A Foldable Playground for One of the World's Densest Cities

The idea is to make finding a space to play ball in overcrowded Seoul a little easier.

In a city so dense there are two-month wait lists for tennis and basketball courts, a Seoul architecture firm has designed what it hopes is a solution: a foldable, transportable sports facility. Ji Hyun Park and his firm B.U.S. Architecture have come up with the “Undefined Playground.” Sides of the 12-foot-tall structure correspond to different games: soccer, tennis, basketball, and discus throw.

Other features, such as a hammock—for those who need a rest or perhaps the neighborhood bookworm—and a space that can be used as a ticket booth, snack bar, or sporting goods rental office are also built in.
