In our daily life, we often see buildings of different heights. According to the form of residential buildings, it can be divided into low-rise, multi-storey, small high-rise, high-rise and super high-rise. So, what is the difference between them?

First, the lower level

Refers to a 1-3-storey house (including 3 floors). In cities, most of them are villas; In rural areas and towns, they are generally ordinary houses.

Because the total number of floors is 1-3, residents can be closer to nature and have better living comfort and privacy. Its disadvantage is that it is not conducive to the improvement of the utilization rate of land resources, and it is more expensive to buy such a house in the city.

Second, multi-layer

Refers to the 4-6 floors (including 6 floors) of the house. Multi-storey residential buildings generally have one staircase and two households, and each household can realize natural ventilation in the north and south, which basically meets the lighting requirements of each room. Multi-storey houses need not be equipped with elevators, and stairs are often used as the main passages for the upper and lower floors of multi-storey houses. Generally, the second and third floors are the most expensive. There are also a few multi-storey residential quarters with elevators, which are generally called multi-storey houses, and the second one is the most expensive.

Comparison between multi-storey houses and high-rise houses;

1. Generally speaking, the building standards and quality of high-rise buildings are higher than that of multi-storey buildings. If you live on a higher floor, you will have a wider view, better air quality and lower noise.

2. The occupancy rate of high-rise buildings is lower than that of multi-storey buildings, that is, the indoor construction area of high-rise buildings is lower than that of multi-storey buildings.

3. The high-rise property management fee is higher than the multi-storey property management fee.

Third, small high-level.

Refers to the residential building with a total floor area of 7- 1 1 (including 1 1). In a broad sense, it is also called small high-rise buildings within 18. Their plane layout is similar to that of multi-storey houses, with one staircase and two households and small pool area. Characterized in that:

1. The floor area ratio of buildings is higher than that of multi-storey houses, saving land.

2. From the perspective of the plane layout of the building structure, most of them adopt plate structure, 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.

Fourth, the top

Refers to the total number of floors above 12, but the building height is less than 100 meters. The advantage of high-rise housing is that it can save land and increase housing and population. The architectural forms of high-rise residential buildings include slab buildings, towers and slab towers. Due to the limitation of architectural structure and architectural form (mostly point-shaped), it is difficult to design the room type, and it is very difficult to make every room bright, well-lit and well-ventilated.

Advantages: For residents, it has wide vision, high landscape coefficient, good visibility, less dust, noise and light pollution, high structural strength and strong integrity.

Disadvantages: the construction cost increases accordingly; High-rise residential elevators, corridors, computer rooms, technical floors and other public parts occupy a large area, and the room rate is low; If the elevator quality is unreliable and the property management is not good, it is very worrying.

Five, super high-rise.

Super-high-rise refers to houses with a building height exceeding 100 meters, and the total number of floors is generally more than 33. The floor price of super-high-rise residence is the lowest, but its house price is not low. This is because with the continuous increase of building height, its design method, concept and construction technology will change greatly compared with ordinary high-rise residential buildings and low-rise residential buildings, and the factors to be considered will increase greatly. For example, the number of elevators, fire-fighting facilities, ventilation and smoke exhaust equipment, and personnel safety evacuation facilities will be more complicated, and the earthquake resistance and load of the structure itself will be greatly strengthened. In addition, the super high-rise building is highly prominent and eye-catching, so the decoration of the external wall is also high, which leads to high cost.

There are many kinds of houses, mainly divided into high-grade houses, ordinary houses, apartments, townhouses and so on.

(1) According to the building height, it is mainly divided into low-rise, multi-storey, small high-rise, high-rise and super-high-rise buildings.

Low-rise residence mainly refers to (one family) detached residence, (two families) vertical residence and (many families) townhouse. Compared with multi-storey and high-rise houses, low-rise houses have the most natural affinity (often with special residential courtyards) and are suitable for children or the elderly. There is little interference between residents and a pleasant living atmosphere. Although this kind of residence is loved by residents, it is limited in the total supply due to the objective conditions such as land price and utilization efficiency, high politics and supporting facilities, scale and location.

Multi-storey residence is the most representative urban collective residence, which mainly depends on the vertical traffic of public stairs. Compared with middle and high-rise buildings (small high-rise buildings) and high-rise houses, it has certain advantages:

1) In terms of construction investment, multi-storey residential buildings do not need to increase the investment in elevators, high-pressure pumps and public walkways like middle and high-rise residential buildings.

2) In terms of apartment design, multi-storey residential apartment design space is relatively large and living comfort is high.

3) In structural construction, multi-storey houses usually adopt brick-concrete structure, so the construction cost of multi-storey houses is generally low.

However, multi-storey houses also have shortcomings, mainly in:

1) The living conditions on the ground floor and the top floor are not ideal, the safety and lighting of the residents at the bottom floor are poor, and the toilet is easy to overflow and smells; The top floor residents are inconvenient to get on and off because there is no elevator. In addition, the roof has poor heat insulation and water resistance.

2) Innovation is difficult. Due to the stereotyped design and construction technology, it is difficult to innovate in the structure, building materials selection and spatial layout of multi-storey houses, resulting in the disadvantages of "one thousand buildings on one side". If we want to innovate, we need to increase investment and lose the advantages in price and cost.

There are many plane types of multi-storey houses, the basic types are stairs, corridors and independent units.

Small high-rise residential buildings mainly refer to collective residential buildings with floors 7 to 10. 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. Compared with multi-storey houses, this small high-rise building has its own characteristics:

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) The building structure of this kind of small high-rise residence mostly adopts 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 of the design of the elevator, 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.

(2) According to the structural form of the building, it is mainly divided into brick-wood structure, brick-concrete structure, steel-concrete frame structure, steel-concrete shear wall structure, steel-concrete frame-shear wall structure and steel structure.

(3) According to the classification of architectural forms, it is mainly divided into low-rise houses, multi-storey houses, medium-high-rise houses, high-rise houses and other forms of houses.

(4) According to the types of houses, they are mainly divided into ordinary units, apartments, duplex houses, duplex houses, garden houses, small-sized houses (super-small-sized houses) and so on.

(5) According to the classification of housing policy attributes, it is mainly divided into low-rent housing, purchased public housing (reformed housing), affordable housing and housing cooperatives to raise funds to build houses.
