[1][2] This station serves one of the most affluent neighborhoods in Korea; the Samsung Tower Palace complex, which includes one of the tallest buildings in South Korea, has a direct passageway link with the station.
Another set of high-wealth residential apartments - the Dongbu Centreville - is also linked by an underground passageway.
Other nearby high-wealth apartments include Dogok Rexle complex and Daechi I-Park.
Due to pipes running underneath the 4-way road intersection at which this station is located, it is built deep underground.
For example, the Bundang Line platform is 6 floors below ground level.
