How to calculate the area of the community?

Question 1: How to calculate the building area: all the land area occupied by the community, including corridors, gardens and red lines.

The land area occupied and used by the building, the design construction area of the building is calculated according to the horizontal area of the periphery above the foot of the bottom external wall.

Because the calculation rules and area connotation of building area and building area are different. For example, each house is 70 square meters. Is this area the building area, interior area or usable area?

In terms of housing area, there are different standards for calculating the area of many parts, such as whether the balcony is closed or not determines the building area of the house.

Question 2: Does the residential area enter the pool area? The Rules for the Calculation of Commercial Housing Sales Area and Allocation of Public Building Area issued by the Ministry of Construction clearly stipulates that:

Article 6 Sales area of commercial housing = interior construction area+shared area of public parts.

Article 8 The public building area includes:

1, elevator shaft, stairwell, garbage chute, power distribution room, equipment room, public hall and aisle, basement, duty room and other functional building areas are the whole building.

2 basements and carports that have been sold or rented as independent use space are not included in the public area.

So 1 has roads, lawns, tunnels, basketball courts, parking spaces, artificial lakes and so on. Between each building, it belongs to the outside of the building and is not included in the pool.

2. It is pointed out in the Property Management Regulations that it belongs to all owners, but the developer will add clauses when signing the contract to classify this part under the name of the developer or the sole owner (for example, the garden given by 1 building was given to the owner of 1 building).

Question 3: How to calculate the landscape design area of the community? The calculation formula of the landlord's landscape area is debatable.

The calculation formula of landscape area is: area within the planning red line+(building area of the first floor or ground floor)+municipal road area+overhead building area+roof landscape area+the part specially designed by Party A). "

Whether it should be: the area within the planning red line-(minus the building area of the first floor or basement)-minus the municipal road area+(overhead building area+roof landscape area+the part specially designed by Party A), if any. And generally speaking, the "landscape area" will not be greater than the "land area within the planning red line".

Question 4: How to calculate the area of public land for residential demolition? Total area of collective demolition minus private area and other areas = public land area.

Question 5: What do the basement area and floor area ratio mean in architectural design? How to calculate? The reference area basically refers to the total area of the plot where the building is located.

It is usually surrounded by road red lines.

The simplest formula

Floor area ratio = total construction area/total land area

for instance

You built a three-story house on a piece of land 10000 square meters, with each floor 1000 square meters.

Then the plot ratio of your land is

1000x3/ 10000=0.3

Question 6: What proportion of public buildings in a residential area should account for the total construction area of the residential area? 5. The public facilities in residential quarters are controlled by the population of residential quarters. Usually, such public facilities (including commercial facilities) will account for 5% of the total construction area of the community.

Residential ancillary facilities refer to residential ancillary facilities necessary to create a hygienic, safe, quiet and comfortable living environment for urban residents. Generally, it can be divided into seven categories: educational facilities, medical and health implementation, cultural and sports facilities, community service and administrative facilities, postal and municipal facilities, commercial services and others.

(1) Educational facilities include kindergartens, primary schools and secondary schools.

(2) Medical and health facilities generally include health stations and health service centers. (3) Cultural and sports facilities include: comprehensive cultural activity center, cultural activity station, and residents' sports ground/gymnasium.

(4) Community services and administrative facilities include: elderly welfare homes, elderly service centers, foster care centers, elderly service stations, nurseries, municipal management houses, community service centers, community neighborhood committees, property management houses and owners' committees; (5) Postal and municipal public facilities include gas supply stations, substations, garbage compression stations, post sub-offices, public toilets and social service facilities.

(6) Commercial services include: meat market, department store, etc.

(7) Others generally refer to public power distribution room, pool and pump room, boiler room, switching station, heat exchange station, etc.

Question 7: How to calculate the pool area of the community? The pool area is all public areas including elevators. . Corridor. . . The lobby. . . It's all in your room area . . . Buy the top floor now. The ingot pool has a large area. . . . The occupancy rate is less than 80%. . . .

Question 8: Know the building area and floor area ratio. How to calculate the total construction area? I don't know if the land auction area you mentioned is the total land area of this plot. If so, then the total land area × floor area ratio is the total building area you can build. This total construction area is not the total land area of the building, because the land area refers to the area where the building is in contact with the ground, which means that the total land area × building density is the total land area of the building. Green space rate is the ratio of green space area to total land area. Pay attention to the difference between green areas and green areas. The area of green space refers to the area you use as green space. The green area refers to the orthographic projection area of all greening on the ground, that is to say, including the orthographic projection area from the crown to the ground. Many times, developers will fool buyers here, and what needs to be vigilant is the green rate or the green rate.
