The usable area of the suite is the amount of the floor area of the suite

Built-up area within the suite.

The built-up area of a commercial house refers to the sum of the usable area, the built-up wall area and the balcony floor area of a complete set of commercial buildings (units). The construction area in the suite is not equal to the carpet area, which is completely private owned by the buyer; Compared with the usable area of the suite, it can more completely reflect the property rights of the buyer's personal private part.

The formula for calculating the floor area of the suite is as follows:

The construction area in the suite = the usable area in the suite + the wall area in the suite + the balcony construction area.

The usable area of the suite.

The usable area of the house in the suite is the area of the usable space of the house in the suite, which is calculated according to the following provisions:

1) The usable area of the suite is the sum of the space area of the bedroom, living room, corridor, kitchen, bathroom, storage room, wall cabinet and other spaces in the suite;

2) The staircase in the suite is included in the usable area according to the sum of the area of the natural floor;

3) Chimneys, ventilation ducts, and pipe wells that are not included in the structural area are included in the usable area;

4) The thickness of the interior wall decoration is included in the usable area.

The area of the wall inside the set.

The area of the wall in the suite refers to the area occupied by the maintenance or load-bearing wall around the use space in each suite of the commercial house. The interior of the commercial house is divided into two types: shared wall and non-common wall. The calculation method of the area of the wall in the commercial house is as follows:

1) The common wall includes the separation wall between the sets, the separation wall between the sets and the projection area of the common building space, and the external wall (including the gable); Half of the horizontal projection area of the shared wall is included in the area of the wall in the suite.

2) The horizontal projection area of the non-common wall is all included in the area of the wall in the suite.

Balcony floor area in the suite:

According to the Rules for Calculation of Floor Area, the floor area of the balcony in the suite is calculated according to the horizontal projection area between the perimeter of the balcony and the exterior wall of the house.

Among them: (1) the original design of the enclosed balcony, according to its peripheral horizontal projection area to calculate the construction area;

2) Pick the balcony (bottom balcony) and calculate the construction area according to half of the horizontal projection area of the bottom plate;

3) The construction area of the concave balcony is calculated as half of its net area (including the area of the baffle wall);

4) For the half-lifted and semi-concave balcony, the construction area of the protruding part shall be calculated according to half of the horizontal projection area of the bottom plate, and the construction area shall be calculated according to half of the net area of the recessed part.

The construction area of the suite is composed of the following three parts: the usable area of the suite + the area of the wall in the suite + half of the balcony construction area.

The exact proportions depend on the size of your house and the size of your balcony.

The specific area should be measured according to the professional surveying and mapping team, and the general individual quantity is not accurate.

To put it simply:

1. The construction area in the suite is: the construction area including the usable area, the area of the inner wall, half of the area of the exterior wall and half of the area of the sub-household wall.

2. The usable area is: the area of the suite that can be used by you, and it does not include the area occupied by the interior wall and the exterior wall. It is the sum of the net usable area of your kitchen, dining room, living room, bedroom, etc.

The area of the suite, the full name of the floor area of the suite. According to the real estate surveying specifications and the detailed rules of surveying and mapping of various provinces, the area in the suite = the usable area in the suite + the area of the wall in the suite + the balcony area.

The usable area of the suite is simply the total area of bricks after the floor of the whole house is completely paved with bricks.

The wall area of the suite is the partition wall area of each room in the suite + the half-wall area of the inner side of the axis of the whole house, and the balcony area (including the so-called entrance garden, sky garden, etc.) is difficult to say.

There are several common situations:

1. For unenclosed balconies, half of the horizontal projection area of the upper cover in the enclosure structure shall be calculated. If the horizontal projection area of the upper cover is less than one-half of the area in the enclosure structure, the balcony area shall not be calculated. If the top cover spans more than one natural floor, the balcony area is not counted (meaning that the lid of your balcony is located on the upper floor floor of your house).

2. The area of the closed balcony is fully calculated. Closure refers to the use of permanent materials approved by the planning department to completely separate the interior and exterior spaces. The usable area in the suite refers to the actual usable area of the room, excluding the structural area such as walls and columns.

