In the 19th century, “Go west, young man” was an invitation to settle the prairies or prospect for gold in Colorado and California. Now, architects fly to China to realize their dreams on a scale and at a speed that’s unimaginable in the West of today. Few have achieved more spectacular success than Steven Holl. When I was in Beijing in 2008, his Linked Hybrid was a construction site; now those towers have been matched by Sliced Porosity in Chengdu and Horizontal Skyscraper in Shenzen. To come are a pair of new museums near Tianjin, and a porous city within the fast-growing city of Dongguan, a neighbor of Shenzen. All five of these vast projects are explored in a masterpiece of miniaturization that is elegantly produced and fairly priced for a book of this quality.
