■ CONTEXT
■ CONTEXT
Despite hundreds of thousands of daily pedestrians, Yeomyeong-gil suffered from chronic litter, rampant smoking, and narrow walkways. Sanitation workers reported that “when one person litters, everyone follows.”

■ DESIGN APPROACH
■ DESIGN APPROACH
205 citizen surveys and sanitation worker interviews identified four core issues. Three reverse-design solutions were deployed: Local Cube (“the world’s cleanest spot” installed at the dirtiest location), Shadow Space (shade for bench areas), and Urban Camping (rest zone at idle commercial space).
■ SOCIAL INNOVATION
■ SOCIAL INNOVATION
The reverse design principle—placing the cleanest installation at the dirtiest spot—triggers a perceptual reversal that drives behavioral change. The project proved that providing places to rest makes streets cleaner, as litter correlates with lack of rest infrastructure, not moral failure.