The calculation of the usable area shall comply with the following provisions:

1. The indoor usable area is calculated according to the size of the inner surface of the structural wall, and the wall has a composite thermal insulation and thermal insulation layer, which is calculated according to the size of the inner skin of the composite layer;

2. Chimneys, ventilation ducts, various pipeline shafts, etc. are not included in the usable area.

3. Non-public stairs (including stairs in the suite in duplex dwellings) shall be included in the usable area according to the sum of the usable area of the natural floors;

4. The usable area of the residence includes bedrooms, living rooms (halls), kitchens, toilets, dining rooms, halls, corridors, front rooms, storage rooms, wall cabinets, etc.;

5. Usable area coefficient in the suite: When the area of the house is calculated according to the set (unit), the usable area coefficient is the ratio (%) of the usable area in the suite and the building area in the suite plus the common building area that should be apportioned according to the regulations

The usable area in the suite is equal to the construction area in the suite minus the projection area of the wall, which is the actual usable area.

The usable area in the suite is less than the floor area in the suite, and the floor area in the suite is less than the floor area.

The difference between the indoor usable area and the usable area in the suite is that the usable area in the suite is the total area of the bricks after the floor of the whole house is paved, and the absorption is the area next to each room in the suite plus the half-wall area inside the axis of the whole house, which is summarized in this way. The indoor usable area is calculated according to the surface size of the structural wall, which has a composite thermal insulation layer.

The floor area of the suite and the usable area of the suite are not the same, and the definition of the two is as follows.

The floor area of the suite: the sum of the usable area, balcony area and wall area of the suite, which refers to the area of the usable space of the house in the suite, calculated by the horizontal projection area. It is composed of three parts: the usable area of the house, the wall area of the suite, and the floor area of the balcony in the suite.

Usable area in the suite: The usable area in the suite is the sum of the usable area of each room, and the actual usable area of the room, excluding the structural area such as walls and columns. The sales of commercial housing are calculated based on the construction area, and the sales area of the commercial housing (construction area) = the construction area in the suite + the common construction area apportioned.

The full name of the area in the suite is the construction area in the suite, which is composed of the following three parts: the usable area in the suite + the wall area in the suite + the balcony construction area. Selling a house, if calculated by the area of the suite, has certain favorable factors for both the owner and the developer.

For the owner, the way of selling according to the area of the suite is more intuitive, more transparent, and easier to operate. As long as he has a little mathematical knowledge, he can calculate, and the difference is not too big. Then the calculation of the floor area is more complicated, and professional personnel are required to do this.

Historically, most local residential sales have been based on floor area, rather than the floor area of the unit. It is precisely because of this that in the process of residential sales, it is easy for developers to deliberately increase the shared floor area that buyers should bear, and carry out area fraud on buyers, damaging and infringing on the interests of buyers.

However, even if the buyers feel that the shared public floor area does not match the actual situation, it is difficult to measure it on their own and obtain valid evidence, so they can only consider themselves unlucky and have no choice but to endure the exploitation of the developer. Or it can lead to real estate disputes and social conflicts.

Resources.

It refers to the area that can be used indoors, excluding the area of walls, columns and other structures. The calculation of the usable area shall comply with the following provisions:

1. The indoor usable area is calculated according to the size of the inner surface of the structural wall, and the wall has a composite thermal insulation and thermal insulation layer.

Calculation of laminated endothelial size;

2. Chimneys, Tongfeng roads, and various pipeline shafts are not included in the usable area.

3. Non-public stairs (including stairs in the suite in duplex dwellings) shall be included in the usable area according to the sum of the usable area of the natural floors;

4. The usable area of the residence includes bedrooms, living rooms (halls), kitchens, toilets, dining rooms, halls, corridors, front rooms, storage rooms, wall cabinets, etc.;

5. Usable area coefficient in the suite: When the area of the house is calculated according to the set (unit), the usable area coefficient is the ratio (%) of the usable area in the suite and the building area in the suite plus the common building area that should be apportioned according to the regulations

The building area of the complete house is composed of three parts: the usable area of the house, the wall area of the house, and the balcony construction area of the house.

