According to China's "General Principles for Civil Building Design" (GB 50352-2019) and related specifications, the classification of high-rise and small high-rises is mainly based on the building height and number of floors. The following are specific definitions:
| Building type | Layer range | Height range (meters) |
|---|---|---|
| small high-rise | Floor 7-11 | 24-33 |
| high-rise | 12th floor and above | greater than 33 |

In addition to the differences in number of floors and heights, there are also significant differences between high-rise and small high-rises in terms of living experience, shared area, fire protection requirements, etc.:
| Comparative item | small high-rise | high-rise |
|---|---|---|
| Elevator configuration | Usually 1-2 parts | At least 2 (including fire elevators) |
| Sharing rate | 15%-20% | 20%-25% |
| Acquisition rate | 80%-85% | 75%-80% |
| fire protection requirements | Ordinary fire protection facilities | A refuge floor is required (over 100 meters) |

| Improve living | small high-rise | Lower floor area ratio, higher privacy |
| investment rental | high-rise | There are more small and medium-sized apartments with strong liquidity |
| Elderly care needs | small high-rise | Short elevator waiting time and quick emergency response |
5. Future development trends
According to industry analysis, the residential market may show the following trends in the future:
1.height limit policy: More cities will limit residential heights to less than 80 meters, promoting small high-rises to become the mainstream.
2.Technology upgrade: High-rise buildings will use more prefabricated technologies to reduce public housing costs and narrow the gap in housing availability with small high-rise buildings.
