Really. It&#x27;s important to remember that every floor in a building has to support all of the floors above it - not just physically, but all the services and access for the floors above too. Above three floors or so, you also need extra infrastructure like pumps to get drinking water to the upper floors, tanks to store it, and elevators so people near the top don&#x27;t have to carry their shopping and furniture up all the flights of stairs. At the same time, you&#x27;re losing economies of scale because rather than building the same house 10 times, you&#x27;re building a one-off, with every floor having to be designed and analysed separately because it&#x27;s under different loading. And of course that one building has the same transportation, power, water and sewerage needs and generates the same amount of garbage as all 10 houses, but now you have much less space at ground level to satisfy those needs with.<p>And this just gets worse as the building gets taller. Eventually, the infrastructure required to add more floors removes so much usable space from all the floors below that it&#x27;s not ever economically viable to do so, which is why all the tallest skyscrapers are built for bragging rights these days.
