How do you calculate the size of your house?

I know a little bit about it! In fact, I was also very entangled before, and then I asked some knowledgeable friends to understand it, and now I share it with you The building area of the suite includes three parts, the wall, the usable area, and the balcony area. The wall area is the sum of all the areas of the non-public wall and half of the horizontal projection area of the public wall.

The usable area is the sum of the interior area of the bedroom, kitchen, bathroom, hallway, etc. If the balcony is enclosed, it is measured according to the perimeter. According to the calculation method mentioned above, the formula for calculating the area in the sleeve is:

The construction area in the suite = the usable area in the suite + the wall area in the suite + the balcony construction area. That's about it! Hope it helps!

If you think I'm good, you can give me a thumbs up! ~

How should the area of the house be calculated?

Housing area = area in the suite + shared area; The area inside the suite = half of the exterior wall + the usable area; Pooled area = pooled coefficient * area in the suite; Pooling coefficient = the common usable area of the whole building The suite area of the whole building; The common area is the part that is shared by the entire building.

1. What is the allocation of land use right area used for?

The area of apportioned land use rights refers to the area apportioned by the landowner or land user in the area of common land, which is marked on the land certificate. The apportioned area refers to the floor area of the common part of the whole building jointly owned by the property owner of the whole building, which is marked on the real estate certificate. The two do not mean the same thing.

Calculation method: 1. The area of the apportioned land use right of the house The floor area of the building The total floor area of the building The floor area of the building. 2. Apportioned area = apportionment coefficient of the construction area in each set.

Apportionment coefficient = the sum of the common area to be apportioned and the sum of the floor area of each suite.

Second, the state stipulates that the difference between the design area of commercial housing and the actual area is a normal value.

It is normal for the area error ratio to be within 3% of the absolute value. The construction area includes the shared area, the multi-storey room rate is generally about 82%, the difference between the construction area and the use area is about 18%, the high-rise is about 75%, the difference between the construction area and the use area is about 25%, because the high-rise elevator and the hall area on the first floor are shared, so the shared area is larger.

3. How to calculate the area of the rented shop.

The calculation method of the area of the rented shop is: the pooling coefficient = the pooled area divided by the area in the suite, and the area in the suite is equal to the construction area minus the pooled area. At present, the state has no clear legal provisions on the area of shops.

Generally, the shared area of shops is larger than that of residential buildings, which is for fire protection reasons, and the other aspect is because there are more stairs and walkways and even patios for shops. From a certain point of view, the level of the shop sharing coefficient also means that the shopping environment is good or bad, which will have different effects on the operation of the shop.

The public sharing coefficient of the shop has a direct impact on the capacity of the consumer group and the first volume of the consumer group. The space area of the shopping mall is limited, and the smaller the pool, the less space for consumers to move, so that the amount will be limited, which will affect the business effect of the shop.

Article 6 of the Rules for the Calculation of the Sales Area of Commercial Housing and the Apportionment of the Common Building Area.

The floor area of the suite is composed of the following three parts:

1. The usable area in the set (unit);

2. The area of the inner wall of the set;

3. Balcony construction area.

Article 8. The common floor area consists of the following two parts:

1. The construction area of elevator shafts, stairwells, garbage chutes, substation rooms, equipment rooms, public foyers and aisles, basements, guard rooms on duty, and other public buildings and management rooms that serve the whole building;

2. Half of the horizontal projection area of the partition wall between the set (unit) and the common building space and the external wall (including the gable).

Generally, it is calculated according to the area of the property certificate. The carpet area of your own house (that is, the place where you can paste carpets and floor tiles), plus the area occupied by building components such as columns and walls, plus the public area shared equally by each household such as corridors, elevator rooms, equipment floors, etc., is considered to be the construction area, and according to different types of houses, the area calculation of the balcony is also different, and the balcony of some houses is only half of the area. And the usable area is almost the carpet area (that is, the area where your own energy comes out).

