What exactly is a banlou?

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.

First, the definition of high-quality banlou adopts plate structure, and the banlou in front of the living room and master bedroom has sufficient sunrise; In the east-west direction, there is a half-day sunrise in the front and rear rooms.

In the organization of room type, it is beneficial to the straight-line flow of wind as far as possible.

Second, the quality (a) control the proportion of width and depth.

The development of banlou experienced a long period in 1980s, and gradually transitioned to a pure banlou with high comfort.

The former has obvious shortcomings because there are few elevators, but the latter is one elevator and two households, and it ensures a certain width to make the sun full, and at the same time, it more perfectly configures various functional areas.

It also overcomes the disadvantages of monotonous garden planning and barracks layout, adds slots in the building to form toilets and restaurants, and effectively improves the comfort.

Therefore, we should try to choose the apartment with short depth and large width.

Generally speaking, the low-rise slab depth is controlled within 14m, the high-rise slab depth is controlled within 18m, and some units exceed 20m.

If you don't rely on the lighting on both sides of the board building, choose carefully as far as possible, because too much depth will increase the indoor gray space and affect the living comfort.

The area width depends on the size of the apartment. Generally, the type of banlou is more than two bedrooms, with the width of two bedrooms ranging from 6m to 8m, three bedrooms ranging from18m to13m, and four bedrooms ranging from12m to15m.

(2) Pay attention to the sunshine in the bedroom and living room.

In the design, it is important to consider the strict distinction between the location of the room and the auxiliary room, and the separation of static and dynamic, which is the advantage of the board building.

In terms of apartment spacing, the entrance is the hall or porch, and the dining room is adjacent to the kitchen and placed on the back side.

The living room and master bedroom are located on the Chaoyang surface.

At the end of the corridor is the master bedroom.

In terms of orientation, the north-south orientation of the apartment is generally "two-bedroom, with the master bedroom and living room facing south, or two-bedroom facing south and living room facing north;" Three bedrooms, master bedroom, one secondary bedroom or study and living room facing south, or master bedroom and living room facing south, the other two secondary bedrooms facing north, or three bedrooms facing south and living room facing north; Four-bedroom, three-bedroom and living room face south, or two-bedroom and living room face south, or three-bedroom faces south and living room faces north.

As the east-west direction of the banlou, the east side is the main direction, and other laws are the same as the north-south direction.

The biggest advantage of banlou is that the apartment is regular, with small mutual vision and good ventilation and sunshine. Therefore, try to choose straight plate buildings, and U-shaped and Z-shaped plate buildings should be carefully considered according to sunshine and mutual viewing.

However, the small number of units is also the disadvantage of the board building.

Advantages: Most of the north-south transparent plate houses are 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.

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.

Low cost Generally speaking, the management cost of slab buildings is generally lower than that of towers. Multi-storey houses can be built without elevators and variable frequency water supply systems, and the daily maintenance costs, including external wall painting, are of course much cheaper than tower buildings.

The utilization rate of high-utilization banlou apartments is usually above 90%, while the utilization rate of tower apartments is usually only 75%, because the elevator shaft, elevator waiting hall and power distribution room in the tower will be spread over each owner as public areas.

For the same housing with a construction area of 100 square meter, the use area of plate-type apartment is often about100 square meter higher than that of tower-type households.

(3) Disadvantages 1. Low building density and high housing prices. 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, and the mainstream products are towers, which a few non-working-class people can afford.

2. The apartment type is not suitable for rebuilding the slab building, especially the slab building 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 and disadvantages coexist Objectively speaking, there is no absolute difference between a tower and a banlou.

In fact, the tower with advanced planning and reasonable design will not be inferior to the board building in terms of square and practical apartment type, clear functional division and ventilation and lighting effect.

Although some high-rise buildings on the market are slab buildings, they are not satisfactory in depth and width, floor area ratio and uniformity. For example, if a high-rise slab building is built, the depth will inevitably increase, reaching 15- 16 meters, and the lighting is not thorough. Due to the favor of small huxing in the market, the width of small huxing with large depth will inevitably decrease, resulting in insufficient transparency.

In addition, although the north-south permeability of banlou is good, many banlou are designed in the east-west direction, which can not achieve the ideal effect. Therefore, since 2002, more and more developers have realized the disadvantages of high-rise board buildings and have developed small high-rise or multi-storey board buildings.

The developer of the tower gradually realized the disadvantages of aerial painting, and adjusted the design of 18 households to 12 households on the first floor to 5 to 6 households on one staircase, transforming the traditional bloated "King" tower into a comfortable and healthy thin tower and butterfly tower.

Third, the classification comparison board building tower buyers can distinguish from the building plan.

The tower has several characteristics, such as the building plane formed by four or five households surrounding or surrounding a group of public vertical traffic, and the length and width of the plane are roughly the same.

