 eating into the apartment value. And you get less and less value out of each successive floor, which is why if you know some of the ultra-tall buildings like the Empire State Building, not the Empire State Building, the Old World Trade Center Building, they actually had staged elevators where you take one elevator to a mezzanine on, I think it was the 78th floor, and then you take another elevator. So these super-tall buildings are only being built abroad because they're not actually very practical as office buildings.
