What Does the World’s Biggest Office Look Like?
You might think it is the HQ for Google, Apple, or Facebook. You might think it is based in Silicon Valley, or Manhattan. We would not even blame you if you thought it was a Chinese conglomerate in Shanghai, or even Hong Kong. Alibaba, or Tencent might even be on your radar. However, you might be surprised to learn that the world’s biggest office is actually The Pentagon. That is right. The home of the United States Department of Defense is the largest office in the world.
It is not just an office either. It is an entire network and operates much like a city. In terms of size and scale, its total floor area is more than 6.6 million square feet. The office space alone measures more than 3.7 million square feet. With seven floors, two underground and five above ground, (in addition to its five sided shape) it is an architectural triumph. Perhaps the most fascinating fact about The Pentagon is that a building the size of Washington D.C. could fit into any of the five wedges that makes up its unique shape. For more insights and detailed statistics about The Pentagon, its history, its operations, its architecture and its employees, have a look at this infographic produced by Dublin Office Centre below.
