7. The stairwell, water tank room, and elevator machine room at the top of the building with enclosure structure shall have a structural height of m and above.

2. Calculate half of the area.

1. The construction area of the building, the structural floor height is below m.

2. For local floors, the height of the structure is below m.

3. The overhead layer of the building and the overhead layer of the slope stipend, the height of the structural layer is below m.

4. The corridor set up in the foyer and hall has a structural floor height of less than m.

5. Basement and semi-basement, the height of the structural floor is below m.

6. The door bucket has an enclosure structure, and the height of the structural layer is below m.

7. The stairwell, water tank room, and elevator machine room at the top of the building with enclosure structure have a structural height of less than m.

The floor area refers to the sum of the horizontal area of each floor of the building, including the usable area, auxiliary area and structural area. The usable area refers to the net area directly used for production and living in the floor plan of each floor of the building. Ancillary area refers to the net area occupied by the floor plan of each floor of the building for auxiliary production or assisted living, such as the area occupied by stairs, walkways, toilets, and kitchens in residential buildings.

The sum of the usable area and the auxiliary area is called the effective area. Structural area refers to the area occupied by walls, columns and other structures in the plane of each floor of the building.

1. Is the house price calculated according to the floor area when buying a house?

Buying a house is generally calculated based on the floor area.

There are several concepts about the size of a house that are often encountered during the process of buying a house:

1. The total construction area refers to the construction area of all houses in the community;

2. The construction area in the suite refers to the area used in the suite, the wall area in the suite, and the balcony area in the suite;

3. The shared area refers to the composition of public aisles, halls, elevators, stairways, garbage channels, water and electricity wells, equipment rooms and other common areas;

4. Construction area The shared area of the building area in the suite.

2. Which items are not included in the construction area of commercial housing.

1) The items that are not counted in the floor area of commercial housing include:

1. Houses with a floor height of less than 2 2 meters, basements and semi-basements with a net height of less than 2 05 meters.

2. Highlight the components, accessories, art decorations, buttresses, picks, semi-columns, legs, steps, etc.

3. There is no overhead passage between the houses.

4. Column-free awning.

5. The operating platform, feeding platform and the platform for placing boxes and tanks in the space of the building.

6. The part of the arcade and the street building is used for street traffic, and the part of the ground floor of the house is used for street and lane traffic.

7. The roof, balcony, garden and swimming pool of the house.

8. Outdoor ladders for fire fighting, maintenance and other purposes.

9. Structures, such as independent chimneys, flues, water towers, and oil (water) storage pools.

2) Matters related to the calculation of the area

1. Be wary of changes in drawings, for example, if the carport is rented out by the developer, it should not be included in the shared area.

2. Pay attention to the shrinkage of the floor height, such as changing the building to a duplex to shrink the height of the house.

3. Pooled area traps, for example, developers include the part that should not be pooled into the pooled area.

Specification for calculating the construction area: First, calculate the total area of 1, the construction area of 2, and the building with a structural height of 20m and above. 2. Local floors (according to the enclosed floor, according to the unenclosed floor), the structure height m and above.

3. The overhead layer of the building is raised to the oak, the overhead layer of the slope is stilted, and the structure height is m and above. 4. The structural height of the corridors set up in the foyer and hall is meters and above. 5. Basement, semi-basement, structural height of meters and above.

6. The gatehouse has an enclosure structure with a height of meters and above. 7. The structural height of the stairwell, water tank room and elevator room of the top envelope of the building is m and above. Second, calculate half of the area 1, the building area and the height of the structure is less than 2 meters and 20 meters.

Floor-to-ceiling windows attached to the exterior wall of the building, the structural height is less than 2, the height difference between the window sill and the indoor ground is less than 0 to 45m, and the structure net height is more than 2 to 10m convex (floating) windows. 12. The width from the structural edge of the porch, columned awning and columnless awning to the structural edge of the exterior wall is m or more.

13. The building envelope is not perpendicular to the horizontal plane, and the net height of the structure is above m to below m. 14. The roofed lighting well should be calculated according to the area of one floor, and the net height of the structure should be below m. 15. The net height of the sloping roof constituting the building space is the building space below the stadium stands, and the net height of the structure is m respectively.

Legal analysis: The Rules for the Calculation of Construction Area are revised on the basis of the Rules for Calculating the Quantity of National Unified Construction Project Budgets issued by the Ministry of Construction in 1995 in accordance with the requirements of the Notice on Printing and Distributing (Jianbiao No. 200467) of the Ministry of Construction. Its purpose is to meet the needs of the project cost valuation work, this code in the revision process fully reflects the impact of the new building structure and new technology on the calculation of the construction area, considers the habits of the calculation of the construction area and the international general practice, and at the same time with the "residential design code" and the "real estate surveying code" The relevant content has been coordinated.

It was promulgated and implemented by the Ministry of Construction of the People's Republic of China on April 15, 2005.

Calculation rules for building area: construction area, building area in the suite, shared area.

The construction area refers to the sum of the horizontal projection area of the periphery of each floor above the foot of the external wall (column) of the building, including balconies, corridors, basements, outdoor stairs, etc. The shared area refers to the area of public building space in the commercial housing that should be apportioned into the sales area in the sale of commercial housing.

Pooled area Pooled coefficient Floor area of the set. Pooling coefficient Total communal area (floor area of units, total number of units). Set of construction area, set of usable area, wall area.

Floor area:

When a buyer buys a house, the floor area generally refers to the sale area of the house. Specifically, it refers to the floor area formed by the building, including the outdoor balcony, awning, eaves corridor, outdoor corridor, basement, outdoor staircase, etc., attached to the building, and has a permanent building with a cover, a firm structure, and a floor height and above.

The construction area is also related to the collection of property fees and heating fees when buyers buy and move in, because these are charged according to the square meters of the construction area.
