# What is the difference between floor area and building area

3) Generally, the building area is not calculated for buildings with storey height less than 2.20M

.

Although the difference between the floor area and the building area is only two words, it is mainly the floor area of buildings at the ground level

.

Copyright note: thank the original author for his hard work, such as

.

There were few buildings with two or more floors, so the floor area of houses was larger than the building area

.

For example, if the whole house has 30 floors, then it is a building Multiply the area of the floor by 30

.

2) structural area: the area occupied by the overall frame of the building, such as the wall and column structure

.

Therefore, the building area of the house is far larger than the floor area

.

4) use function of building area: for the use of building area, I believe developers will have their own division considerations, such as the building area of residential function, commercial function, industrial function and office function

.

The difference between the building area and the floor area: in the past, houses were mainly bungalows and tile roofed houses

.

Now the gap between the two is widening: the building area of houses mainly refers to the floor area from the bottom to the top floor

.

Building area classification when we classify the purpose of building area, it can be divided into the following categories: 1) use area: the use area is mainly the net area of people’s life, which is the product of people competing to buy

.

If the floor height is 2.20M or above, the total area will be calculated, otherwise, only 1 / 2 of the total area will be calculated

.

The calculation principle of building area in the calculation of building area, in case of relevant circumstances, the following principles shall be followed: 1) calculate the total building area of the house with fully closed top cover or the bottom floor with top cover, column and enclosure

.

Building area calculation method building area is an important index to determine the scale of construction, building area calculation is also very complex, not only more provisions, but also professional and technical requirements are very strong

.

3) Building area of complete set of houses: the building area occupied by house users alone, and the shared public building area shared by some elevator wells, pipe wells, stairs, etc

.

Let’s take a look at the calculation method of the building area of single-storey and multi-storey buildings: 1) the building area of single-storey buildings: this area should be calculated according to the external horizontal area of the structure above the external wall plinth, for example, the full area should be calculated when the height is more than 2.20M, and only 1 / 2 of the full area should be calculated when the height is less than 2.20M

.

2) The calculation is generally half of the building area of unsealed houses and parts

.

2) The building area of multi-storey buildings: the first floor is calculated according to the horizontal area of the structure above the external wall plinth, while the second floor and above shall be calculated according to the horizontal area of the external wall structure
