It's one building, the World Trump Tower in New York City, and he's not the only one doing it. The GQ piece is over the top in its bashing, IMO.
In real-estate there is only one key principle: location. Trump World Tower was built at a height equivalent to what would have been a 90-storey residential building in New York City at the time, maybe a few floors more, maybe a few floors less. Regardless, what he did was market the floor heights according to the average height of what his competition had sold before him or was selling. In his tower while you may have been buying on the 55th floor, that would equate to the 65th floor in a competing building. If both were for sale at $20 million, which would have the bigger sex appeal, the 65th floor unit or the 55th floor unit?
So what he did made perfect sense and has since been emulated.
