What is the floor area ratio to be considered a low density house?

Floor area ratio. The following is considered a low-density dwelling. Detached villas for, townhouses.

For. Build a house on a plot of land with an area of 100 square meters, with a construction area of 100 square meters per floor, and build 2 floors with a total construction area of 200 square meters, and the plot ratio is; If 3 floors are built, the floor area of each floor is 50 square meters, and the total construction area is 150 square meters, the floor area ratio is, and so on.

The total land area is 100,000 square meters, the total construction area is 80,000 square meters, and the plot ratio is; The total land area is 100,000 square meters, the total construction area is 100,000 square meters, and the plot ratio is 1; The total land area is 100,000 square meters, the total construction area is 150,000 square meters, and the plot ratio is; In the case of the same number of floors, the smaller the floor area ratio, the smaller the living density, which is relatively comfortable. The larger the floor area ratio, the opposite is true.

The floor area ratio is the floor area of the ground divided by the area of the land.

Housing density is the area occupied by the house divided by the land area.

For example, if a land area of 10,000 square meters is built and a 12,000-square-meter house is built, the ground floor area of the house (that is, the floor area of the ground floor of the house) is 2,500 square meters.

Then the floor area ratio = 12000 10000 =

Building density = 2500 10000 = 25%.

Based on these two indicators, we can launch at least how many floors the house should be built. Because the floor area of the house is the same, the floor of the house is the least under the given plot ratio, therefore, 12000 2500 = floors = 5 floors. This means that at a building density of 25% and a floor area ratio, the building on this land must be built with at least 5 floors.

Since the standard floor height of a house is 3 meters, we know that the building is at least 15 meters high.

To sum up, the floor area ratio and building density are two very important planning indicators, as long as the planning bureau sets these two indicators, the general outline of the house will also come out.

Question 1: The concept and difference between floor area ratio and building density!! Plot ratio = total building area Total land area.

This value can be greater than 1

Building density = total area of building base Total land area.

This value is a percentage.

For example, if a piece of land is 10,000 square meters, of which a 5-story building covers an area of 3,000 square meters, the building density of this land is 3,000 10,000 = 30%. And the floor area ratio = 5 * 3000 10000 =

Here's another list:

If you build a 1 square meter house on 1 square meter, if it is one floor, the plot ratio is 1, and if it is 2 floors, the plot ratio is 2.

In other words, the dissolution rate is related to the number of floors in the building, and the higher the number of floors, the greater the floor area ratio.

Question 2: What is the relationship between building density and floor area ratio? The plot ratio is the control index given by the planning department to the construction intensity of a certain plot, that is, how many areas of buildings can be built on this land

Floor area ratio Total floor area Total land area General building density is also the construction control index of the planning authority on the plot, building density Building ground floor area Total land area Therefore, the floor area ratio is certain, that is, the total construction area is certain, and the building density is inversely proportional to the number of building floors.

Question 3: What is the difference between building density and floor area ratio? Floor area ratio = total building scale (above ground) divided by total construction land area, general low-density floor area ratio, general high-rise floor area ratio above.

Building density = building base area divided by total construction land area, which is a percentage, and the value is less than 1

Question 4: What is the difference between building area density, building density and floor area ratio Assuming the total land area, 80 acres is the construction land area, and the rest is the collection of roads and greening.

Plot ratio: above-ground construction area construction land area = 35000 80 * 666 =

Note: The local planning bureau has different opinions on whether the floor area ratio is added to the underground area, please check the local standards.

Building density cannot be calculated based on the above conditions, Note: Building density: building base area (i.e. the sum of the first floor area of all buildings) Construction land area.

Question 5: What is building density? Building density: refers to the ratio of the area occupied by the first floor of the building within the project land area to the planned construction land.

For example: 1000 square meters of construction land, 400 square meters of basement, 300 square meters of ground floor, then: building density of 30. In this way, it can be seen that the area of the base and basement is not directly related to the building density. (This answer emphasizes the area of "one floor").

Question 6: What is the difference between the planned floor area ratio and the planned building density The plot ratio = the total area of the building The total land area.

Building density = first floor building land area Total land area.

There is no specific quantity, it needs to be on a case-by-case basis. The lower the plot ratio, the more upscale the dwelling, because the lower the plot ratio, the lower the building density, and the lower the building density.

1. The plot ratio is lower, which is a very high-end single-family villa project.

2. Floor area ratio, general single-family villa projects.

3. Floor area ratio, general double-detached and townhouse.

4. For example, on a land of 10,000 square meters, there is a total area of about 4,000 square meters of construction tourism, and its floor area ratio is as follows. Your example of 7 means that the project assumes a total building area of 70,000 square meters on 10,000 square meters of land, and its plot ratio is 7.

5. The effect of floor area ratio on the land price of different types of land is different. Commercial land is the most sensitive to location conditions, can only be laid out in a small number of superior location conditions along the road area, land scarcity, supply and demand contradiction is more prominent than residential and industrial land, easy to form a seller's market, the competition of many land users to promote the increase of floor area ratio to produce economic surplus mainly in the form of land price, owned by the landowner;

6. The sensitivity of residential land to location conditions is weaker than that of commercial use, but stronger than that of industrial land; Industrial land is generally distributed in the periphery of the city, which is not only the least sensitive to location conditions, but also restricted by the technological process, and in many cases there is no restriction on the plot ratio. Therefore, in the same city, the influence of plot ratio on different types of land prices is commercial, residential, and industrial land in descending order.

