Riverside Plaza Building vs NBC Tower

Comparing the Riverside Plaza Building and the NBC Tower is interesting because they both rise in Chicago, IL, yet they were conceived by two different design teams, Holabird & Root and Skidmore, Owings & Merrill, and were completed at different points in time. They were finished over two decades apart.

This contrast within the same city allows us to see how different creative minds interpreted the evolving needs of Chicago across time.

Let's take a closer look!

The NBC Tower is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 561ft (171m) with 37 floors above ground, while the Riverside Plaza Building reaches 302ft (92m) with 26 floors above ground.

Of course, each project may have faced different briefs or regulatory constraints, which we don't really know about and could also explain the outcome.

Both the Riverside Plaza Building and the NBC Tower were designed in line with the aesthetic conventions of the Art Deco style.

The NBC Tower was designed at a moment when the Art Deco style was already in decline, making it more of a lingering expression of the movement. In contrast, the Riverside Plaza Building was built when the style still carried greater cultural weight.

Both the Riverside Plaza Building and the NBC Tower were designed to serve as commercial towers, and that has remained their main use since their completion, serving similar roles in the urban fabric.

The NBC Tower also provides 261 parking spaces.

These two towers illustrate the many possible ways to combine structure and enclosure in skyscraper design.
