I’d quibble a bit with the implied premise that changing elevators is such an absolute deal breaker. Speaking personally, I think I’d find it kind of a cool thing to do.
I just can’t quite imagine the conversation “Yeah - we could have built a building that was X meters but decided not to because it would have required passengers to change elevators.”
Its not the changing, its the added cost per square foot for effective usable space.
could simply transfer to the next tier elevator every 500 meters. At 4 meters per story that is every 125 stories.
