OMA rethinks hillside areas in busan, south korea, with patchwork of terraces and towers
"Four residential categories emerged from the Busan Slope Housing study, including terrace houses, urban villas, row units, and towers. Each type is tested for slope, solar access, orientation, and area, while additional qualitative filters, proximity to public space, views, and visual variety helped refine their placement. Towers occupy high points, villas anchor urban centers, row houses follow ridgelines, and terraces nestle into steep pockets."
"During the Korean War, Busan became a city of refuge, its hillsides claimed by refugees who built improvised homes from salvaged materials. Over decades, these settlements evolved into dense, vibrant neighborhoods uniquely adapted to steep terrain. Today, those same hillsides sit on valuable land, but aging structures and narrow lanes no longer meet contemporary needs. The conventional response, tower estates, promises efficiency and comfort but erases the urban life that once animated these slopes."
OMA and partners propose a masterplan that translates the strengths of Busan's informal hillside neighborhoods into contemporary, livable urban form. Four residential categories—terrace houses, urban villas, row units, and towers—are defined and tested for slope, solar access, orientation, and area, with qualitative filters for proximity to public space, views, and visual variety. Towers occupy high points, villas anchor urban centers, row houses follow ridgelines, and terraces fit steep pockets. The plan composes interlocking zones organized by stairs, landings, terraces, and small squares to prioritize social circulation and communal outdoor life across contrasting Yeongju and Anchang sites.
