The formula for calculating the area in the suite is: the area in the suite = the usable area in the suite + the area of the wall in the suite + the floor area of the balcony.
Among them, the usable area of the suite refers to the area of the usable space of the house in the suite, including the sum of the space area of bedrooms, living rooms, halls, corridors, kitchens, toilets, toilets, storage rooms, closets, etc., as well as the total area of the indoor stairs according to the natural floors. It does not include the area of internal chimneys, ventilation ducts, pipe wells, etc. in the set included in the structural area, and the thickness of the interior wall decoration is also included in the usable area.
The area of the wall in the suite refers to the area occupied by the maintenance or load-bearing wall around the use space in each suite of the commercial house, including the partition wall area of the indoor room, as well as the area of the half-wall and the balcony area on the inner side of the house axis. Half of the horizontal projection area of the common wall wall is included in the area of the wall in the suite.
The floor area of the balcony varies depending on whether the balcony is closed or not. Enclosed balconies are calculated according to the horizontal projection area of the periphery, while overlaid balconies and concave balconies are calculated according to half of the horizontal projection area.
In short, the area in the suite is composed of three parts: the usable area of the suite, the wall area of the suite and the floor area of the balcony, and it is necessary to pay attention to the calculation methods and regulations of each part when calculating.
