Seongnam’s steep old neighborhoods, Bundang’s broad apartment blocks and Pangyo’s glass offices look like three different cities. That contrast comes from three rounds of metropolitan policy rather than a simple march from old to new.
People arrived before the city
From 1969, families removed from informal housing in Seoul were relocated to hills then belonging to Gwangju County. Water, roads, sewage, transport and jobs lagged behind. Today’s dense stairways in Sujeong and Jungwon grew from residents building daily life on that unfinished ground.
Bundang followed a master plan
In the 1990s, Bundang was developed as a first-generation new town to ease Seoul’s housing shortage. Large blocks, parks, commercial zones and the Tancheon stream were planned together. Its spacious landscape reflects a different policy and investment sequence, not a more authentic version of Seongnam.
Pangyo turned housing into an employment center
After the 2000s, Pangyo New Town and Pangyo Techno Valley drew technology firms and commuters into Seongnam. Compare the slopes near Dandaeogeori, Bundang Central Park and Pangyo’s office district by public transport. The journey reveals how Korea repeatedly solved urban pressure by moving people, redesigning land and creating a new center beside the previous one.
