Formula is expressed as: commercial housing sales area = building area + allocation of public construction area. 1, the construction area consists of the following three parts: the use of units (units) within the area, the wall area, balcony construction area. The calculation principles for each part of the building area are as follows: (1) the usable area of a unit The house shall be calculated according to the method specified in the code for design of residential buildings. Other buildings, According to the method specified in the special building design code or calculated by reference to the code for residential building design.
