The following

When the height of a commercial building is more than or equal to 5 meters, when calculating the floor area ratio index, the building area is calculated by multiplying the standard floor area by 1.5 times. The building height of large-scale commercial buildings (such as supermarkets, large shopping malls, specialty stores, restaurants, entertainment and other commercial buildings with centralized functions) that reach more than 2,111 square meters can be appropriately increased according to functional requirements.

the height is the vertical distance between the upper and lower floors or between the floor and the ground. That is, the height of a first-floor house.

In the "Modular Coordination Standard for Residential Buildings" issued in 1987, it is clearly stipulated that the parameters adopted for the height of brick-concrete residential buildings are: 2.6m, 2.7m and 2.8m..

In addition to the meter, the height of a house can also be calculated by the floor, and the height of each floor has certain requirements in design, which is called the story height.

the height of a story usually refers to the distance between the lower floor or the floor to the upper floor. The difference between the height of the floor and the thickness of the floor is called the clear height. In order to reduce costs, save building materials, save land and other considerations, the average residential floor height is about 2.8 meters.

the height of an office building is 4.8m or higher. When calculating the floor area ratio index, the building area is calculated by multiplying the floor area by 1.5 times, regardless of whether there is an interlayer in the floor.

The floor area ratio of foyer, lobby, atrium, inner corridor and lighting hall can be calculated according to their actual construction area.
