How to distinguish between low-level, high-level, small high-level and multi-level

According to the different floors, it can be divided into low floors, multi-floors, small high floors, high floors and super high floors. But many people feel vague about how to distinguish in detail. Today, Bian Xiao will give you a summary.

1 ~3 floors are low-rise residential buildings;

The fourth to sixth floors are multi-storey houses;

The 7 ~ 10 floor is a medium-high-rise residence (also known as a small high-rise residence);

1 1 ~30 floors are high-rise residential buildings;

More than 30 floors (excluding 30 floors) are super high-rise residential buildings.

How to choose the difference between small high-rise and high-rise buildings?

Compared with high-rise buildings, the difference between small high-rise buildings and high-rise buildings mainly lies in the difference in height and number of floors, but the difference between them in floor selection is still great.

Small high-rise buildings have won the love of more buyers because of their convenience and comfort. What floor is the best for 1 1? This is what many buyers want to know. From a height point of view, there is a multi-storey residential atmosphere, but it is also a low high-rise residential, so it is called a small high-rise. For this small high-rise launched by the market, it seems to be a middle road between multi-storey and high-rise.

Characteristics of small high-rise buildings

(1) The floor area ratio of buildings is higher than that of multi-storey houses, which saves land, and the investment cost of real estate developers is lower than that of multi-storey houses.

(2) This kind of small high-rise residential buildings mostly adopt reinforced concrete structure. From the plane layout of building structure, plate structure is mostly used, which has a large design space in terms of apartment type.

(3) Because the elevator is designed, the floor is not very high, which increases the comfort of living. However, due to the limitation of floor area ratio, the price of small and high-rise buildings is generally higher than that of high-rise buildings in the same lot, which requires developers to spend more time on improving quality.

Characteristics of high-rise buildings

Buildings with more than a certain number of stories or heights will become high-rise buildings. The starting height or number of floors of high-rise buildings varies from country to country, and there is no absolutely strict standard. High-rise residential buildings are the product of urbanization and industrial modernization, which can be divided into tower buildings and plate buildings according to their external forms.

(1) Advantages of high-rise residential buildings: high land utilization rate, large outdoor public space and facilities, good view, convenient living in urban areas, and great attraction to property buyers.

(2) Disadvantages of high-rise residential buildings: High-rise residential buildings, especially towers, increase the difficulty of apartment design, and it is difficult to make the orientation, lighting and ventilation of each apartment on each floor reasonable. Moreover, the investment of high-rise residential buildings is large, and the consumption of steel and concrete in buildings is higher than that of multi-storey residential buildings. Need to configure elevators, high-pressure pumps, increase public walkways and doors and windows, and pay the recurrent cost of maintaining these equipment from the property management fee.

1 1 Small high-rise, how to choose the floor for buying a house, and which floor is the best?

1-6 storey residence is suitable for middle-aged and elderly families and families with children.

Stay close to the ground and keep in touch with the outside world. If there are old people and children at home, it is convenient to get in and out, and it is generally cheaper. The good lot has a relatively large construction area and is located in the landscape area of residential area, Jinjiao and Yinjiao apartment. Nowadays, many high-rise residential units are designed as "short depth and large area", which greatly broadens the horizons of residents and makes the indoor ventilation and lighting effect better. The application of some space treatment methods such as curved windows and walls makes every wall look smart, and even the low-rise apartment can achieve north-south orientation and flow through.

Disadvantages: the balcony can't see the sky and the distant landscape; The lower floors facing the street face noise and air pollution.

7- 1 1 storey residence, suitable for all ages and family combinations.

It has the advantages of high-rise and multi-storey residential buildings, which can not only have better ventilation and lighting conditions, but also have a more practical living experience. Prices are generally more expensive than low floors, similar to high floors, and some are more expensive than high floors.

Disadvantages: generally, you can't see the distant scenery on the balcony; High-rise buildings along the road are easy to form echo walls, and noise such as ground traffic will be reflected by low-rise buildings to high-rise buildings, so sometimes high-rise rooms will be noisy; At the same time, you can only see the opposite building, and the landscape will naturally be slightly inferior.

Is the 9- 1 1 layer a lime layer?

Many buyers will listen to other people's advice. When buying a house and choosing a floor, it is best not to buy the lime layer from the 9th floor to the 1 1 floor, which are the places where dust gathers the most. Is it correct to say 9- 1 1 ash layer in small and high-rise buildings?

Physics experts pointed out that the statement that the 10 layer is a gray layer does not conform to the common sense of atmospheric physics. Because at a height of 30 to 40 meters above the ground, the dust will not stop. Dust will not stop in the stratosphere from the ground 10 km to 52 km. In other words, there is no such thing as lime layer in ordinary high-rise buildings. Lime layer is just a statement, which has not been scientifically determined.

Under normal circumstances, pollutants in the air are constantly settling and flowing with the airflow. When there is no pollution source in the air, the higher the floor, the cleaner the air. The so-called "stagnant air" may refer to the phenomenon of "inversion layer" under normal circumstances. The higher the height of the atmosphere, the lower the temperature, and the air is easy to convection, so that pollutants can spread. However, in autumn and winter and under special climatic conditions, the temperature may increase with the increase of height, and an "inversion layer" will appear in the atmosphere.

