Bluff Tower is an office complex in Grand Theft Auto V.
It appears as a 10-story, postmodern high-rise building. It is not accessible and plays no role in the storyline, although one of the 15 knife flights has to be performed between this building and the nearby Del Perro Heights.
The complex has a small terrace where office workers can be found during daytime. There's a sign that reads "Bluff Tower Office Complex" near the entrance.
