- "The City within the City, the Arcadius Business Center boasts more AAA hedge funds, smoothie bars and executive suicides per square foot of office space than any other building in the business district. Welcome to the cutting edge."
- ―Dynasty 8 Executive description
This office building is easily recognizable for its unique circular design with interconnected towers, and features a helipad on its roof. It is located just right next to the Union Depository, connected by a bridge. It is based on the Westin Bonaventure Hotel, a 367-foot (112 m) tall, 35-story skyscraper in Los Angeles, California.
With the GTA Online: Further Adventures in Finance and Felony update, it is possible to acquire an office there through the Dynasty 8 Executive website.
Events in GTA V
- In the heist mission The Big Score, if players choose the obvious way to steal the gold, then Michael, Franklin and the gunman will have to fight their way through the building to the getaway car stopped in its underground parking lot after the gold is taken by Trevor.
- This is the building where Franklin covers Michael from in the mission Three's Company.
Events in GTA Online
- The Westin Bonaventure Hotel (the building's real-life counterpart) has 4 cylindrical towers, whereas the Arcadius Business Center only has 3.
- The Westin Bonaventure Hotel bears the number 10 on its helipad, where as in-game it is 11.
- The triangular logo on the building is identical to the player icon on the minimap in the HD Universe.
- A building complex with the same design as the Arcadius Business Center is featured in GTA San Andreas, located next to the Atrium.