The thickness of inversion layer varies from tens of meters to hundreds of meters, like a thick quilt covering the city, which hinders the spread of urban pollutants. However, the height of inversion layer changes, and the distribution of pollutants under inversion layer conditions also changes, and will not stay at a fixed height. Therefore, it is not accurate to judge the "grey layer" only by height.

1 1 floor, small high-rise, which floor is the best? This question is really a fair and reasonable question. What floor is best depends on the age composition of family members and the preparation of housing funds, because the higher the floor, the higher the price. In addition, developers of low-rise houses will sell and give away some areas, such as basements.

The difference between a banlou and a tower

Banlou refers to the building type of "east-west long, north-south short". Generally, there are 2 to 4 households on the same floor of a board building, while a tower refers to a type of building that looks like a tower. The length and width of the plane are roughly the same. Generally, there are more than 6 households on the same floor of the tower. So, what's the difference between a banlou and a tower?

Banlou is the name of the building structure. Generally, the number of floors of a board building will not exceed 12. On the plan of the banlou, the length is obviously greater than the width. There are two kinds of banlou, one is a long corridor, and each household is connected by a long corridor; The second is unit splicing, in which several units are connected together to form a slab building.

High-quality board buildings all adopt plate structure, so that elevators and corridors are located in the rear facade, and the sunrise gives way to the living room. The typical design is one staircase with two households. When facing north and south, there is plenty of sunrise in the front living room and master bedroom. In the east-west direction, there is a half-day sunrise in the front and rear rooms. In the organization of the room type, it is conducive to the straight-line flow of the wind as much as possible and always keeps the air fresh. At the same time, it also emphasizes the independence of residents, avoids the mutual vision caused by too many bumps between residents and too close windows, and ensures privacy well.

Towers generally refer to high-rise buildings, the housing density is higher than that of slab buildings, and there will be no transparent apartment in the north and south. The combination of tower plates is to set up tower units at the corner of the building.

Advantages of banlou

1, transparent north and south, convenient lighting and ventilation.

Plate houses are mostly in the north-south direction, and the depth is about 15 meters. Transparent north and south, convenient lighting and ventilation, square apartment, reasonable plane layout and appropriate functional space scale. Generally speaking, due to the sufficient width of the board building, it is easier for the apartment design to produce fine products.

2, the board building is good.

At present, the small banlou with one staircase and two households is very popular, precisely because there is little difference between the advantages and disadvantages of each apartment in the whole banlou, and it is difficult to deal with several apartments facing north. Because there are not many households in the banlou, life at home is relatively quiet.

3, the management cost is not high

Generally speaking, the management cost of slab building is generally lower than that of tower building, and multi-storey slab building can be built without elevators and variable frequency water supply system, and the daily maintenance cost including external wall painting is of course much cheaper than that of tower building.

4. The household usage rate is high.

The utilization rate of plate apartments is usually above 90%, while the utilization rate of tower apartments is usually only 75%, because the elevator shaft, waiting hall and power distribution room in the tower will be spread over each owner as public areas. The same is the purchase of housing with a construction area of 100 square meter, and the use area of plate-type apartment is often about100 square meter higher than that of tower residents.

Shortcomings of banlou

1, low building density and high housing price. Banlou communities are mostly low-rise buildings with low density and low floor area ratio. Although the living comfort is very strong, the house price will be high, especially in the urban areas where land is precious. The mainstream products are still towers, and a few non-working-class banlou people can afford them.

2. It is not suitable for rebuilding slab buildings, especially slab buildings with brick-concrete structure. Most indoor walls can't be changed because of their lifting function, so they are not as strong as towers.

Advantages of the tower

1, saving land resources and low house prices.

Because of the high building density of the tower community, it can save valuable land resources, effectively reduce the house price per square meter and let more people live in peace.

2. The spatial structure is flexible and suitable for transformation.

Towers mostly adopt large frame structure. Except for a few load-bearing beams, indoor partition walls can be basically dismantled and modified, and some towers can even be opened on the whole floor, allowing flexible division of apartment types.

3. High structural strength and good seismic performance.

Because the towering tower adopts frame structure and the floor is poured on site, the structural strength is higher than that of plate building, and the earthquake resistance and safety are good.

4. Take a long view.

Tower residents can enjoy the beautiful scenery of the city, and I believe that the houses in the low-rise board buildings can't feel this refreshing feeling.

The shortcomings of this tower

1, poor uniformity and high residential density. There are more than 6 households on each floor of the tower, even as high as 12 households. Hundreds of families are crowded into a big tower, and the living environment is definitely not superior to that of a banlou. Moreover, the lighting, ventilation and landscape conditions of some residents on each floor of the tower are relatively backward and cannot be changed.

2. The utilization rate is not high. The utilization rate of tower apartment in gray space is generally lower than that of board building 10 percentage point, and the kitchen, dining room and bathroom in the apartment are often not directly ventilated. Such a place is called "grey space".

Which is better, tower or banlou, actually depends on which individual buyers value more when choosing a house. It should be said that towers and banlou certainly have their own advantages and disadvantages.
