Citadel Center vs One Chicago East Tower

Comparing the Citadel Center and the One Chicago East Tower is interesting because they both rise in Chicago, IL, yet they were conceived by two different design teams, Ricardo Bofill Taller de Arquitectura and Goettsch Partners , and were completed at different points in time. They were finished more than a decade 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 One Chicago East Tower is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 971ft (296m) with 77 floors above ground, while the Citadel Center reaches 581ft (177m) with 37 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 Citadel Center and the One Chicago East Tower were designed in line with the aesthetic conventions of the Contemporary style.

At the time, this style was at the height of its popularity. So both Ricardo Bofill Taller de Arquitectura and Goettsch Partners followed what was in many ways expected of them, producing designs that fit comfortably within contemporary architectural norms, rather than breaking with convention.

The Citadel Center is primarily commercial, while the One Chicago East Tower is primarily residential.

The One Chicago East Tower offers 353 residential units.

Both towers provide significant parking capacity, with Citadel Center offering 211 spaces and the One Chicago East Tower offering 1100.

Both the Citadel Center and the One Chicago East Tower rely on a Frame structural system.

A frame structure uses a grid of columns and beams to carry the building's loads. This frees the walls from structural duties, allowing for flexible floor plans and larger windows.

They also employ the same type of facade, a Curtain Wall facade.

A curtain wall is a non-load-bearing facade hung from the structural frame. It is anchored to floor slabs and transfers only its own weight and wind loads, allowing for sleek, glassy exteriors.