The length of a banlou is obviously greater than its width, and there are roughly two kinds of banlou: one is a long corridor, through which residents are connected; The second type is unit splicing, in which several unit slab buildings are connected together to form a slab building.

Simply put, the tower is relatively high, and the board building is relatively short and long.

How to build a flat apartment is subject to two factors: depth and width. Generally, flat floor units increase the sales area by increasing the depth, but the lighting effect will be affected when the depth is large.

And generally speaking, it is difficult to have a spacious lobby on the ground floor because of the building structure.

Moreover, the board building occupies a relatively large area, which may reduce the green area of the community.

Although it is impossible for the tower to face south, the Butterfly Tower and the newly launched "Dianlou" have improved the tower in order to make more houses face south.

The advantage of the tower is that the general ground floor can be built into a gorgeous lobby, with different room types and orientations, and more room for price choice.

But the utilization rate of tower building is lower than that of plate building.

Which is better? Towers and banlou have their own advantages and disadvantages.

Which type of building is better depends on the principle of individual housing selection.

In addition to the requirements for lots, ordinary buyers are most concerned about the price, environment, huxing, the consumption level of target buyers, and the requirements for greening rate and floor area ratio.

This determines the housing price, greening rate, floor area ratio and other indicators.

When choosing a house, the most important indicator that affects the environment is the green rate. The higher the greening rate, the better the environment, and of course the higher the price. The floor area ratio determines the apartment type and area. The lower the floor area ratio, the better the living comfort, but the same price will be higher.

Therefore, in general, the price of slab buildings will be higher than that of tower buildings, because the former is more comfortable than the latter. However, many developers have developed products combining plate and tower to meet the needs of different architectural styles and price points, which also increases the unity index.

Fourth, the market trend A few years ago, there was a dispute between the banlou and the tower in Beijing: some people strongly praised the banlou, thinking that it was both ventilated and sunny, with high utilization rate; Some people also defend the tower, arguing that different huxing, different orientations and various prices broaden the scope of choice. At the same time, compared with the banlou, the lobby can be made wider and more gorgeous, and the garden pattern of the community is also more colorful.

Of course, although banlou has the advantages of apartment layout, it is prone to defects in garden planning, such as: the layout of camps and determinant in large communities is monotonous; In the total area of residential area, the building occupies a large area and the green space is relatively small.

The shortcomings of the tower are more manifested in the apartment type: the rooms are easy to be distributed around, the shape is changeable, and it is not easy to achieve unity; Compared with the board building, it has poor ventilation and low utilization rate.

Natural advantages Pure plate buildings all adopt plate structure, so that elevators and corridors are located in the rear facade, and 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.

With the development of housing, a short board building with only two or three doorways began to appear. It not only maintains the advantages of pure board building, but also overcomes the shortcomings of monotonous garden planning and barracks layout. Slots are added in the building to form a bright bathroom and a bright restaurant, which effectively improves the comfort.

The biggest advantage of banlou is that the apartment is regular, with small mutual vision and good ventilation and sunshine. Therefore, try to choose straight plate buildings, and U-shaped and Z-shaped plate buildings should be carefully considered according to sunshine and mutual viewing.

But at the same time, the small number of units is also its disadvantage.

In the early days, all kinds of towers were square and bloated. In order to solve the ventilation and lighting of each apartment, buildings often have to open deep slots, which not only leads to a "gray room" with extremely limited lighting, but also brings mutual vision to adjacent suites.

So after the square tower and T-shaped building, the tower evolved into the shape of a well, windmill and butterfly.

Compared with plate building, the advantages of tower are: the facade is changeable, which is more suitable for wide-angle windows such as corner windows and arc windows; Diversified room types and prices give users more choices; Public parts such as lobby and elevator hall are easy to design because of the deep pedestal; The dotted layout of the tower is much more lively than the linear layout of the board building in the garden landscape of the community.

At the same time, however, the obvious shortcomings of the tower are: the utilization rate is low due to the large pool, the ventilation and lighting are easily blocked by buildings, the probability of mutual viewing between adjacent suites is too high, and the privacy of multiple elevators on each floor is difficult to guarantee.

Due to the increasing shortage of land resources, the mainstream of housing leads to the emergence of low-density housing in urban areas, which on the one hand increases the development cost, on the other hand makes the precious land resources unable to effectively meet the needs of the expanding urban population.

Therefore, urban housing is more reflected in high-density housing.

Judging from the planning of Beijing, the new houses within the Fourth Ring Road are mainly high-density, and the floor area ratio is controlled between 2.5 and 5. The architectural forms are mainly high-rise and small high-rise towers, slab buildings and slab towers, and some areas are interlaced into medium-density garden houses.

Although high density has the problem of living environment, it can effectively save land resources, expand traffic allocation and improve the utilization rate of various facilities. The vacated land can increase the green area and improve the urban landscape and air index, so it is still the main living form of major cities in the world.
