Top 5 Largest Office Buildings in the US

Most people tend to think the largest office building in America is the Empire State building, and although it’s one of the tallest, it’s not the biggest office building there is in the US.

Before going through the list, try to guess one! 

5. McDermott Building in San Antonio, Texas with 4.463 million square feet.

The building is owned and managed by United States Automobile Association. Although it has only four floors, its long shape helps to hide its enormous size. It has been expanded numerous times since its creation in 1976.

4. Willis Tower in Chicago, IL with 4.5 million square feet. 

Until last year, it was the tallest building in the US, until One World Trade Center opened. Formerly named as Sears Towers, it has 108 floors and was finished in 1973. It still maintains its position as the eight tallest freestanding structure in the world.

2. Renaissance Center in Detroit, Michigan - 5.5 million square feet. 

It’s the tallest building in Michigan and its 7 connected skyscrapers are home to the world headquarters of General Motors in Detroit. The highest building of the “RenCen” has 73 floors.

Back in 1943, in the early years of WWII, the Department of Defense had 17 buildings spread all around, that’s why they decided to build The Pentagon, which today holds almost 24,000 workers between civilians and the four branches of the military. Its corridors have a length of 17.5 miles and its total floor area is three times the floor area of the Empire State Building. Although it’s a 5 story building, it also has 2 underground levels. 

Unfortunately, to have an office in three of these buildings, you either have to work for the Department of Defense, General Motors or the United States Automobile Association; but the good news is that if you’d like to have an office in Embarcadero Center or an office at The Willis Tower, you don’t need to be a millionaire or work for a large multinationals. Those two buildings have business centers offering executive suites for independent professionals and small companies. Give us a call and we’ll guide you through the process.
