Moreover, in the early development of super high-rise buildings, the main purpose is to concentrate all upstream and downstream companies in one building, facilitate production and maximize output value.

On the one hand, it puts forward restrictions on super high-rise buildings: cities with a permanent resident population of less than 3 million in the urban area strictly restrict the construction of super high-rise buildings of more than 150 meters and are not allowed to build super high-rise buildings of more than 250 meters; Cities with a permanent resident population of more than 3 million in the urban area shall strictly restrict the construction of super high-rise buildings of more than 250 meters and shall not build super high-rise buildings of more than 500 meters.
02 when the city develops to a certain stage, it is no longer applicable to super high-rise buildings.
Think about it, do you still need to build so many super high-rise buildings? Especially according to the analysis of Jones Lang LaSalle, relying on the developed tertiary industry, the first tier cities have a little surplus, but there is surplus in line 1.5, line 2 and line 3.
