Is there a hole in the air above the living room considered a construction area?

Floor area is a real estate term, which is directly related to the calculation of usable area and utilization rate. 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.

The construction area is also known as the construction area, which refers to the plane area of each floor measured above the outer horizontal plane of the external wall of the residential building. It is an economic indicator that indicates the size of a building. The floor area of each floor is calculated according to the horizontal section of the outer wall enclosure above the foot of the building.

It consists of three items, namely the usable area, the auxiliary area, and the structural area. In Chinese mainland, the regulations relating to floor area include the Rules for the Calculation of the Area Sold of Commercial Housing and the Apportionment of Common Area and the current Rules for the Calculation of the Area of Floor Area. In Hong Kong, China, the calculation of gross floor area and usable area is subject to the Code of Practice on Measurement issued by the Hong Kong Institute of Surveyors.

In Taiwan, there are technical building regulations, and Chapter 9 of the building regulations are about the floor area ratio and floor area regulations.

According to the rules for calculating the floor area, the empty part above the living room is not counted as the floor area.

There is an air conditioner above the living room on the outer frame, of course, it is not considered the floor area, because the projection of your air conditioner is also within the scope of the room.

It must be considered the construction area, and the hole is designed to have a certain design plan.

Of course, it doesn't count, how much is the area of an empty hole.
