Mega Builds: Ten Colossal Construction Projects That Will Change Our World

“The best new popular science books of 2026” ―New Scientist

Construction is the most important industry in the world. The homes we wake up in, the schools where our children learn, the transportation networks we depend on, and the hospitals that care for us all exist because they were designed and built.

In Mega Builds, YouTube creator Fred Mills takes readers inside ten extraordinary megaprojects that are reshaping the modern world. Offering a front-row seat to some of the most ambitious engineering feats ever attempted, Mills delivers a fact-filled global tour that reveals how these vast undertakings are redefining what is possible.

Inside, you will discover:

• Why the world’s largest city has been built in one of the most inhospitable locations on Earth.
• How the vision of a single ruler in the desert is challenging our assumptions about the limits of design and construction.
• What compels us to build ever-taller skyscrapers and ever-faster trains.
• And how the scale of human imagination today is shaping the cities and infrastructure of tomorrow.

The story of our civilization is being written not only in books, but in steel, concrete, glass, and earth. Mega Builds reveals how the structures rising around us are defining the future of the man-made world.