The building area is the area of the house with the pool, the floor area in the suite is the area where the pool is removed, and the usable area is the area of tiles or carpets, and the area occupied by all the walls in the house is removed. Generally speaking, these three concepts are based on area. Of course, there is also the shared area, the capacity area, etc. are not in the scope of your consideration

The area in the suite is the usable area in the suite, and the building area is the area in the suite plus the area of the shared part, such as the apportionment of public spaces such as stairwells, walks, and front rooms.

The usable area of the house in the suite refers to the usable area of the house in the suite, which is calculated according to the following provisions based on the horizontal projection area: (1) The usable area in the suite is the sum of the space area of the bedroom, living room, hallway, corridor, kitchen, bathroom, toilet, storeroom, closet, etc.; (2) The staircase type in the suite is included in the usable area according to the total area of the natural floor; (3) Chimneys, ventilation pipes, and tube wells that are not included in the structural area shall be included in the usable area; (4) The thickness of the interior wall decoration and repair is included in the usable area.

1. The area is different.

The floor area of the suite refers to the area of the usable space of the house in the suite, and the usable area of the suite refers to the area that can actually be used indoors.

2. The composition is different.

The construction area of the suite is composed of three parts: the usable area of the house in the suite, the wall area of the suite, and the construction area of the balcony in the suite.

The usable area of the suite does not include the structural area such as walls and columns. Non-public staircases (including in-suite staircases in duplex dwellings) are included in the usable area according to the sum of the usable area of the natural floors; The usable area of the residence includes bedrooms, living rooms (halls), kitchens, bathrooms, dining rooms, hallways, corridors, front rooms, storage rooms, wall cabinets, etc.

3. The area calculation is different.

The floor area of the suite is calculated based on the horizontal projection area. The construction area in the suite = the usable area in the suite + the wall area in the suite + the balcony construction area. The floor area of the balcony in the suite (GB T50353-2013) is calculated according to the horizontal projection area between the balcony perimeter and the exterior wall of the house1 2.

The usable area of the suite includes the total usable area of bedroom, living room (hall), dining room, kitchen, bathroom, hallway, aisle, storage room, wall cabinet, etc.

The area inside the suite, the full name of the building area in the suite, is composed of the following three parts: the usable area of the set of Zhenghu + the area of the wall in the suite + the construction area of the balcony.

The floor area, also known as the floor area, refers to the sum of the floor area of each floor measured by the perimeter of the exterior wall of the residential building. It is an economic indicator that indicates the size of a building. It consists of three items, namely the usable area, the auxiliary area, and the structural area.

Floor area = area in the suite + shared area, shared area: the area of each beach is the product of the construction area of the respective suite and the apportionment coefficient. Divide the common floor area by the sum of the floor area of each set of the whole building, and finally obtain a common floor area apportionment coefficient of the building.

1) Single-storey buildings, regardless of their height, are calculated as one floor, and their floor area is calculated according to the outer horizontal area above the foot of the building's exterior wall. Single-storey dwellings with partial floors (e.g. attics) should also be counted as gross floor area.

2) The construction area of a multi-storey or high-rise residential building is calculated according to the sum of the floor area of each floor, and the ground floor is calculated according to the outer horizontal area above the foot of the external wall of the building, and the second floor or above is calculated according to the outer horizontal area of the external wall.

3) The construction area of the basement, semi-basement, etc. and the imitation entrance and exit of the corresponding hall shall be calculated according to the horizontal area of the outer wall of its upper mouth (excluding the light well, moisture-proof layer and its protective wall).

4) use the deep foundation to make the underground overhead layer to be used, and the floor height exceeds the meter, and the construction area is calculated according to half of the horizontal area of the overhead layer periphery.

5) The passage through the building, the entrance hall and hall in the building, regardless of the height, are calculated as the floor area. The construction area of the corridor in the hall is calculated according to its horizontal projection area.

6) The construction area of elevator shafts, lifting wells, garbage chutes, pipe shafts and attached wall chimneys are calculated according to the natural layer of the building.

7) The technical floor in the residential building (for placing various equipment and for repair and maintenance), if the floor height exceeds one meter, the construction area shall be calculated according to the horizontal area of the outer periphery of the technical floor.
