How to convert the usable area and the construction area

Building area: The exterior wall (column) of the house is strangled.

The peripheral horizontal projection area of the above floors, including balconies, corridors, basements, outdoor stairs, etc. And it has a permanent building with a cover, a firm structure, and a floor height of more than meters (including meters).

Usable area: the total usable space area of the house, calculated according to the horizontal projection of the interior wall of the house, that is, the so-called carpet area or floor tiles.

Area. Simple conversion formula: usable area * floor area.

Extended information: Floor area, also known as floor area, is a professional term in the construction industry, which is directly related to the calculation of usable area and utility rate. It refers to the sum of the plane area of each floor measured above the outer horizontal plane of the external wall of the residential building, which is an economic index indicating the scale of the building and a physical quantity index that reflects the scale of the building construction in square meters.

The floor area of each floor is calculated according to the horizontal section of the external wall enclosure above the foot of the building, which includes three items, namely the usable area, the auxiliary area and the structural area.

The usable area of a dwelling refers to the sum of the net area of each floor of a building that is directly used for production or living. 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**.

That is, the area inside the suite.

Subtract the area of the wall in the suite, which is the net usable area in the house.

Among them, the area in the suite = the usable area in the suite + the wall area in the suite + the balcony construction area.

Usable area - encyclopedia.

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.

When it comes to the usable area and construction area of the house, many people don't know how to convert and the specific conversion formula when converting. So, let me share with you the conversion of usable area and floor area, as well as the conversion formula.

1. Conversion of usable area and construction area.

1. Usable area = indoor construction area - indoor wall area - balcony area. There is a figurative saying about the usable area in the suite, which is to lay the area on the carpet, how much carpet area can be laid, then how much indoor usable area is. Indoor wall area, the indoor wall area protects the partition wall inside the house, and the partition wall between the two households and the external flushing wall are composed of three parts.

2. Construction area = building area in the suite + shared area. Pooled area = floor area Pooled coefficient. Pooling coefficient = total pooled area of the building Total construction area of the building, construction area in the suite = usable area in the suite + wall area in the suite + balcony area.

2. What is the usable area and construction area.

1. Construction area: It is composed of indoor construction area and shared construction area, and indoor area is composed of indoor use area, wall area and balcony area. Therefore, the construction area includes the usable area, and the construction area is a little larger than the usable area.

2. The construction area refers to the sum of the horizontal projection surface within the exterior wall and periphery of each house. The usable area refers to the usable area of the indoor house, and the construction area of the house is composed of the indoor construction area and the shared area.

3. Usable area: The usable area is the sum of the usable space of each area and the horizontal projection area in the wall. Many people will say that it is the indoor carpet area, which roughly means, except for the part under the door opening, the sub-door can be counted as the usable space area.

4. Including bedrooms, living rooms, toilets, living rooms, corridors, stairs, balconies, basements, attics and other areas, the usable area is calculated according to the horizontal projection line of the residential interior wall.

Article summary: The above is the conversion of usable area and construction area shared for you, as well as the relevant content of the conversion formula, I hope it will be helpful to you. Generally speaking, the proportion of usable area is about 60 or 70 percent of the total area of macro oak.

Hello, the state stipulates that there is a certain ratio, generally speaking, the multi-storey room rate is higher than the high-rise room rate. 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. For example, you can multiply the floor area by the housing rate, and you can calculate your usable area, your house area is 113 square meters, if it is a multi-storey usable area of 93 square meters, if it is a high-rise area, it is about 84 square meters.

Hello, the usable area is the construction area minus the wall area of the suite, generally speaking, the proportion of the usable area accounts for about 60% to 70% of the total area. That is, the difference between the construction area and the use area is generally 15%-35%, that is, the area opening rate, or area benefit rate, that people are concerned about when buying commercial housing. Generally, the area yield of high-rise residential buildings is slightly lower, and the area yield of multi-storey buildings is slightly higher.

You can snap the wall against the drawing.

Floor area Floor area in the suite The difference in the public floor area that should be apportioned. The construction area in the suiteThe usable area in the suite (the net area of the hall, bedroom, kitchen, bathroom, storage, the wall area, the balcony construction area).

Interior wall area of the set: 1 2 Common wall, wall projection area or non-shared wall, horizontal projection area of wall. Common apportionment area, common apportionment area, common building area, apportionment factor, building area in the suite.

Common floor area apportionment factor: Common floor area apportionment factor Common floor area of the whole building The sum of the floor area of each set of the whole building.

In fact, the construction area is the noun of real estate socks, which is directly related to the calculation of the area and utility rate of real and virtual banquets. Depending on the country and region, the definition and measurement standards may not be consistent. The floor area is generally larger than the usable area.

The construction area is an important technical and economic indicator in the field of construction engineering, and it is also one of the important indicators of national macroeconomic regulation and control. The construction area refers to the horizontal area of the outer structure above the foot of the external wall of the building, and is a physical quantity index that reflects the scale of housing construction in square meters.

Equal floor area = usable area *. The usable area of a dwelling includes the sum of the net area within the dwelling. If it is a sloping roof, half of the indoor area must be above the net height, and the rest of the area must be within the positive and negative difference, then it can be called the usable area, and the part of the balcony area with more than 6 is counted as the usable area according to the proportion of half.

Hello, square meters, what is the floor area?

Only more than 40 square meters.

This room of yours should be a semi-room layout.
