My 144 43 floor area, the indoor area is only 120 1, is it a little too little?

The construction area is divided into usable area and shared area. Your occupancy rate has reached more than 83%, which is quite good.

On the first floor, the walls and so on are on the one hand, and the shared area also includes elevators, stairs, aisles, shafts, etc.

You only buy a house, but the developer builds more than just a house, so each household has to bear some of the shared area.

83%, which is already good. Beijing's Huiyuan Apartment, a 150-square-meter room, with a usable area of less than 100 square meters, who to reason.

Look at how many households your house is, but judging from the above data, it should be one three or four households, and the utilization rate is just a disguise, when they are all large households, the utilization rate will naturally go up, similar to the utilization rate of your home of 83%. Because in general, the core tube area can be controlled fixedly. (The elevator staircase share part, the general situation can be controlled at about 60 70 square meters) There is another situation, that is, the construction area of your home has just exceeded the square, I don't know that your side of more than 144 square meters needs to be defined as a luxury house, if you define a luxury house, the tax rate has risen by another level, hehe

The floor area is divided into two concepts, one is the land area occupied by the house you are buying, such as the walls, etc., and the other is the land area, such as the land area occupied by a real estate, including green space, roads, etc.

The usable area, as the name suggests, is the area you can use, if you buy a house, the area occupied by the wall is what you can't use, except for the area you can't use, it's your usable area, so, the building area is greater than the usable area.

Nowadays, almost all developers will use the floor area to calculate the ** of the house, so the actual size of the house you buy is smaller than the calculation.

Hehe. Of course it's small.

Commercial housing construction.

Bai area.

The building area in the suite + the shared area.

Among them: shared area = elevator shaft + stairwell dao + public foyer and aisle version + half of the projection area of the exterior wall water right.

Half of the thickness of the exterior wall is counted as the area inside the suite, and half is counted as the shared area.

The roof is also considered a shared area. If the roof of the house is a sloped structure (sloping roof), the building surface is calculated for the part where the floor height (height) is more than one meter.

As far as your house is concerned, the construction area of your suite of 109 square meters should not be half of the projection area of the exterior wall, we can estimate that it is 6 square meters, your suite area is 115 square meters, and the shared area is 26 square meters.

So your house shouldn't be a big problem!
