150 North Riverside Plaza is a highrise building in Chicago, Illinois, completed in 2017. The building is 53 stories tall. The building occupies a two-acre site on the west bank of the Chicago River, whose size and location demanded an unusually small base for the building. The building features 1.2 million square feet of leasable office space. Due to its unique superstructure design, it encompasses just 25 percent of the lot.


As required by the city of Chicago for any new building, the developer was required to set aside part of the lot size for public park space. The remaining 75 percent of the project site is reserved for a public park, amphitheater, and riverwalk.[3] The site is built with air rights over tracks that carry Metra and Amtrak trains into Chicago Union Station. The building aims to gain LEED gold certification.

The west side of the building features a lobby with a glass wall that is nearly 100 feet tall at its peak. The architect's intention is to connect the interior and exterior visually.[3]

One signature aspect of 150 North Riverside building is the way the office floors cantilever out from the central core. The building is constructed with a smaller base for a height of 8 stories (104ft), but the building cantilevers out to the full size of the office floor space.[4]


Variously referred to by popular names, "The Tuning Fork" or "The Guillotine", the building has become a highlight of architectural boat tours. Architecture critic Blair Kamin in his positive review calls it "a persuasive blend of the pragmatic and dramatic." [5]
