How to determine the building area of the right to use the house

The construction area of the right-to-use house refers to the sum of the horizontal areas of each floor of the building, including the usable area, the attached area and the structural area. The calculation formula is building area = effective area+structural area = usable area+auxiliary area+structural area = structural area+auxiliary area+usable area inside the suite.

Surveying and mapping standard of building construction area

1, the construction area of all kinds of houses is the sum of the interior construction area of the house or the interior construction area of the unit and the shared area of the house.

2. The building area of the house is the sum of three building areas: the internal use area of the house, such as bedroom, living room, kitchen and children's room; The wall area of the house, including the wall separating the room, the wall separating the residents, the load-bearing wall, etc.; Elevator, staircase, corridor, garbage room, power distribution room, guard and other common parts of the house.

3. The surveying and mapping standard of the internal usable area of the house is: half of the walls with * * * are included in the wall area, and some self-occupied walls without * * * are calculated according to the comprehensive area of the horizontal projection area of the wall; The balcony is fully enclosed, calculated according to the total area of the horizontal projection area, and the balcony is calculated according to half of the projection area; The building area of each room is calculated and added according to the horizontal projection area.

4. Parking spaces, basements, carports and basements used for civil air defense projects in the residential area to which the house belongs are not included in the pool area, because some of these areas are requisitioned or used by profit-making sales individuals or countries.

5. Housing pool area refers to the pool area that belongs to the sum of residents' shared facilities area, including elevator construction area plus staircase construction area plus lobby construction area plus power distribution room construction area. Area calculation is based on horizontal projection area.

What does the interior construction area mean?

The interior construction area refers to the usable area of the interior house, which is calculated according to the horizontal projection area. Generally speaking, the interior construction area consists of three parts: the usable area of the interior house, the interior wall area and the interior balcony construction area.

1. The usable area of the suite mainly refers to the sum of the areas of bedroom, living room, living room, dining room, aisle, kitchen and bathroom. Located at the household door. However, it should be noted that chimneys, ventilation pipes and pipes will not be included in the internal area of the house.

2. The wall area mainly includes * * * with wall and non * * * with wall, and the calculation methods of these two kinds of walls are also different: the horizontal projection area of non * * * with wall is all included in the inner wall area. * * * The wall is included in the interior wall area according to half of the horizontal projection area. In addition, the thickness of the wall inside the house will also be included in the interior wall area.

3. When buying a house, if it is a closed balcony, calculate the construction area according to the horizontal projection area of its periphery. If the balcony is selected, the construction area shall be calculated as 1/2 of the horizontal projection area of the floor. The construction area of concave balcony is calculated as 1/2 of its net area.
