An office building is a building typology that falls under the umbrella of commercial building design. Designed to provide a suitable working environment for workers, offices nowadays are no longer just rows of grey cubicles or monotonous facades. Office designs are more worker-centric than ever today. 

Primarily, offices are the base function of this building typology. But they also have administrative support spaces, visitor support spaces, support spaces for employees, as well as maintenance and operation-related spaces. 

Here are 25 examples of the biggest office buildings around the world, in no particular order.
