In August 2006, the whole station building was made into a large department store, called I'Park Mall.

The building now includes the railway station, subway station, the CGV cinema and several restaurants and shops, as well as housing the first building of the Yongsan Electronics Market.

There is a bridge connecting I'Park Mall and the Yongsan Electronics Market.

On floors B-1 and B-2 there is a very large E-Mart store along with a food court and a Burger King restaurant.

A duty-free store operated by HDC Shilla opened its doors in 2016, and the entire I'Park Mall underwent a major expansion in 2017.
