The global boom in skyscrapers—why it’s happening now, how they’re made, and what they do to cities and people.

We are living in a new urban age, and its most tangible expression is the “supertall”: megastructures that are dramatically bigger, higher, and more ambitious than any in history.

Cities around the world are racing to build the first mile-high building, stretching the limits of engineering and design as never before. Paperback, 320 pages.
