rise has a wide view and good lighting effect. Living in the high-rise and opening the window to see the scenery, you can have a panoramic view of the scenery in the distance. It has the feeling that high-rise buildings can enjoy the scenery, which adds a bit of life interest and taste, greatly meets the needs of people's home landscape, fully reflects the humanistic concept of modern housing, and brings the residents a sense of achievement.

Top floor and ground floor

Many buyers are reluctant to choose the top floor and the bottom floor, because the top floor is hot in summer, and it is not suitable for living if the developer does not do thermal insulation treatment. The bottom layer is vulnerable to mosquito attack and has heavy moisture. However, the top floor and bottom floor are affordable in terms of price. Buyers with ordinary family economy can consider these floors.

The most important thing to choose the top floor is to see whether the developer has done thermal insulation treatment. Many top floors buy the top floor and send it to the attic, so this kind of house is very economical.

The moisture-proof design and measures shall be carefully checked before purchasing the bottom layer. The moisture-proof measures are not up to standard. If you live in such a house for a long time, not only the electrical appliances and furniture are prone to rust and mildew, but also people are prone to rheumatoid arthritis. Secondly, pay attention to whether all kinds of pipelines are unblocked. Because the bottom layer is adjacent to all kinds of pipelines, especially sewers, if the quality of the pipeline is poor or the design is unreasonable, the pipeline is easy to be blocked, especially if the septic tank is not tightly closed and the pipeline is not smooth, it is also easy to breed mosquitoes and flies and the odor is high. Thirdly, pay attention to the lighting problem. The ground floor is located at the bottom of the building, surrounded by many buildings, so its lighting and ventilation are often limited.

As a whole, the selection of high-rise residential floors can be made according to the rule that "residential buildings with more than 1/3 of the total number of floors and less than 2/3 of the total number of floors are better". The selection of different floors in the total number of floors is also different.
