How should the area of the house be calculated?

How to calculate the area of the real estate certificate.

How to calculate the outside area of my house with an interior of 105 square meters.

1.The building area is the horizontal projection area of the outer part of the building. To put it simply, it is length x width, and length and width are the outer dimensions of the house; 2.

If it is a unit with irregular shapes, such as curved balconies, stairwells, elevator rooms, etc., it can be divided into rectangles piece by piece and then calculate the area; 3.The key is that if there are two or more households on one ladder, the common wall part must be half of one person, or multiple people share the wall area. For example, if there are two households on one ladder and the wall is 24cm thick, then each person can share 12cm when calculating the area.

Then there is the shared area, which is the stairwell, elevator room, common corridor, etc. To put it simply, if there are two households on one ladder, the floor area of the floor is 200 square meters, and the house type is exactly the same, then the floor area of your house is 100 square meters, which already includes the shared area.

The area of the house usually refers to the area of the house, that is, the total area of the building chain on the ground. By multiplying the length and width of the front and sides of the house, you can calculate the size of the house. For example, if the front length of a house is 20 meters and the width of the side is 30 meters, then the area of this house is 20 30 = 600 square meters.

Problem description: Calculate the floor area of a house, such as a square or rectangular house, whether the calculation method is to multiply length by width.

Analysis: How is the area of a house calculated?

The Rules for the Calculation of the Sales Area of Commercial Housing and the Apportionment of Common Floor Area (Trial) issued by the Ministry of Construction stipulate that the building area refers to the peripheral horizontal area above the foot of the external wall of the house (the sum of the peripheral horizontal area of each floor for houses with more than two floors), including the construction area of balconies, corridors, outdoor stairs and so on.

The multi-storey and high-rise commercial housing currently on the market is made up of several units (units) in the state. The calculation of the floor area of the new house is based on the unit of the building, and the common area is reasonably apportioned according to the proportion of the building area in the suite, that is, the construction area of each set (unit) is equal to the sum of the construction area in the suite and the apportioned common area. The building area of the suite is composed of three parts: the usable area of the suite (unit), the wall area of the suite and the floor area of the balcony.

The apportionable common floor area is calculated according to the following formula:

Apportioned common floor area Common floor area apportionment factor Floor area within the set of slips Common floor area apportionment factor Sum of common floor area within common building area.

If you pave the floor, then according to the usable area as you say square meters.

The rules for calculating the area of the house are:

The floor area of the commercial building (the area of the slow source in the sales draft) = the shared area + the construction area of the suite.

Among them: 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.

Half of the horizontal projection area of the exterior wall"You can understand it as half of the thickness of the exterior wall, which is counted as the area inside the suite, and half of the other key state will be counted 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 carried out under the following conditions:

It includes a lot of usable area of the house, 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.

The face of the house should be sensitive, how to calculate it.

How do you know how to calculate the amount of the property certificate.

There are many types of house area, each with a different calculation method, how to calculate it in detail? Here I will tell you how the area of the house is calculated. , how to calculate the floor area of the house, the shared area of the house, and the usable area of the house!

1. Calculation of property right area.

The property area of the house refers to the floor area of the house in which the property owner has the ownership of the house in accordance with the law, which is determined by the department of La Youyuan, the real estate administrative director of the municipality, city and county. The property right area of the house is divided into two categories: one is a complete set of residences, and the ** area of the property right of this type of house is equal to the sum of the building area in the suite and the shared construction area; The other type is an independent residence, such as a villa or a bungalow, etc., then the area of the house property right is equal to the value of the length, width and number of floors above the foot of the house.

2. Calculation of usable area.

The usable area of the house is equal to the sum of the horizontal projection area enclosed by the inner and outer surfaces of the walls of each functional space, that is, the indoor carpet area that most people say, which refers to the space area available for use in the sub-household (set) door of the residence in the unit of household (set).

The area used for the collapse of the house includes the bedroom, living room, kitchen, bathroom, indoor walkway, staircase, balcony, basement, attic and other areas used for daily living. If you want to calculate the usable area of the dwelling, you can calculate it by the horizontal projection line of the interior wall of the dwelling.

3. Calculation of construction area.

The construction area of the house refers to the peripheral horizontal projection area of the outer wall (column) of the house above the foot, which is directly related to the useful area and useful rate calculation of the house, which is usually larger than the usable area.

4. Calculation of the shared area.

The shared area of the house is calculated by multiplying the total floor area of the house by the common floor area divided by the sum of the floor area of the suite, and the common floor area sharing coefficient is equal to the sum of the common floor area divided by the floor area of the suite. Generally speaking, the coefficients of commercial housing in residential buildings are about and about, and the coefficients of commercial housing in high-rise residential buildings are about and around.

5. What is the right area for yourself?

In the 80s, the area of two bedrooms was about 50-60 square meters, and now, usually two bedrooms are 80-90 square meters, and some even present a large two-bedroom of 120 square meters. However, in practice, it is not the case that the larger the living area, the better, and the so-called "suitable is the best". Here are two calculation methods:

Type 1: The sum of the family's ages multiplied by square meters. For example, if both husband and wife are 30 years old and the child is 5 years old, the sum is 65 years old, and 6 times is, which means that the appropriate living area is square meters.

The second method: the three-generation calculation method. The couple's rate is 50 square meters, 10 square meters for preschool children, 15 square meters per person for elementary school to high school children, and 20 square meters for university children and white children.

Therefore, consumers can choose a suitable room for themselves according to the practitioners and age of their own families.

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.
