How to calculate the area of the house, how to calculate the area of the house

The calculation rules for the area of the house are: the floor area of the commercial building (sales area) = the shared area + the construction area of the suite. Where:

The shared area is calculated as equal to half of the horizontal projection area of the public foyer and aisle plus elevator shaft plus exterior wall plus stairwell, etc. "You can think of it as half of the thickness of the exterior wall as the area inside the suite, and the other half as the shared area. How to calculate the usable area of the house in the house suite, it is also composed of these three parts:

The usable area, wall area, and balcony construction area, that is, the usable area of the house is part of the building area of the house suite. 1. The calculation of the usable area of the house should be based on the following conditions: the usable area of the house includes a large number of areas, including toilets, storage rooms, halls, corridors, 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 set:

If your house is a new dwelling, then there are some maintenance or load-bearing walls around the space in each unit, including both public 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 floor area:

The original design of the enclosed balcony, then it is also calculated according to the peripheral 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 basisArticle 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 house in the suite (unit) shall be calculated according to the method specified in the "Code for the Design of Residential Buildings". 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 "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 wall area in the suite + the balcony construction area.

Building area = building area in the suite + shared area.

The floor area of the building refers to the sum of the horizontal projection area of the periphery of the outer 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.

Generally speaking, the area of the house mainly refers to the measured area of the house, that is, the peripheral horizontal projection area of the outer wall (column) of the house above the foot, which has a direct relationship with the practical area and utility rate calculation of the house.

Although they are now high-rise residential buildings, most of the houses are single-storey buildings, and the floor area is calculated based on the area of only one floor, including the outer horizontal area above the corner of the building's exterior wall.

The floor height of the house, the floor height (height) of the house with the calculation of the construction area should be above the meter (including the meter, the same below).

If the exterior wall of the outer wall on the same floor has both the main wall and the glass curtain wall, the construction area shall be calculated according to the main wall, and the wall thickness shall be calculated according to the thickness of the main wall.

Metal curtain wall and other material curtain wall, with reference to the relevant provisions of the glass curtain wall, slope structure roof roof roof for slope structure roof (slope roof), the floor height (height) of more than one meter to calculate the construction area. Irregular enclosure. The usable area of the house refers to the total usable space area of the house, which is calculated according to the horizontal area of the interior wall of the house.

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.

When buying a house, the first thing to do is to figure out how to calculate the area. How do you calculate the size of the house? PChouse will take you to find out.

The calculation of the area of the house is the length multiplied by the width. Generally, houses are calculated according to the floor area. The construction area includes the area of the suite and the shared area, of which the area of the suite can be calculated directly by multiplying the length by the width.

The shared area contains more content, and the calculation is generally calculated according to the shared rate.

The area of property right registration generally includes two parts, the area within the suite and the shared area, and the construction area also includes the area within the suite and the shared area, but the property right area and the construction area are not necessarily equal. Because the property right area refers to the floor area of the house where the property owner has the right to the house in accordance with the law, it is recorded in the property right certificate and is determined by the real estate department of the municipality, city and county.

The measurement of the area of the house is the size obtained by measuring the interior of the room, which is the size of the axis of the room minus the thickness of the wall and the thickness of the plaster, and cannot be used as the size in the area. In other words, the area calculated from this size is not the usable area. The usable area is calculated based on the axis dimensions minus the dimensions of the interior of the room where the thickness of the structure is removed.

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).
