Public Gasan is an office tower made up of several separate buildings, a 10-minute walk from Exit 3 of Gasan Digital Complex Station on Lines 1 and 7. Its ground floor and B1 house tenants including a sundae gukbap restaurant, Paik's Coffee, Mega Coffee, Starbucks, Downtowner, Klap Pizza and Knotted. Parking space is large, and the station exit is 600 metres away. Because the buildings stand apart, first-time visitors have trouble finding their way between the buildings and the underground parking garage.