Calculate the range of the total floor area:

1. The building area of the house is calculated according to the outer horizontal area of the structure above the foot of the outer wall, and the construction area of the multi-storey house is calculated according to the sum of the construction area of each floor;

2. The indoor net height of false floors, loft (dark) floors and inclined structure roofs is above (including the part, calculated according to its projection area;

3. The ceiling height of the house is above (including the stairwell, elevator machine room, calculated according to the peripheral horizontal projection area of the structure;

4. In the ground floor, mezzanine, basement and independently built bicycle room and garage, the floor height is above (, calculated according to the peripheral horizontal projection area of the structure;

5. If the glass curtain wall is used as the exterior wall of the house, it shall be calculated according to the horizontal projection area of its periphery. If it is not used as an exterior wall and is only decorative, it is calculated according to the horizontal projection area of the periphery of the early spike of the structure;

6. For houses with expansion joints, if they are connected with the interior, the expansion joints shall calculate the construction area;

7. The outdoor staircase with a roof is calculated according to the horizontal projection area of each floor;

8. The balcony and corridor that are fully enclosed by the floor and the model are calculated according to the peripheral horizontal projection area of the structure;

9. The part of the void floor in the duplex and duplex building, regardless of the height of the floor, is calculated as the floor area. Stairwells are not recognized as overhang floors.

When you buy a house, the first thing you consider is the area of the house, in fact, the area of the house is what everyone calls the square. So, how do you calculate the square of a house? Let's find out together!

1. How to calculate the square of the house.

The square of the house is calculated as follows: 1. The total number of square meters obtained by the length of the bedroom multiplied by the width; 2. The total number of square meters obtained by the length of the living room by the width; 3. The total number of square meters obtained by the length of the toilet multiplied by the width; 4. The total number of square meters obtained by the length of the kitchen multiplied by the width, add all the numbers. Measure the total area of the corridor and divide this number by the number of floors to get the common area.

Subtracting the common area from the total area of the house is the area of the house.

2. The formula for calculating the area of the house.

1. The usable area in the set (unit);

The dwelling is calculated according to the method specified in the Code for the Design of Residential Buildings (GBJ96-86). For other buildings, it shall be calculated in accordance with the method specified in the special building design standards or in accordance with the Code for the Design of Residential Construction.

2. The area of the wall in the set.

There are two types of maintenance or load-bearing walls around the use space in each set (unit) of commercial housing: shared walls and non-shared walls. The partition wall between each set (unit) of the commercial house, the partition wall between the set (unit) and the common building space and the external wall (including the gable) are all shared walls, and half of the horizontal projection area of the shared wall is included in the area of the wall in the suite. The horizontal projection area of non-shared walls is included in the area of the wall in the suite.

3. Balcony construction area.

The calculation shall be carried out in accordance with the current national "Building Area Calculation Rules".

4. The construction area of the suite.

The area of the house = the usable area of the suite + the area of the wall in the suite + the balcony construction area of the house is the area of the house including the shared area and the floor area of the suite, and the area of these two parts can be calculated by formula.

The area of the house is calculated according to the square, and the formula for calculating the square number of the house is generally the length of the room multiplied by the width of the room, for example, the length of the house is 8 meters, and the width of the room is 5 meters, then the square number of the room is 8 5 = 40. However, developers generally indicate the floor area of the house and the usable area of the suite on the floor plan, so the buyer should understand the calculation method of the floor area of the house and the area of the suite.

Article 14 of the Interpretation of the Supreme People's Court on Several Issues Concerning the Application of the Law of the Corporation in the Trial of Cases Involving Disputes over Contracts for the Sale and Purchase of Commercial Housing Article 14 If the floor area of the housing suite or the floor area of the house delivered by the seller is inconsistent with the area agreed in the contract for the sale and purchase of commercial housing, and there is an agreement in the contract, it shall be handled in accordance with the agreement; If there is no agreement in the contract or the agreement is not clear, it shall be handled in accordance with the following principles: (1) If the absolute value of the area error ratio is within 3% (including 3%), and the settlement is based on the facts in accordance with the ** agreed in the contract, and the buyer's request to terminate the contract shall not be supported; (2) If the area error exceeds 3% of the absolute value, and the buyer's request to terminate the contract and return the purchase price and interest paid shall be supported.

1. The formula for calculating the square area of the house.

1. The area of the house is calculated according to the square, and the formula for calculating the square number of rooms is generally the length of the room multiplied by the width of the room, for example, the length of a room is 7 meters, and the width of the room is 4 meters, so the square number of the room is 7 4 = 28. However, developers generally indicate the floor area of the house and the usable area of the suite on the floor plan, so the buyer should also understand the calculation method of the floor area of the house and the area of the suite.

