In the process of buying a house, do you know how to calculate the area of ??a house? The area of ??a house is generally composed of the usable area within the suite, the wall area within the suite, and the balcony building area. However, many home buyers will have such a question, that is, how to calculate the house area based on the floor plan? So, today I will help you clear up this doubt and tell you how to calculate the area of ????the house based on the floor plan? Also talk about how to calculate the usable area of ??a house?

How to calculate the area of ??the house based on the floor plan

Generally speaking, the formula for calculating the area of ??the building in the apartment is as follows: Building area in the apartment = usable area in the apartment + balcony area + wall area . Next, this article will conduct a detailed analysis and introduction to this formula.

Generally speaking, the usable area in a suite refers to the total area of ??the bedrooms, living rooms, halls, corridors, kitchens, bathrooms, toilets, storage rooms, wall cabinets, etc.; a suite Generally speaking, internal stairs can be included in the usable area based on the total area of ??the natural floors; however, these are not included in the chimneys, ventilation ducts, and pipe wells within the structural area. The above areas are included in the usable area; However, the decorative thickness of interior walls can also be included in the usable area.

Generally speaking, the wall area in a suite refers to the relevant area occupied by walls or other load-bearing supports used for maintenance or load-bearing around the use space in the suite. The space between each suite Partitioning walls and suites that separate the building space of the condominium, as well as external walls (including gables) and other related private walls, are calculated into the internal wall area of ??the suite based on half of the horizontal projected area. Generally speaking, all the walls within the suite will be included in the area of ??the wall within the suite based on the horizontal projected area.

Under normal circumstances, the building area of ??the balcony in the suite needs to be calculated based on the horizontal projected area between the balcony periphery and the exterior wall of the house. Among them, the enclosed balcony needs to calculate the building area based on the entire horizontal projection, while the unenclosed balcony needs to calculate the relevant building area based on half of the horizontal projection.

How to calculate the usable area of ??a house

1. Calculation of the usable area of ??the roof: When using a sloped roof as a room, in addition to necessary sanitary conditions (defecation, lighting, ventilation), Two conditions must be met at the same time to be included in the usable area: the net height of the used room should not be less than 1.5 (inclusive); more than half (inclusive) of the net area of ??the used room should not be less than 2.1 square meters (inclusive) ).

2. Calculation of the usable area of ??the balcony. The usable area of ??the enclosed balcony is calculated according to its net area; the usable area of ??the unenclosed balcony is calculated according to 1/2 of the net area; the usable area of ??the door opening and wall is calculated.

3. The usable area of ??an inner door opening larger than 1.5 meters (inclusive) should be calculated according to its projection, and the movable cabinet is included in the usable area; the wall cross-sectional area is calculated from the ground, and its net height For those exceeding 1.8 meters, the usable area will be calculated based on its projection.

Through the above introduction, I believe everyone has some understanding of the two issues of how to calculate the house area based on the floor plan and how to calculate the use area of ??the house. In fact, calculating the area of ????a house based on the floor plan is not the same. It is a very difficult thing to calculate, as long as you understand the relevant calculation formula, it will be easy to calculate. Once you understand the actual area of ????the house, it will not be easy to be deceived by a third party or an intermediary.