The right building density is:: The 4-storey building area can generally be about 26%, the 5-storey building area can generally be about 23%, and the 6-storey building area is not higher than 20%. The building density generally does not exceed 40%-50%, and part of the land needs to be set aside for roads, greening, squares, parking lots, etc.

The appropriate floor area ratio is:: Detached villas, townhouses, multi-storey residences with less than 6 floors, small high-rise residences with 11 floors, high-rise residences with 18 floors, residences with more than 19 floors, and residential areas with a plot ratio of less than are non-ordinary residences.

There is an objectively reasonable value for the floor area ratio. In general, increasing the floor area ratio can improve the efficiency of land use, but the increase of building capacity will bring about the deterioration of the building environment and reduce the comfort of use. In order to achieve the coordination of economic, social and environmental benefits, there is an objectively most reasonable value for the floor area ratio in urban planning.

Turn left|Turn right.

A good residential community, the plot ratio of high-rise residential buildings should not exceed 5, multi-storey residential buildings should not exceed 3, and the green space rate should not be less than 30%.

For details, you can refer to the residential area specifications, and it is best to look at the local urban planning and management technical regulations.

1. The concepts of building density and floor area ratio are different.

1) Floor area ratio is also known as gross density of building area. It is an important indicator to measure the intensity of construction land use. The value of the plot ratio is a dimensionless ratio, usually the plot area is 1, and the total floor area of the buildings on the plot is a multiple of the plot area, that is, the value of the plot ratio.

The ratio of the total above-ground construction area (but must be the construction area above plus or minus 0 elevation) to the total land area of the project within the project land area. Refers to the ratio of the total above-ground floor area to the land area of a community.

2) Building density: Specifically, it refers to the ratio of the total area of the building within the project land area to the planned construction land area ( ) It can reflect the vacant land rate and building density within a certain land area.

2. The calculation methods of building density and floor area ratio are different.

1) Building density calculation formula: building density The sum of the base area of the building and the area of planned construction land.

2) Plot ratio calculation formula: plot ratio, total above-ground construction area, buildable land area.

Floor area ratio: refers to the ratio of the total floor area to the area of building land.

Net density of residential floor area: the residential floor area (10,000 m2 hm2) owned per hectare of residential land.

Building density: The proportion of the total area of the base area occupied by all buildings (%)

Net density of residential buildings: ratio of total area of residential building substrate to area of residential land (%)

Building density: that is, the ratio of the area of each building substrate in the planning plot to the area of the plot.

Calculation formula: building density = building base floor area plot area.

For developers, the plot ratio determines the proportion of land cost in the house, while for residents, the plot ratio is directly related to the comfort of living. The same is true for the greening rate. The higher the greening rate, the lower the plot ratio, the lower the building density, the less area the developer can use for the first time, and the more comfortable the residents.

These two ratios determine whether the project is designed from the perspective of people's housing needs or purely from the perspective of making money. For a good residential community, the floor area ratio of high-rise residential buildings should not exceed 5, multi-storey residential buildings should not exceed 3, and the greening rate should not be less than 30%. However, due to the cost of land, not all projects can be done.

The floor area ratio is about 50 lower than the net floor area ratio. Both of these indicators are legitimate, and unless otherwise specified, when talking about floor area ratio, it generally refers to the net floor area ratio. However, the state does not explicitly stipulate that developers can only publicize the net floor area ratio, so some developers take advantage of the loopholes in the law to convert the net floor area ratio into gross floor area ratio to publicize, buyers do not understand the mystery, and think that the floor area ratio of this community is really low, only to find out that they were fooled after moving in.

The lower the floor area ratio and the smaller the living density, the higher the living comfort, and the lower the comfort. However, for developers, the plot ratio determines the proportion of the cost of land price in the house** and determines the gold content of the developed land. Therefore, the higher the plot ratio, the greater the profit for the developer.

1. Floor area ratio = (factory building area + structure area) Plant area.

Floor area ratio, also known as gross floor area density, refers to the ratio of the total above-ground floor area to the land area of a community. For developers, the plot ratio determines the proportion of land cost in the house, while for residents, the plot ratio is directly related to the comfort of living. A good residential community, the plot ratio of high-rise residential buildings should not exceed 5, multi-storey residential buildings should not exceed 3, and the green space rate should not be less than 30%.

However, due to the cost of land, not all projects can be done.

2. Building density = (building area, structure area, yard land area) 100% of the total land area of the project.

Building density, refers to a certain range, the sum of the base area of the building to the total land area of the ratio (%) refers to the coverage rate of the building, specifically refers to the ratio of the total area of the base area of all buildings within the scope of the project land to the area of planned construction land (%), which can reflect the vacant land rate and building density within a certain land range.

Land volume ratio is an important technical and economic indicator of urban planning and land management, and its specific meaning refers to the total number of buildings carried on the land per unit area (hectares), and the unit of measurement is 10,000 hectares. The higher the plot ratio, the higher the development intensity of the land, and vice versa, the lower the development intensity. It is usually used in conjunction with the floor area ratio and the building density index, which refers to the ratio of the ground floor of the building to the total land, the larger the ratio, the denser the building; The smaller the ratio, the sparser the building.

In general, the plot ratio of a piece of land is negatively correlated with the built environment and positively correlated with the economy of the land. In order to ensure the unity of urban economic, social and environmental benefits, the state has certain limits on the floor area ratio in the relevant specifications of urban planning, and the maximum floor area ratio of multi-storey buildings is not allowed to exceed, and the maximum building density is not allowed to exceed 30%.If the green space rate and vacant land rate in the residential area exceed the upper limit, the specified standards will not be met, and the quality of the living environment will be affected