2. How to measure the area of the house.

1. First of all, the self-residence and other houses, the common part of the junction is divided first, the total area between the lines is the total construction area of the residence, the calculation method, one is to add the total usable area plus the layout area of each section of the wall, and the other is to directly calculate the area of the geometric figure enclosed by its own axis, but the total construction area of the residence is generally not remarked in the drawing.

2. The balcony area is relatively easy to measure, limit the balcony area to the actual projection area, the owner can measure along the edge of the peripheral building at that time, and then take half of the total area as the actual property right area of the balcony.

3. The house plan obtained by the owner is a standard size drawing, and the marked size position refers to the core position of the wall organization, that is to say, the core position of the wall height and thickness of the banquet, and the owner can not directly compare the space size with the design drawings when measuring on the spot, so that there will be a wall thickness error more than sure, for example, the size length of the house plan is meters, but the actual measurement size is 12 meters, then the wall thickness is meters, then the actual size is meters, If you say that in the calculation of the area, you should add two silver side wall wall thickness is meters, and the public wall can only calculate half of the wall thickness.

4. Therefore, measuring the interior is the first step in decoration, and it is better to carry out decoration construction when the size of the room is known.

Legal analysis: The calculation rules are: the floor area of the commercial building (sales area) = the floor area in the suite + the shared area.

Among them: shared area = elevator shaft + stairwell + public foyer and aisle + half of the horizontal projection area of the exterior wall, etc. "Half of the horizontal projection area of the exterior wall" is simply understood, that is, half of the thickness of the exterior wall is counted as the inner area of the suite, and half is counted as the shared area.

Legal basis: "Rules for the Calculation of the Sales Area of Commercial Housing and the Apportionment of the Common Construction Area" Article 6 The construction area of the suite is composed of the following three parts:

1. The usable area in the set (unit);

2. The area of the wall in the set.

3. Balcony construction area.

The construction area in the house suite is also composed of these three parts: the usable area, the wall area, and the balcony construction area, that is, the usable area of the house is part of the building area in the house suite. 1. The calculation of the usable area of the house should be carried out under the following conditions:

It includes a lot of usable area of the house, including toilets, storage rooms, halls, corridors, closed kitchens, bedrooms, living rooms, toilets, false floors, wall cabinets, etc. If your house is a duplex dwelling, then add up the area of the stairs in the house according to the area of the natural floor. It is not included in the area of the structure, such as chimneys, ventilation ducts, etc.

2. Calculation of the area of the wall in the suite: If you are a new house in the house, then there are maintenance or load-bearing walls around the space in each suite, including its public walls and non-public walls. For example, the free wall in the set is included in the area of the wall in the set according to the horizontal projection area.

3. Calculation of balcony construction area: The original design of the closed balcony also calculates the construction area according to the outside horizontal projection area. The balcony (bottom balcony) is calculated according to half of the horizontal projection area of the bottom plate.

The concave balcony is calculated according to half of the net area (including the wall area). If it is a half-raised and half-concave balcony, then its protruding part is also calculated according to half of the horizontal projection area of the bottom plate, then its recessed part is calculated according to half of the net area.

Legal basis. Article 7 of the Rules for the Calculation of the Sales Area of Commercial Housing and the Apportionment of the Common Building Area The calculation principles of each part of the building area in the suite are as follows: 1. The usable area of the residential house in the suite (unit) shall be calculated according to the method specified in the "Residential Building Design Code".

Other buildings. Calculated in accordance with the method specified in the special building design code or with reference to the "Residential Building Design Code". 2. The maintenance or load-bearing walls around the use space of each set (unit) of the commercial house have two types: common walls and non-shared walls.

The partition wall between each set (unit) of the commercial house, the partition wall between the set (unit) and the common building space, and the external wall (including the gable) are all common walls, and half of the horizontal projection area of the common wall is included in the area of the internal wall of the suite. The area affected by the horizontal projection of the non-common wall is all included in the area of the wall in the suite. 3. The construction area of the balcony shall be calculated according to the current national Songzheng "Building Area Calculation Rules".

4. The calculation of the construction area in the suite is as follows: the construction area in the suite = the usable area in the suite + the area of the wall in the suite + the balcony construction area.
