The Celltowa Building is an office building in Grand Theft Auto V, located at the intersection of San Andreas Avenue and South Rockford Drive in Little Seoul and Vespucci Canals, Los Santos, just west of Decker Park.
The building is most likely the head office of the Celltowa company in San Andreas. The tower is based on the LAUSD Headquarters, also known as Beaudry Center, a 29-story, 365 ft (111 m) skyscraper in Westlake, Los Angeles. The Celltowa Building, however, appears to be shorter than its real life counterpart. The building is not accessible and plays no role in the storyline whatsoever.
