How to calculate the area of a cline
In recent years, with the diversified development of the real estate market, loft apartments have become more and more popular among home buyers because of their unique space design and practicality. However, the area calculation method of loft houses is different from that of traditional flat floors, and many home buyers are often confused by this when buying or renovating. This article will combine the hot topics and hot content on the Internet in the past 10 days, analyze the calculation method of cline area in detail, and provide structured data for reference.
1. Basic rules for calculating cline area

A loft house usually refers to a residence divided into two floors, upper and lower, connected by indoor stairs. Its area calculation is mainly divided into the following parts:
| Calculation project | Calculation method | Remarks |
|---|---|---|
| Building area | Including the sum of the projected areas of all floors | Including public parts such as walls and stairs |
| Inner area | The sum of the actual usable areas of each floor | Excludes public stalls |
| Floor height limit | Calculate the total area of the part with floor height ≥ 2.2 meters | The half area is calculated for the part with floor height less than 2.2 meters. |
| Stair area | Calculated according to the number of natural layers | Usually included in the pool |
2. The difference between loft, duplex and LOFT
Recently, there has been a lot of discussion on the Internet about lofts, duplexes and lofts. Although these three house types all involve multi-story space, there are obvious differences in their area calculations:
| House type | Floor height characteristics | Area calculation features |
|---|---|---|
| Cline | Complete two floors, both floor heights meet the standard | Both floors are included in the property rights |
| duplex | Part of the space is used as a mezzanine | Mezzanine area may be limited |
| LOFT | Usually the floor height is 4-5 meters | Calculate building area based on single floor only |
3. Practical cases of cline area calculation
Based on the latest hot discussion on a real estate forum, we compiled the area calculation of a typical loft case:
| Floor | Actual area (m²) | Floor height (m) | Calculate area(m²) |
|---|---|---|---|
| first floor | 85 | 3.0 | 85 (full area) |
| Second floor | 75 | 2.5 | 75 (full area) |
| Loft | 25 | 1.8 | 12.5 (half area) |

4. Things to note when buying a house
In light of the recent hot spots in real estate disputes, special attention should be paid to the following when purchasing a loft house:
1.Verify the area of property ownership certificate: Some developers may include the attic area that does not meet the standard into the property rights, leading to disputes.
2.Understand local policies: Different cities have slightly different calculations of floor area. For example, Beijing stipulates that spaces with a floor height of less than 2.2 meters are not included in the sales area.
3.Measure the actual usable area: Public parts such as stairs and pipe wells will occupy more area, and the actual room acquisition rate may be lower than expected.
4.Pay attention to renovation costs: The cost of decoration such as stair renovation and water and electricity wiring for double floors is usually 30%-50% higher than that for flat floors.
5. Expert advice
According to the latest survey data released by a well-known home furnishing public account:
| Suggested projects | Professional advice |
|---|---|
| Before buying | Request developers to provide strata area details |
| Upon acceptance | Hire a professional surveyor to review the area |
| During decoration | Prioritize safety at stair locations |
| long term residence | Pay attention to the temperature difference between the upper and lower floors |
From the above analysis, it can be seen that the calculation of the loft area involves multiple dimensions. Home buyers must understand the relevant regulations in detail before making decisions to avoid unnecessary disputes in the future. At the same time, as building codes continue to improve, it is recommended to continue to pay attention to the latest local real estate policy changes.
