The Gogo Building, Corporate office building in West Loop, Chicago, US

The Gogo Building is a red-brick former warehouse at 111 N. Canal Street in Chicago's West Loop, with about 840,000 square feet of loft-style space. It is one of two surviving Butler Brothers Warehouse buildings along the Chicago River, and only its top block is still visible from the river. A cube bearing the Gogo logo tops the building.

The northern Butler Brothers warehouse was designed by Daniel Burnham and completed in 1913, a year after his death. After only seven years it was demolished and rebuilt exactly as before by the Chicago Union Station Company on the adjacent lot to make way for railroad construction along the river. Sterling Bay bought it in 2012 for $100 million and sold it to J.P. Morgan Asset Management in 2015 for more than $305 million.

The building takes its name from Gogo, a company known for providing in-flight Wi-Fi, which used it as its headquarters. That connection to aviation technology is an unusual identity for a former warehouse in the middle of a city.

The building sits right next to Ogilvie Transportation Center, which makes arriving by public transit straightforward. The Clinton CTA Green Line station and several bus routes are also within easy walking distance.

A lit cube on the roof displays the Gogo logo and can be seen clearly from street level below. The 16th floor holds a game and conference room area that most passersby never know exists.
