What do you mean you don't consider the floor area ratio?

Excluding the building area (excluding the floor area ratio), in short, this part of the building area is not included when calculating the floor area ratio. The underground construction area is included in the total construction area, but it is not necessary to calculate the underground construction area when calculating the floor area ratio, which belongs to the non-capacity area.

The building area that is not included in the plot ratio is conditional, such as the protruding part of the roof, 1/4 larger than the top floor area, which must be included in the plot ratio.

In most parts of the country, basements are not included in the floor area ratio, but there is no linear relationship between the cost of basements and the number of floors in basements. In addition, more floors also bring adverse effects such as traffic problems and the decline in the rate of getting a room. Therefore, the planning is not unlimited, and the basement can be built at will.

Capacity counting area and non-capacity area

Both the calculated capacity and the excluded capacity are aimed at the building area, and the occupied area is two concepts. General logic: plot ratio × plot ratio = building area, but in most cities, underground space is not included in the plot ratio, so there will be a distinction between plot ratio and non-plot ratio. On the premise that the area is relatively certain, whether it is included in the floor area ratio directly affects the size of the building area.

The so-called plot ratio is to calculate the plot ratio. Under normal circumstances:

Calculated plot ratio = planning condition plot ratio × planning and construction land area

Note: The planned construction land area should be equal to or less than the land area of the general plan, and the plot ratio of completed projects can only be equal to or less than the planned plot ratio.
