Large construction area or large usable area

Don't talk nonsense upstairs, can you pretend to understand if you don't know how to understand.

First of all, I want to say that the developer said that the 270 for your home is the construction area (the construction area is composed of the usable area, the structural area and the auxiliary area), and the white point is that the area you can use is about 70%-80% of the construction area, which is the usable area here. The other 20%-30% is the area occupied by the shared area, walls, columns and other structures.

The second one is that you have to choose a plan, and I think the 115 90 65 one is better. Because the 115 square meter house is more suitable for your own family to live in, like you have any children, friends and relatives go to your house, you can live at any time, and 90 and 65 are obviously small and medium-sized houses and small houses, these two houses you can sell or rent, it depends on your actual situation, these two types of houses are usually easier to sell or rent, and finally I have to tell you 115 This house type should be OK, and 90 and 65 This is not very good, this specific you still have to go to the scene to see what kind of house type What floor and what location And the orientation of the house, if the construction party does not let in now, it is possible, if this situation occurs, you can go and see their drawings and listen to the construction staff talk about the specific situation of the house. I'm not going to be exhaustive, but I hope it can help you.

It is the floor area, and the floor area is greater than the usable area. Because the construction area includes the shared area and the usable area.

270 is the floor area, and the others are the usable area.

Difference: The construction area is larger than the usable area, and the construction area is the area occupied by the wall and the shared area on the basis of the usable area.

The part of the space included is different, and the building area includes the usable area, the area of the interior wall, half of the area of the exterior wall, and half of the area of the sub-household wall and the shared area. The usable area of the suite includes the sum of the usable net area of the kitchen, dining room, living room, bedroom, etc., excluding all the floor space such as interior walls and exterior walls.

Floor area refers to the sum of the horizontal area of each floor of a building, including usable area, auxiliary area and structural area.

The construction area is an economic indicator that indicates the size of the building, and it is also a physical quantity index that reflects the scale of building construction in square meters.

Floor area: The floor area includes the usable area, and also includes the shared area, which is the purchase area shown on the real estate certificate of the house. The construction area is not all within the scope of direct use, but the usable area is within the actual use range.

For example, toilets, kitchens, bedrooms, living rooms, study rooms, game rooms, etc. The usable area of the house can be measured by yourself at the time of delivery, and the developer will only tell you the approximate usable area and the shared area.

Usable area: refers to the horizontal projection area of all usable spaces in the sub-household (suite) door of the dwelling in the unit of household (suite), including bedroom, living room and living room, kitchen, bathroom, indoor walkway, staircase, closet, balcony, basement, mezzanine, attic and other areas used in daily life. The built-up area of the house is composed of three parts: the usable area of the suite, the wall area of the suite, and the floor area of the balcony in the suite, that is, the usable area of the house is part of the built-up area of the house.

One square kilometer refers to the area, and one kilometer refers to the length or width, which are two concepts. One kilometer multiplied by one kilometer equals one square kilometer, which means that one square kilometer is the area of a square with a length and width of one kilometer.

The size of the flat figure occupied by an object is called their area. Area is the size of the flat figure occupied, square meters, square decimeters, square centimeters, is a recognized unit of area, which can be expressed by letters as (m, dm, cm).

The usable area of a dwelling refers to the sum of the net area directly used by the residents in the floor plan of each floor of the dwelling. Calculating the usable area of a dwelling can more intuitively reflect the use of the dwelling, but it is generally not used to calculate the usable area in the purchase and sale of a dwelling**.

There are some special provisions when calculating the usable area: the indoor staircase in a duplex dwelling is counted as the sum of the areas of the natural floors; Chimneys, ventilation ducts, and pipe wells that are not included in the structural area are included in the usable area; The thickness of the interior wall decoration is included in the usable area.

The floor area of the dwelling refers to the horizontal area of the space enclosed by the outer wall of the building, and if you seek the floor area of the high-rise residential building, it is the sum of the floor area of each floor. The calculation of floor area is more complicated.

The meaning is as follows:

The floor area refers to the sum of the horizontal projection area within the perimeter of the exterior wall (or external column) of each building building. When buying a house, you must know the size of the house, especially the floor area. Generally speaking, the construction area refers to the sum of the plane area of each floor measured by the outer horizontal plane of each floor above the foot of the external wall (column) of the building, including balconies, basements, outdoor stairs, etc.

