Imaginations and children run wild through Olson Kundig’s fanciful rooftop playground in Daegu, South Korea. This surprising project is the third in a series of roofscapes that the Seattle-based firm has conceived for Shinsegae, one of South Korea’s largest retailers. The series began when the client’s representatives, after visiting a children’s museum designed by Olson Kundig (for the Skirball Cultural Center in Los Angeles, Noah’s Ark), wanted to bring a similar concept to their stores. Olson Kundig partner Alan Maskin was immediately intrigued by the opportunity to explore a program that would be a first for the firm, whose diverse repertoire includes a range of building types—from residential to civic to cultural and commercial—as well as product design.
