How to calculate the size of a house per square meter?
When buying or renting a home, calculating the square footage is a crucial step. In particular, the calculation method of "one square meter" is directly related to the price and actual use experience. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the calculation method of house area and provide structured data for reference.
1. Basic concepts of house area

House area is usually divided into three types: building area, apartment area and shared area. Here are their definitions and how they are calculated:
| area type | definition | Calculation formula |
|---|---|---|
| Building area | Including the total area of the apartment and the shared area | Apartment area + common area |
| Inner area | The actual usable area of the house | Wall area + usable area |
| Pool area | Apportioned area of public areas (e.g. elevators, stairs, etc.) | Building area - area inside the apartment |
2. Specific calculation method of one square meter
1.Building area calculation: Developers usually use the building area as the sales area, so home buyers need to know whether the price per square meter is based on the building area or the internal area.
2.Calculation of inner area: When actually living, the area inside the apartment can better reflect the real use value of the house. The following is an example of calculating the area within a sleeve:
| room | Length (meters) | Width (meters) | Area (square meters) |
|---|---|---|---|
| Master bedroom | 4.5 | 3.2 | 14.4 |
| Second bedroom | 3.8 | 3.0 | 11.4 |
| living room | 5.0 | 4.0 | 20.0 |
3.The impact of shared area: The higher the share ratio, the lower the actual housing acquisition rate. The following is a reference for the proportion of public stalls for different building types:
| Building type | Sharing ratio range |
|---|---|
| multi-storey residential | 10%-15% |
| small high-rise residential | 15%-20% |
| high-rise residential | 20%-30% |
3. Hot topic: Controversy over the area of public stalls
Recently, the calculation method of public pool area has become a hot topic again. Many home buyers believe that the shared area is not transparent, resulting in the actual housing acquisition rate being lower than expected. The following are the hot topics of discussion among netizens:
1.Should the shared area be cancelled?: Some experts suggest pricing based on the area within the unit to avoid disputes.
2.The rationality of the share ratio: In some areas, the share ratio is as high as 30%, causing dissatisfaction among home buyers.
3.Developer Responsibilities: Call on developers to clearly disclose the specific composition of the public pool area.
4. How to avoid area calculation traps
1.View the purchase contract: Clearly mark the building area, apartment area and shared area.
2.Field measurement: When closing the house, you can ask a professional agency to measure the actual usable area.
3.Compare surrounding properties: Understand the share ratio of similar properties and avoid exorbitant share share ratios.
5. Summary
The calculation of house area involves multiple dimensions, and home buyers need to focus on the area inside the house and the proportion of shared spaces. The recent controversy over the shared area also reminds us that we should carefully check the contract terms when purchasing a house to ensure our own rights and interests. I hope the structured data and hot spot analysis in this article can provide you with a practical reference!