The usable area refers to the area of the usable space of the house in the suite, which is projected horizontally. Generally speaking, the area that people see when they look at a house is the floor area, but it is not the usable area. Generally speaking, the floor area in the suite, the usable area in the suite, the wall area in the suite, the balcony area, and the usable area is the usable area in the suite.

The specific content of the building area includes:

1. Elevator shafts, stairwells, garbage chutes, substation rooms, equipment rooms, public foyers, aisles, guard rooms and other common building areas that serve the whole building.

2. Half of the projection area of the partition wall and the exterior wall between each household and the common building space. Basements that cannot be included in the common construction area include basements used as civil air defense projects, underground garages with separate functions, warehouses, and houses for self-operation and self-use by sales units.

The usable area can be understood literally as the area actually used by the householder. The professional term refers to the sum of the net area directly used for production or living in the plane of each floor of the building, and the construction area is greater than the usable area, which is the area occupied by the wall on the basis of the usable area. In technical terms, it refers to the sum of the plane area of each floor measured above the outer horizontal plane of the outer wall of a residential building.

The construction area is equal to the construction area in the suite + the shared area. The shared area is equal to the construction area of the shared factor. The pooling factor is equal to the total pooled area of the building and the total floor area of the building.

It is one thing to clarify the formula for calculating the floor area of the house, but the developer usually marks the floor area and the area of the suite on the floor plan, so it is more important for buyers to understand the difference between the floor area of the house and the area of the suite, so as not to overpay the house and not enjoy the space it deserves.

The building area is large, and the usable area is small, because the construction area is the area of the public goods that includes the elevator and stairs, plus the area of the house, and the oak state is the construction area. The saleable area is simply the size of the inside of your house. Beam wide shelter.

The floor area is larger than the floor area.

The construction area refers to the sum of the plane area of each floor measured by the perimeter line of the exterior wall of the residential building, and the floor area refers to the horizontal projection area of the land occupied or used by the building area, which is generally calculated according to the ground floor area. Therefore, the total construction area of general commercial housing is much larger than the total floor area.

As a technical and economic index, the construction area is used in various fields of construction projects, and it is also one of the important indicators of national macroeconomic control. The construction area refers to the physical quantitative index of the horizontal area of the periphery of the building structure calculated in square meters, which is a technical parameter that reflects the scale of the building, and it is a basic indicator in the real estate market, becoming the core data that developers and buyers are most concerned about.

1. The concept is different: the construction area refers to the peripheral horizontal projection area of each floor above the foot of the external wall of the house, including balconies, corridors, basements, outdoor stairs, etc.; The right-of-use area refers to the total usable space area of the house, which is calculated according to the horizontal projection of the interior wall of the house, which is commonly referred to as the carpet area or floor tile area.

2. The calculation method is different: the construction area is composed of the construction area in the suite and the shared construction area, and the construction area in the middle suite is composed of the usable area in the suite, the wall area and the balcony area in the suite; The total usable area of each room.

3. The size of the area is different, the area of the building area is larger than the area of the right of use, and the area of the right of use is part of the construction area.

The difference between floor area and usable area is that the concept is different and the calculation method is different.

1. The concept is different

The construction area refers to the peripheral horizontal projection area of each floor above the foot of the external wall (column) of the house, including balconies, corridors, basements, outdoor stairs, etc., and has a permanent building with a cover, a firm structure, and a floor height (inclusive). The usable area refers to the sum of the net area directly used for production or living in the floor plan of the building.

2. The calculation formula is different

Floor area = effective area + structural area = usable area + auxiliary area + structural area; Usable area = building area - structural area - auxiliary surface.

How to Calculate Floor Space for Residential Use:

1. Calculation of the usable area of the sloping roof: when using the sloping roof as the use of the room, in addition to the necessary sanitary conditions (defecation, lighting, ventilation), two conditions should be met at the same time before it can be included in the usable area: the net height of the room used should not be lower than inclusive); More than half of the net area of the room to be used shall not be less than square meters (inclusive).

2. Calculation of the usable area of the balcony: the usable area of the closed balcony is calculated according to its net area; Balconies that are not enclosed are calculated as 1 2 of the net area of the usable area.

3. Calculation of the usable area of the door opening and wall: the usable area of the inner door opening larger than the meter (inclusive) should be calculated according to its projection. The active cabinet should be included in the usable area; The cross-sectional area of the wall is calculated from the ground, and if its net height exceeds meters, the usable area shall be calculated according to its projection.
